part arrived.
b. Fill out and attach the enclosed UPS shipping document.
c. Ship the part to Daktronics.
3. Daktronics will charge for the replacement part immediately, unless a qualifying

days, or Daktronics will charge the full purchase price.
If the part is still defective after the exchange is made, please contact Customer Service
immediately. Daktronics expects immediate return of an exchange part if it does not solve
the problem. The company also reserves the right to refuse parts that have been damaged

DAKTRONICS
WARRANTY AND LIMITATION OF LIABILITY
This Warranty and Limitation of Liability (the “Warranty”) sets forth the warranty provided by Daktronics with respect to the Equipment. By
accepting delivery of the Equipment, Purchaser agrees to be bound by and accept these terms and conditions. All defined terms within
the Warranty shall have the same meaning and definition as provided elsewhere in the Agreement.
DAKTRONICS WILL ONLY BE OBLIGATED TO HONOR THE WARRANTY SET FORTH IN THESE TERMS AND CONDITIONS UPON RECEIPT OF FULL
PAYMENT FOR THE EQUIPMENT.
1.
Warranty Coverage
A. Daktronics warrants to the original end-user that the Equipment will be free from Defects (as defined below) in materials and
workmanship for a period of one (1) year (the “Warranty Period”). The warranty period shall commence on the earlier of: (i) four
weeks from the date that the equipment leaves Daktronics’ facility; or (ii) Substantial Completion as defined herein. The warranty
period shall expire on the first anniversary of the commencement date.
“Substantial Completion” means the operational availability of the Equipment to the Purchaser in accordance with the
Equipment’s specifications, without regard to punch-list items, or other non-substantial items which do not affect the operation of
the Equipment.
B. Daktronics’ obligation under this Warranty is limited to, at Daktronics’ option, replacing or repairing, any Equipment or part
thereof that is found by Daktronics not to conform to the Equipment’s specifications. Unless otherwise directed by Daktronics,
any defective part or component shall be returned to Daktronics for repair or replacement. Daktronics may, at its option,
provide on-site warranty service. Daktronics shall have a reasonable period of time to make such replacements or repairs and
all labor associated therewith shall be performed during regular working hours. Regular working hours are Monday through
Friday between 8:00 a.m. and 5:00 p.m. at the location where labor is performed, excluding any holidays observed by either
Purchaser or Daktronics.
C. Daktronics shall pay ground transportation charges for the return of any defective component of the Equipment. If returned
Equipment is repaired or replaced under the terms of this warranty, Daktronics will prepay ground transportation charges back to
Purchaser; otherwise, Purchaser shall pay transportation charges to return the Equipment back to the Purchaser. All returns must
be pre-approved by Daktronics before shipment. Daktronics shall not be obligated to pay freight for any unapproved return.
Purchaser shall pay any upgraded or expedited transportation charges.
D. Any replacement parts or Equipment will be new or serviceably used, comparable in function and performance to the
original part or Equipment, and warranted for the remainder of the Warranty Period. Purchasing additional parts or Equipment
from the Seller does not extend this Warranty Period.
E. Defects shall be defined as follows. With regard to the Equipment (excepting LEDs), a “Defect” shall refer to a material
variance from the design specifications that prohibit the Equipment from operating for its intended use. With respect to LEDs,
“Defects” are defined as LED pixels that cease to emit light. The limited warranty provided by Daktronics does not impose any
duty or liability upon Daktronics for partial LED pixel degradation. Nor does the limited warranty provide for the replacement or
installation of communication methods including but not limited to, wire, fiber optic cable, conduit, trenching, or for the purpose
of overcoming local site interference radio equipment substitutions.

CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OR CONDITIONS OF
MERCHANTABILITY AND FINTESS FOR A PARTICULAR PURPOSE. SPECIFICALLY, EXCEPT AS PROVIDED HEREIN, THE SELLER

PURPOSE FOR WHICH PURCHASER MAY BE BUYING THE EQUIPMENT. ANY IMPLIED WARRANTY IS LIMITED IN DURATION TO THE

F. Any statements made about the product by salesmen, dealers, distributors or agents, unless such statements are in a written
document signed by an officer of Daktronics. Such statements as are not included in a signed writing do not constitute
warranties, shall not be relied upon by Purchaser and are not part of the contract of sale;

Daktronics shall be under no obligation to furnish continued service under this Warranty if alterations are made to the Equipment
without the prior written approval of Daktronics.
It is specifically agreed that the price of the Equipment is based upon the following limitation of liability. In no event shall
Daktronics (including its subsidiaries, affiliates, officers, directors, employees, or agents) be liable for any special, consequential,
incidental or exemplary damages arising out of or in any way connected with the Equipment or otherwise, including but not
limited to damages for lost profits, cost of substitute or replacement equipment, down time, lost data, injury to property or any
damages or sums paid by Purchaser to third parties, even if Daktronics has been advised of the possibility of such damages. The
foregoing limitation of liability shall apply whether any claim is based upon principles of contract, tort or statutory duty, principles
of indemnity or contribution, or otherwise.
In no event shall Daktronics be liable to Purchaser or any other party for loss, damage, or injury of any kind or nature arising out of
or in connection with this Warranty in excess of the purchase price of the Equipment actually delivered to and paid for by the
Purchaser. The Purchaser’s remedy in any dispute under this Warranty shall be ultimately limited to the Purchase Price of the
Equipment to the extent the Purchase Price has been paid.
4.
Assignment of Rights
The Warranty contained herein extends only to the original end-user (which may be the Purchaser) of the Equipment and no
attempt to extend the Warranty to any subsequent user-transferee of the Equipment shall be valid or enforceable without the
express written consent of Daktronics.
5.
Dispute Resolution
Any dispute between the parties will be resolved exclusively and finally by arbitration administered by the American Arbitration
Association (“AAA”) and conducted under its rules, except as otherwise provided below. The arbitration will be conducted
before a single arbitrator. The arbitration shall be held in Brookings, South Dakota. Any decision rendered in such arbitration
proceedings will be final and binding on each of the parties, and judgment may be entered thereon in any court of competent
jurisdiction. This arbitration agreement is made pursuant to a transaction involving interstate commerce, and shall be governed
by the Federal Arbitration Act.
6.
Governing Law
The rights and obligations of the parties under this warranty shall not be governed by the provisions of the United Nations
Convention on Contracts for the International Sales of Goods of 1980. Both parties consent to the application of the laws of the
State of South Dakota to govern, interpret, and enforce all of Purchaser and Daktronics rights, duties, and obligations arising
from, or relating in any manner to, the subject matter of this Warranty, without regard to conflict of law principles.
7.
Availability of Extended Service Agreement
For Purchaser’s protection, in addition to that afforded by the warranties set forth herein, Purchaser may purchase extended
warranty services to cover the Equipment. The Extended Service Agreement, available from Daktronics, provides for electronic
parts repair and/or on-site labor for an extended period from the date of expiration of this warranty. Alternatively, an Extended
Service Agreement may be purchased in conjunction with this warranty for extended additional services. For further information,

I. Introduction
1. Intended Application. This amplifier is intended for installation in a
loudspeaker cabinet to power the components in that cabinet.
2. Parts Check List. The amplifier comes with an AC power cord and gaskets.
The user must provide input and speaker cabling appropriate for the application.
3. Installation in the cabinet. The speaker cabinet must be 2 cu ft or larger to
allow sufficient air for cooling. It is recommended that the amplifier be recessed
into the speaker cabinet 3/8” to prevent abrasion and possible damage to the
heatsink and connectors. It is not necessary or recommended to create a separate
subenclosure for the amplifier in the speaker cabinet. Allow at least 6 inches of
space around the vents in the back of the amplifier. Do not block the circulation of
air around the amplifier. Do not place flammable materials near the amplifier.
4. Panel Layout. The arrangement of the connectors may differ from model to
model.

Getting Started
1. Speaker Connections. Speakers are connected to the internal amplifiers by the
white 6 pin AMP mate n lock connector on the rear panel. The mating connector
is AMP MATE-N-LOC 350715-1 (Digikey part number A14288-ND). The
individual pins are Amp 350552-1 (Digikey A14303-ND) for .130 - .200 inch
diameter wire insulation. Up to 14 gauge wire is accommodated by these pins.
There is a relatively cheap hand tool that will crimp these pins. It is a Molex
63811-1000, Digikey part number WM9999-ND for $38. A better tool is the
AMP 90546-1. A cheap tool to remove the pins if (when?) you make a mistake is
AMP 305183-R, Mouser part number 571-305183. A better tool is the AMP
318851-1.
2. We recommend using twisted pair wiring to the speakers of at least 16 gauge.
Both + and – wires are “hot”, so they should not be allowed to touch any
other wire, the amplifier cabinet, or ground. The channels are brought out to
the plug as shown in the drawings below.
3. Channel 1 is the amplifier in the ASP module and is connected to the Low
Frequency speaker in SP1, SP2 and SP3 models. In SP2 models, Channel 2 is the
slave amplifier and is connected to a High Frequency speaker. In SP3 models,
Channel 2 is connected to the Mid Frequency speaker and Channel 3 is connected
to the High Frequency speaker.

4. AC mains connection. The mains disconnect of the amplifier is the AC plug.
It must be removed from the AC service to completely remove power from the
amplifier. The AC mains power cord is connected to the front panel through the
blue Neutrik Powercon. The mating cable end connector is NAC3FCA. The gray
Powercon connector is a power outlet tht allows looping to adjacent amplifiers.
The looping outlet mating cable connector is NAC3FCB. Do connect equipment
to the power outlet that exceeds the marked rating of the outlet.
5. Signal connection. Signal input is through locking XLR connectors. The input
is transformer balanced. If an unbalanced source is connected, make sure that pin
3 is connected to pin 1 (ground). The input impedance is 15K Ohms.
III. Basic Operation
1. 115/230 V switch. This switch changes the range of voltages accepted by
the amplifier. Make sure it is set to the proper range before connected the
amplifier to AC. Once set to the proper range, the amplifier will regulate the
internal voltages so that output power does not change with supply voltage. If the
switch position is changed, the fuse must be changed to the proper value as
well.
2. Powering up the amplifier. Before turning on the amplifier, check to make
sure the voltage selector switch is set to the proper range for your service.
Connect the input, lower the volume control, and turn on all preceding equipment
in the signal chain. To turn on power, press the side of the power switch
marked “ON”. After applying the power, check that the mute switches are in the
“out” position and slowly raise the volume.
3. LED Indicators. “CLIP” indicates when Channel 1 is clipping. “PROT”
indicates when the power supply protective circuitry has been engaged. It may be
necessary to cycle the power to reset the protective circuitry. “PWR” indicates
that power is present in the amplifier. “SIG” indicates that signal is present at the
input of the amplifier.
4. Muting switches. These switches mute the individual amplifier channels for
setup and troubleshooting purposes.
5. Volume control. This lowers in the volume in 1 dB steps down to –12dB, then
the steps are larger until the input signal is completely shut off.
6. 80 Hz high pass filter switch. This inserts an analog 12dB/oct Butterworth
high pass filter. It is sused for combining a full range system with a subwoofer or
for restricting the low frequencies in speech only systems.
7. Program Select switch. This switch allows the selection between two DSP
programs stored in EEPROM. The AC power must be cycled off and on for the
selected program to be loaded.
IV. Advanced Operation
1. Software Installation and PC Interface Setup.
2. Make sure power is off on amplifier and computer
3. Plug the interface board into the parallel port of the computer
4. Plug the interface cable into the interface board and the SP amplifier.
5. Plug the speaker cable into the back of the SP1 and the loudspeaker. Channel
1 is LF, Channel 2 is MF and Channel 3 is HF.
6. Plug in XLR cable to input from music or test signal source. Make sure signal
is OFF.
7. Plug in power cord to SP amp and turn it on.
8. Turn on computer. Enter CMOS setup. The first screen the computer shows
while booting frequently tells you which key to press to enter Setup mode.
9. Set the parallel port to EPP mode in CMOS Setup.
10. Save setup and boot to Windows.
11. Unzip the files in ALE5.2.zip. Run Setup.exe to install.
12. Unzip the files in DASDCT3.1.zip. Run Setup.exe to install.
13. Unzip the files in softwareupdate.zip into the “DCT3.1” folder. Overwrite
any existing files of the same name.
14. To Load an Existing Configuration
15. Plug interface cable from PC to amplifier before turning amplifier ON. This
ensures it will come up in slave mode and accept commands from the PC.
16. Mute all channels from the faceplate of the SP amplifier.
17. Start DAS DCT 3.1 program
18. Open TAS3100Example.dat file in folder “DCT3.1”
19. After a few seconds you will see the EQ GUI box. Select “Detail GUI A”
20. LOAD your configuration file “_____.cfg”. The configuration file SP2-500250.cfg has a typical 2kHz crossover.
21. You may now unmute the amplifier channels and measure the response.
22. To save the configuration into the amplifier so it is available with the
computer removed, select EEPROM on the EQ GUI panel. Select “EEPROM
Write”. After several seconds you will see “EEPROM Done” Click OK and close
the EEPROM panel.
23. Turn off the SP amplifier. Remove the interface cable. Turn on the SP

you may reload them from the FILE menu and proceed to modify them as shown
in the next steps.
30. EDIT menu select Edit Filter Parameters.
31. Add filters to table.
32. EQ filters. Remember when adding eq filters that “bandwidth” in the ALE
program is expressed in Hz, not octaves. If translating from a processor that
expresses bandwidth in octaves, BW in Hz = center frequency F * BW in octaves.
If translating from a processor that express bandwidth as Q, BW in Hz =
1.41*F/Q
a. Linkwitz-Riley Filters. Second order filters may be chosen directly on
the Filter Parameters Grid. Fourth order (24dB/oct) versions, also know as
“squared Butterworth” filters, are designed by adding two identical
Butterworth filters. So for 24 db/oct L-R at 1000Hz make two 1000Hz
entries under Butterworth 2-LP.
b. Third order filters. Are not in the Filter Parameters Grid. They may be
designed by using the Low Vari Q and High Vari Q tabs. For Butterworth
response, one Butterworth-1 filter and one Vari Q filter with a Q of 1.
c. Fourth order Butterworth. Use two Vari Q filters, one with a Q of 1.31
and the other with a Q of 0.541.

Software Tools
Basic Screen Elements
The main screen of the NEXIA software has several sections. The Layout occupies the largest portion
of the main screen, at the lower-right. This is the area where system design actually occurs, with the
placement & connection of Component Objects. Component Objects represent the individual
hardware devices and signal processing blocks within the system. Other objects include Lines (for
connecting components) and Text (for labeling the system). If a system becomes too big to fit the
Layout, a Bird's Eye View is available to aid navigation. A Property Sheet, at the lower-left of the main
screen, provides an editable table of attributes regarding the Layout and its associated objects. A
Processing Library of available Component Objects is displayed, at the lower-left of the main screen,
for drag & drop placement into the Layout. However, the Processing Library can be closed, increasing
the width of the Layout, and Component Object selection can then be accomplished using the Object
Toolbar, located directly above the Layout. The Object Toolbar also provides the option of either a
select or a text cursor. Above the Object Toolbar is the Format Toolbar, which allows customizing of
text & colors used in the Layout and associated objects. Above the Format Toolbar is the Layout
Toolbar, which affects certain aspects of Layout, such as the grid, rulers, zooming, & alignment of
Component Objects. The Layout Toolbar can also open editing/information sheets for properties,
objects, & layers. Above the Layout Toolbar is the Network Toolbar, with functions related to
communications, configuration, maintenance, and testing of the system network. Above the Network
Toolbar is the Standard Toolbar, with file functions such as new, open, & save, plus additional
functions such as cut, copy, paste, print, & help. The Standard Toolbar also includes the Compile
function, which will generate a new configuration file, while checking system layout/connections &
determining DSP resource allocation. Above the Standard Toolbar are the Main Menus, which
provides all of the toolbar functions mentioned above, with several more in-depth editing functions.
Along the bottom edge of the main screen is a Status Bar, which gives indication of object quantity,
location, & size, as well as layer name, visibility, & locking. The location and shape of all toolbars,
including the Processing Library, may be changed to fit the user's preference.
5
Layout
The Layout occupies the largest portion of the main screen, at the lower-right. This is the area where
system design actually occurs, with the placement & connection of Component Objects. Component
Objects represent the individual hardware devices and signal processing blocks within the system.
Other objects include Lines (for connecting components) and Text (for labeling the system).
Component objects can be placed into the Layout from the Processing Library, the Object Toolbar, or
the Processing Library Menu. A Property Sheet provides an editable table of attributes regarding the
Layout and its associated objects. The Layout has fixed dimensions of 16384x16384 pixels (approx.
163.75" square). Therefore, horizontal & vertical scroll bars are used to navigate within the Layout.
Zoom In/Out and a Bird's Eye View are also available as navigational aids, and can be accessed from
the Layout Toolbar or View Menu. The Ruler and Grid may be turned on/off from the Layout Toolbar,
and the background color of the Layout may be changed from the Format Toolbar. Grid Settings, such
as snap-to-grid, grid spacing, and guideline spacing, are available from the Layout Menu. Minimize,
Down-Size, and Close buttons for the Layout are located in the upper-right corner of the main screen.
Right-clicking over the Layout provides a pop-up menu of options.
Bird's Eye View
The Bird's Eye View provides a thumb-nail sketch of the entire
system design, to aid navigation within the Layout. Bird's Eye View
initially covers an area of only 8" x 5", but will automatically increase
size to cover a larger system design. A black rectangle frames the
viewable area. The rectangle may be dragged to view any location
within the system design. The rectangle also has handles to re-size
the viewable area, from a minimum of 4" x 2.5" to a maximum of 16"
x 10". The Bird’s Eye View can be made dockable (see Options). If
Bird’s Eye View docking is enabled, a Menu icon (upper-right of
title-bar) allows the Bird’s Eye View to be docked or floating, and to
be hidden (closed) or to utilize Auto Hide (if docked). The menu
may also be accessed by right-clicking over the Bird’s Eye View.
The thumb-tack allows the Bird’s Eye View to remain open

can be organized with regards to object types, system
segments, or any other criteria. The Default Layer always
remains, but other Layers may be created or removed, using
Add & Delete. Layers may be selected directly from the list.
Up & Down change the position of a Layer in the list only
(Layers are not stacked, so this does not affect Tab Order or
visual overlapping). All objects in a given Layer can be
selected with Select. Added Layers can be given a custom
Name. View turns on/off visibility of a Layer in the Layout.
NOTE: Components cannot be selected when the current
Layer is invisible. Lock prevents a Layer from being
changed or selected. Lock & View may also be accessed by
double-clicking on the corresponding icons within the list.

Disconnect From System
Ends communications with selected NEXIA systems on the
network. See System Network Considerations. System design
data is retained in software after disconnect.
Send Configuration
Transmits system design data to selected NEXIA devices in the
system. See System Network Considerations. Before data can be
transmitted, a system design file (.NEX) must first be opened, then
connected to a system, and have NEXIA device IP addresses assigned
(see Device Maintenance). Send Configuration will
automatically Compile the system design, and reset the hardware
devices, before sending the new configuration.
Sync Data
Re-synchronizes the software with all connected NEXIA devices in the system.
NOTE: An 'Auto-Update' feature allows software to detect system changes,
and automatically re-synchronize with the devices where changes have occurred.
Start Audio
Enables audio signal flow within the selected system. See
System Network Considerations. Start Audio is available
only after Send Configuration has been successfully performed.
Stop Audio
Disables audio signal flow within the selected system.
See System Network Considerations.
17
Device Maintenance
Provides an editable table of network related settings for selected NEXIA
devices. Opens Device Maintenance dialog box. Device Maintenance settings
include Date/Time, IP Address, Description, Serial Number, Reset/Initialize,
Update Firmware, and Disconnect From Network. (See System Network Considerations.)
Device Maintenance Dialog Box
Device Information provides information (such as firmware version, input/output configuration, etc.)
regarding the selected device. Set IP Address assigns a device IP Address such as 192.168.1.X (where
range of X = 1~254). The factory default IP Address is 192.168.1.101. However, IP Addresses cannot
be duplicated, even in simple (NEXIA only) networks, and must be carefully managed when network
topology is more complex. Set Device Description allows the selected device to be given a descriptive
name. Serial Port Setting selects the baud rate for RS-232 communications (default 38,400) and allows
responses to NTP commands to be suppressed. Reset/Initialize clears all current system design data
from the selected device. This happens automatically whenever a new system design file (.NEX) is
uploaded (see Send Configuration).
18
Update Firmware produces a file browser window.
When a valid firmware file is selected, a dialog window is produced that shows all discovered devices
in a table with columns indicating System ID, Device IP Address, and other details for each unit. To
specify a unit for updating, place a check in that unit’s Update box. Buttons are provided to Select All
entries and Clear All entries. Press the Update button to perform the firmware update on the selected
units and Cancel to exit this window.
19
RCB Devices opens a list of devices connected to the Remote Control Bus of the selected NEXIA
device. Identify Device causes indicators on the selected device to flash (for physical location). Set
Device Description allows the selected device be given a custom name. Calibrate is enabled only if a
Voltage Control Box (VCB) is the selected device (see VCB Calibration). Update Firmware allows future
firmware updates to be loaded into the selected device. The information in this list (including Serial #) is
used to establish proper association between the external physical controls and their corresponding
component counterparts in the layout (see Equipment Table).

Presets Menu
Select any function from the menu shown below for more information
Menu Items
Create/Edit/Recall
Provides the Create/Edit Preset dialog box, for creating, editing, saving, and recalling presets. Each
preset can have a custom Preset Name, and will automatically be assigned a Preset ID number. A
check-box is provided to assign the selected preset to be Set As Power-Up Default. This preset will
automatically be recalled each time the system is powered up. A check-box is also provided to assign
the selected preset to Mute Audio During Recall. If audio is not muted during recall, some
processing noises may be audible. Component Objects (DSP Blocks) may be selected, and added or
removed from any preset using the Add Sel, Add All, Rem Sel, and Rem All buttons. With certain
components, the Edit Block Fields button will provide a matrix of check-boxes, which allows selection
of very specific settings within the selected block to be affected by the preset. If only specific settings
within a block are saved to a preset, then its icon will become highlighted in the list. NOTE: Presets
that employ Edit Block Fields, and have half or more of the block settings selected, will occupy a much
greater amount of preset memory than would a preset affecting the entire block. These features allow
presets to be customized to affect Component Objects (and specific settings) individually, in groups, or
as an entire system. Initially, all Component Objects in the Layout (and all their settings) will be
selected and included in the preset. Individual components selected in the list become highlighted in
the Layout. Right-clicking a selected component in the list allows the control dialog to be opened, the
associated block to be located in the Layout, or Edit Block Fields to be accessed (if available). This
makes it easy to change individual component settings within the preset being created/edited. Also,
right-clicking a block in the Layout, and selecting ‘Add To Last Recalled Preset’, is a convenient way to
add blocks to existing presets, or even update settings of blocks already in the presets.
28
A tab at the upper-right of the Create/Edit Preset dialog box provides
additional functions. Next ID and Prev ID allow selection from a list of
existing presets. Recall retrieves all settings stored in the selected
preset. New selects the next available Preset ID, for creation of a new
preset. Save will overwrite the selected Preset ID with all changes,
including Preset Name. Save As will write changes into the next
available Preset ID. Delete will remove the selected preset from
memory. Send will send all saved presets to the devices in the system.
NOTE: Be sure to use Recall before attempting to edit an existing
preset. Otherwise, the preset could be overwritten with settings from a
previous preset, and any settings made since it was recalled.
A tab at the lower-left of the Create/Edit Preset dialog box provides a
list of existing presets. Left-clicking selects a preset. Double-clicking
recalls a preset (as indicated by a green arrow to the left).
Recall
Provides the Recall Preset dialog box, for recalling existing presets. Recall Preset will retrieve all
settings stored in the selected preset. Presets can also be recalled using components called Preset
Buttons and Remote Preset Buttons, which can be placed into the Layout from Controls on the Object
Toolbar.
29
Custom Blocks Menu
Multiple component objects may be merged into a single custom block.
Custom Blocks can simplify the design process by integrating frequently
used component combinations, and provide password protection for
intellectual property such as unique processing and component settings.
Select any function from the menu shown below for more information
Menu Items
Create Custom Block Document
Create Custom Block Document opens a new
NEX file, and a Create Custom DSP Block
screen determines the quantities of audio and
logic inputs/outputs necessary for the custom
block. These quantities should match the
combined totals from all components to be
included in the custom block. Once quantities
are selected, appropriate APT (Audio PassThrough) and LPT (Logic Pass-Through)
blocks are placed into the layout. The desired
components are then placed within, and
connected to, the APT and LPT blocks.
Components may be added individually, or
copied as a group from a separate NEX file.
Certain components (such as NEXIA Hardware and Control Devices) cannot be placed within custom
blocks. The number of components in a custom block is limited only by DSP resources available
within a single hardware unit. Once the components are placed and connected, select Merge Into
Custom Block from the menu.
30
Merge Into Custom Block
Merge Into Custom Block checks for errors (such
as inappropriate connections) as it packages the
components into a single block. The resulting
block can then be copied into the Processing
Library (and named) for use in future NEX design
files. The Custom Block NEX file should also be
saved as a reference for subsequent
modifications.
Control settings for each component within a Custom Block can be adjusted (see Component Object
Properties). Double-clicking a Custom Block in a design layout produces an Open Custom Block
Control Dialogs screen. Open Custom Block Control provides direct access to the control dialogs for
selected components. View Custom Block Layout displays the individual components within the
Custom Block, which can then be accessed normally. Control Settings are saved as part of the
Custom Block NEX file.
Control settings also remain part of any Custom
Block which has been copied into the Processing
Library. These control settings may again be
addressed once the Custom Block is placed into
a new NEX design file. However, to prevent
tampering with control settings, a Password
Level may be specified for a Custom Block via
the Property Sheet. This option is available only
while working in the Custom Block NEX file.
If components or connections within a merged Custom Block require modification, then select Split Into
Component Blocks from the menu. Merge and Split operations are available only while working in the
Custom Block NEX file.
31
Split Into Component Blocks
Split Into Component Blocks allows component and connection changes to be made to a Custom
Block. Merge and Split operations are available only while working in the Custom Block NEX file.
32
Tools Menu
Select any function from the menu shown below for more information
Menu Items
Passwords
Provides the Set Passwords dialog box, for establishing password protection in selected NEXIA
devices. Set Password allows up to four levels of protection, each with a unique password (6~16
characters). Designer level allows access to system configuration, component settings,
storing/recalling presets, and password assignments. Technician level limits access to component
settings and storing/recalling presets. User level limits access to recalling presets only. However,
Level Control and Meter dialog boxes can be minimized for User access (see Customizing Component
Objects). Guest level limits access strictly to connection and viewing only.
NOTE: You must first Send Configuration to a device before a Password can be assigned.
Passwords cannot be assigned to non-configured devices or design layouts.
33
Equipment Table
Provides a table of NEXIA devices used in the system design. Devices are automatically added to the
Equipment Table whenever CS, PM, SP, VC, or TC blocks are placed into the Layout. When
connected to the network, specific hardware devices may be chosen (by Serial #) for use in the
system. When connected to the system, Serial # and Device Description Label becomes 'read-only'
information.
An RCB tab at the lower-left of the Equipment Table dialog box provides an editable table of devices
connected to the Remote Control Bus of the NEXIA devices in the system design. This table is used to
establish proper association between external physical controls and their corresponding component
counterparts in the layout. Each DevID (control component) should be matched to an appropriate
Serial # (physical control). The DevID number can be found in the right corner of control component
objects in the layout, when 'Display Device Assignment in DSP Block Info Field' is selected from
Display Options. Serial # and Device Description Label information can be found for the physical
controls using Device Maintenance.
34
Object Inspector
Provides a list of all objects within the Layout, along with their Object Codes,
Text Labels, Unit numbers, Instance ID numbers, and Instance ID Tags.
Layout Compile Results
Provides the most recent Compile results. This information may be viewed at any time.
35
Signal Path Identifier
Provides a temporary color-coded identification of all signal paths (Lines) which are associated with a
selected Line Object. See example below, where the selected input is shown as being routed to three
outputs. Signal Path Identifier is represented by a thin dashed red line. However, the Signal Path
Identifier color may be changed in Display Options. When using Signal Path Identifier on a compiled
design, propagation delay will appear in the Status Bar. Persistent Signal Path Identifier is available
in Normal Mode (follows subsequent line selections), Locked Mode (remains on original line selection),
or Off (temporary selection). If the selected Line Object includes identifying text (see Line Property
Sheet), that text will be temporarily imposed on all lines being indicated by Signal Path Identifier.
36

identifier numbers, or simply the word 'Recall'. Allows docking capability of Bird's Eye View to be
enabled. Allows default Grid "ON" for new Layouts to be disabled. Allows Start Audio to be prompted,
automatic, or manual when sending new configuration.
37
Display Options
Allows DSP Blocks (Component Objects) to display Device Assignment numbers, as determined by
Compile. (Device Assignments can be changed in the Property Sheet.) A second option is to display
DSP Resource Requirements, which indicates the block's DSP usage as a percentage of total DSP
resources available within a single hardware unit. Allows color of Signal Path Identifier to be
changed. Allows selection of optional Application Visual Styles.
38
Compile Options
Allows Global Delay Equalization to be disabled system-wide (see System Compiling Considerations).
Allows Local Delay Equalization to be enabled for I/O blocks which have Global Delay Equalization
turned off (provides localized delay equalization for multi-input DSP blocks such as mixers). Allows
automatic re-assignment of Instance IDs during Compile or Send Configuration. Allows Compile
function to be stopped if warning occurs.
39
Network Options
Network Device Discovery Method allows the user to choose a method to Connect To Network.
UDP Broadcast is the default 'message' based routine, which looks for devices on a common network.
TCP User Supplied Device List allows connection to a specified list of device IP addresses. This
approach is 'communication' based, and allows the user the ability to: avoid firewall conflicts; create
custom device lists; access multiple sub-networks; connect remotely via modem.
Edit Device List allows creation of the TCP User Supplied Device List. Use Add to create a new
entry, double-click under Subnet Address, and enter only the first three sets of numbers. Then click
Edit Nodes and select the appropriate final set of numbers for the intended device(s).
40
Default Network Interface Card allows selection of a specific network interface card (NIC), when
multiple cards are available on the computer being used to run Nexia software.

CS Hardware
Mic/Line Inputs: These ten plug-in barrier strip connectors provide balanced input for microphone or
line level signals. For unbalanced input, wire high to (+) and ground to both ( ) & (-). Settings for
these inputs are accessed by double-clicking the CS Input 10 Channel block in the Layout.
Outputs: These six plug-in barrier strip connectors provide balanced output of microphone or line
level signals. For unbalanced output, wire high to (+) and ground to ( ), leaving (-) un-connected.
Settings for these outputs are accessed by double-clicking the CS Output 6 Channel block in the
Layout.
NexLink: These two RJ45 jacks provide the NexLink Tx (transmit) and Rx (receive) connections. Up
to four NEXIA devices may be linked together to share digital audio signals. Tx on one NEXIA device is
connected to RX on the next device. NexLink utilizes standard CAT5 cabling, with a maximum
recommended length of 5 meters per cable. When multiple NEXIA devices are placed in the Layout,
NexLink blocks allow routing of digital audio between linked devices.
Ethernet: All NEXIA devices use Ethernet, both for system programming and control. Programming is
accomplished using the NEXIA software provided with each unit. NEXIA software is for PC computers,
with Windows® XP Professional/Vista operating system required. The PC computer must have a
network card installed, which supports 10/100BaseT Ethernet. A 10/100BaseT Ethernet switch (not
hub) is required when networking multiple units (see System Network Considerations). Ethernet
utilizes standard CAT5 cabling, which has a specified maximum length of 100 meters. However,
Ethernet switches which provide fiber-optic interface can be used to extend the physical distance
between units within a network.
Serial Control Port: After initial programming and configuration, NEXIA systems may be controlled by
RS-232 or Telnet communications from third-party control systems such as AMX® or Crestron®, using
the Serial Control Port. Also, external devices may be controlled via the Serial Control Port, by utilizing
Command String blocks within the NEXIA system design.
Remote Control Bus: The Remote Control Bus provides connection for Volume 8, Select 8,
Volume/Select 8, Voltage Control Box, and Logic Box external control devices (see Remote Control
Bus for more information).
Power Entrance: The Power Entrance provides connection for the appropriate power cord (included
with unit). An internal universal switching power supply accepts 100~240VAC @ 50/60Hz, with a
maximum power consumption of 65 Watts.
47
Front Panel Indicators: The Front Panel Indicators (I/O, Com, & Status) are 2-color LEDs.
The following table lists their behavior:
All LEDs green
Normal operating state. Configuration was successful (if applicable).
Device is in a stable state awaiting commands.
I/O LED red
Internal audio hardware error.
Com LED red
Serial Port error.
Ethernet error.
CAN Bus error.
No IP address defined (cleared by setting IP address).
Status LED red
Configuration error.
Last configuration unsuccessful (cleared by 'reset/initializing' the device).
Operating systems resource error.
File system error.
DSP error.
All LEDs blinking
Operating system is not executing. Device must be power cycled.
Status LED blinking
The firmware has attempted to perform an illegal operation. Device must
be power cycled.
48
Control Dialogs
CS Input 10 Channel
NEXIA CS hardware is always represented in the Layout as two separate blocks, one
for input connections and one for output connections. Between these blocks can be
placed virtually any of the other available NEXIA mixing, routing, and processing
blocks (component objects). Like other component objects, NEXIA CS blocks can be
placed into the Layout either from the Processing Library or from the Object Toolbar.
To access Input 10 Channel settings, double-click over the corresponding block in
the Layout. This opens a Control Dialog Box which provides all available settings.
Device IO indicates which hardware input
is associated with that software channel.
Gain In compensates for different input
levels (mic or line), and should be set so
Peak In flashes only occasionally (6dB
headroom). Phan Pwr assigns +48 Volt
phantom power to the input for condenser
microphones. Mute In turns the input
signal on/off. Level (dB) In adjusts the
relative input volume. Invert In reverses
the polarity of the input signal.
Right-clicking over certain settings will
provide a menu of additional options.
Each NEXIA CS comes pre-configured
from the factory with a default system
design. If you wish to load your own
custom designed configuration you will
need to reset/initialize the unit(s) first.
49
CS Output 6 Channel
NEXIA CS hardware is always represented in the Layout as two separate blocks,
one for input connections and one for output connections. Between these blocks

Each channel of AEC has an Advanced dialog box. ERL (Echo Return Loss) shows the level difference
between a signal at the speaker output (AEC Ref) and that same signal as picked up at the mic (AEC
Input). ERLE (Echo Return Loss Enhancement) indicates the amount of processing being applied on that
channel. TER (Total Echo Reduction) shows the combined echo reduction achieved by acoustic damping
(ERL) and signal processing (ERLE). Nonlinear Processing provides additional echo cancellation, for
more challenging applications. However, increased Nonlinear Processing can also adversely affect fullduplex operation. Ref, Mic, and Out display levels at the AEC Ref block and at the AEC block (pre &
post AEC respectively). Echo Detect indicates AEC in progress. Echo Path Changed indicates AEC
converging. Min Threshold prevents AEC re-convergence due to momentarily low levels (such as muted
mics).

produce the control dialog for the associated VC – AEC Input 8 Channel block.
AEC Ref provides the ‘reference’ signal for the associated AEC input channels. This reference is the
signal that AEC will cancel at the corresponding input. In conferencing applications, AEC Ref blocks
should typically receive 'far-end' (Codec In) and ‘program’ signals only (not microphones), and be
connected as close as possible to the output, so as to reflect any level adjustments and signal processing
applied for local sound reinforcement of those same signals. This approach provides the most accurate
reference. AEC Ref blocks should never be connected to paths containing signal from corresponding
AEC Inputs.

Control Dialogs
TC - AEC Input 8 Channel
NEXIA TC hardware is represented in the Layout with as many as ten separate
blocks. Between these blocks can be placed virtually any of the other available
NEXIA mixing, routing, and processing blocks (component objects). Like other
component objects, NEXIA TC blocks can be placed into the Layout either from
the Processing Library or from the Object Toolbar. To access TC – AEC Input 8
Channel settings, double-click over the corresponding block in the Layout. This
opens a Control Dialog Box which provides all available settings.
Device IO indicates which hardware input is associated with that software channel. Gain In
compensates for different input levels (mic or line), and should be set so Peak In flashes only
occasionally (6dB headroom). Phan Pwr assigns +48 Volt phantom power to the input for condenser
microphones. Mute In turns the input signal on/off. Level (dB) In adjusts the relative input volume.
Invert In reverses the polarity of the input signal. AEC turns on/off acoustic echo cancellation. Adv
opens an Advanced dialog. Noise Reduction In selects the amount of background noise reduction to be
applied (6~15dB).
69
Each channel of AEC has an Advanced dialog box. ERL (Echo Return Loss) shows the level difference
between a signal at the speaker output (AEC Ref) and that same signal as picked up at the mic (AEC
Input). ERLE (Echo Return Loss Enhancement) indicates the amount of processing being applied on that
channel. TER (Total Echo Reduction) shows the combined echo reduction achieved by acoustic damping
(ERL) and signal processing (ERLE). Nonlinear Processing provides additional echo cancellation, for
more challenging applications. However, increased Nonlinear Processing can also adversely affect fullduplex operation. Ref, Mic, and Out display levels at the AEC Ref block and at the AEC block (pre &
post AEC respectively). Echo Detect indicates AEC in progress. Echo Path Changed indicates AEC
converging. Min Threshold prevents AEC re-convergence due to momentarily low levels (such as muted
mics).
Right-clicking over certain settings will provide a menu of additional options.
Each NEXIA TC comes pre-configured from the factory with a default system design. If you wish to load
your own custom designed configuration you will need to reset/initialize the unit(s) first.
TC - AEC Ref 8 Channel
NEXIA TC hardware is represented in the Layout with as many as seven separate
blocks. Between these blocks can be placed virtually any of the other available
NEXIA mixing, routing, and processing blocks (component objects). Like other
component objects, NEXIA TC blocks can be placed into the Layout either from
the Processing Library or from the Object Toolbar. The TC – AEC Ref 8 Channel
block has no control dialog of its own. Double-clicking this block in the Layout will
produce the control dialog for the associated TC – AEC Input 8 Channel block.
AEC Ref provides the ‘reference’ signal for the associated AEC input channels. This reference is the
signal that AEC will cancel at the corresponding input. In conferencing applications, AEC Ref blocks
should typically receive 'far-end' (Receive) and ‘program’ signals only (not microphones), and be
connected as close as possible to the output, so as to reflect any level adjustments and signal processing
applied for local sound reinforcement of those same signals. This approach provides the most accurate
reference. AEC Ref blocks should never be connected to paths containing signal from corresponding
AEC Inputs.

TC - Pre-AEC 8 Channel
NEXIA TC hardware is represented in the Layout with as many as seven separate
blocks. Between these blocks can be placed virtually any of the other available
NEXIA mixing, routing, and processing blocks (component objects). Like other
component objects, NEXIA TC blocks can be placed into the Layout either from
the Processing Library or from the Object Toolbar. To access TC – Pre-AEC 8
Channel settings, double-click over the corresponding block in the Layout. This
opens a Control Dialog Box which provides all available settings.
When placing a Nexia TC into the Layout, the TC – Pre-AEC 8
Channel block is optional. It provides the same set of input
signals as the TC - AEC Input 8 Channel block. However, the
signals are derived from the input preamp directly, and are not
affected by AEC or Noise Reduction processing. Pre-AEC input
signals can be used to feed ‘local’ outputs, while the AEC input
signals are used to feed the ‘far end’ (Transmit).
Device IO indicates which hardware input is associated with that
software channel. Peak In should flash only occasionally (6dB
headroom), as determined by AEC Input Gain In settings. Mute
In turns the input signal on/off. Level (dB) In adjusts the relative
input volume. Invert In reverses the polarity of the input signal.
Right-clicking over certain settings will provide a menu of
additional options.

\Telephone Interface
The NEXIA TC Telephone Interface provides connection and control via a standard analog telephone
line and a desk-set station (see TC Hardware). The Telephone Interface is represented by as many as
five separate blocks, as determined during placement into the Layout via the Object Toolbar. Two
primary blocks represent the audio Receive and Transmit functions. Three optional control blocks may
be added individually at any time, representing functions for Dialer, DTMF Decode, and Control/Status.
The Receive block provides an output mix of incoming audio and internal ring
tone signals. Also, a Hook Switch (HS) control input node allows manual
answering of incoming calls, and a Ring indication (RI) control output node
provides indication of incoming calls.
Double-clicking the Receive block produces a control
dialog box.
Device IO indicates which hardware connection is
associated with that software block. Auto Answer
selects the number of rings (or OFF) for automatic
answering of incoming calls. Input provides level
adjustment and muting of incoming audio signals. Ring
provides level adjustment of the internal ring tone signals
for incoming calls. Noise Suppression enables
cancellation of telephone line noise.
72
The Transmit block provides an input connection for outgoing audio signals.
Double-clicking the Transmit block produces a control dialog box.
Device IO indicates which hardware connection is associated with that
software block. Output provides level adjustment and muting of outgoing
audio signals.
The Dialer block provides several control input nodes: nodes
1~16 trigger corresponding speed-dial numbers; Rdl triggers
redial of last number; HF triggers hook flash; and DM selects
pulse dial mode (not currently supported). A control output node
(D) provides indication of dialing in progress.
Double-clicking the Dialer block produces a control dialog box.
Device IO indicates which hardware input is associated with that software channel. Keypad (1~#)
allows number entry via computer mouse. A text box below the Keypad displays the number entry, and
allows number entry via computer keyboard ("," = pause). Clear deletes the current number. Send
dials the current number and becomes End for terminating the call. Tone/Pulse selects the dialing
mode. Flash produces a hook flash on an active line. Identifier allows custom labeling for line
identification. Last Number Dialed displays the number for the previous outgoing call. Redial dials
Last Number Dialed. Caller ID displays the number from the current (or last) incoming call. Idle
changes to indicate call progress, while the adjacent LED indicates an active line. Buttons 1~16 initiate
speed-dialing.
73
Right-clicking over buttons 1~16 provides a dialog
box for entering speed-dial numbers and labeling.
Double-clicking over a previous entry will allow
editing.
A Dialer control dialog box can be minimized to
create a user control surface (see Customizing
Component Objects).
The DTMF Decode block provides several control output nodes:
nodes 1~D provide indication of corresponding DTMF tones;
Any provides indication of any tones.
Double-clicking the DTMF Decode block produces a control
dialog box. Device IO indicates which hardware connection is
associated with that software block. DTMF Decode enables
decoding. Decoded Data displays the characters associated
with the tones.
The Control/Status block provides several control output
nodes: HS indicates hook switch OFF condition; DTD
indicates dial tone detected; BTD indicates busy tone
detected; RTD indicates ring tone detected; LR indicates
line ready (connected); LIU indicates line in use (by other
extension); LI indicates line intrusion (by other extension);
LF indicates line fault condition (may require service).
Double-clicking the Control/Status block produces a
control dialog box. Device IO indicates which
hardware connection is associated with that software
block. Auto Disconnect provides three methods of
call termination (the method used depends on the farend equipment). Loop Drop detects interruptions in the
current of the telephone circuit, Call Progress detects a
special tone indicating call termination, and some farend equipment may use a combination of Loop Drop +
Call Progress. NOTE: Auto Disconnect reliability may
be affected by intermittent line interruptions or cellular
calls. Line displays voltage, current, and fault
conditions on the line.
NOTES: Before compiling, a Country must be designated in the Receive block Property Sheet. For
protection of privacy, the Last Number Dialed and Caller ID displays (on the Dialer control dialog box)
can be disabled via the Control/Status block Property Sheet. Sidetone Level can be set via the Dialer
block Property Sheet.
74
TC Default Configuration
Teleconference System
Each Nexia device comes pre-configured from the factory with a default system design. The factory
default configuration for a NEXIA TC is a 'teleconference system' with 8 automixer AEC mic inputs, 2
program line inputs, and a telephone input feeding a matrix to 4 outputs and a telephone output (see
design layout below). This "TC Default Configuration.NEX" file can be found under Sample Files on the
NEXIA software CD. If you wish to load your own custom designed configuration you will need to
reset/initialize the unit(s) first.
75
Nx
NexLink
Up to four NEXIA devices may be linked
together to share digital audio signals. Tx on
one NEXIA device is connected to Rx on the
next device, using standard 'straight-through'
CAT5 cabling, with a maximum recommended
length of 5 meters per cable.
When multiple NEXIA devices are placed in
the Layout, NexLink blocks become available
for routing digital audio between linked
devices. As NexLink blocks are placed into
the Layout, a dialog box appears for
establishing links between specific devices.
A device can transmit up to sixteen channels
of digital audio to any other single device in
the system. A device can also receive up to
sixteen channels of digital audio from any
other single device in the system.
NexLink is always represented in the Layout
as two separate blocks, one for output
connections (from transmitting device) and
one for input connections (to receiving device).
Signals received by one device may be mixed
and processed as desired, then passed on to
another device, using a separate set of
NexLink blocks. NexLink transmissions are
unidirectional, however, signals will pass
through other devices to reach the destination
device. A complete circuit may be created
between devices by connecting the final
device back to the first (see diagram to left).
76
NOTE: Double-clicking a NexLink In
block provides a Link Status indicator.
This indicator will be green only when
communicating with devices that have
appropriate NexLink cabling in place.
Mixers
These Component Objects provide typical audio mixing functions, in five categories: Standard Mixers;
Matrix Mixers; Auto Mixers; Mix-Minus Combiners; and Room Combiners. Mix-Minus Combiners are
provided to enhance the capabilities of Auto Mixers in mix-minus and input expansion applications.
Room Combiners are provided to enhance the capabilities of Auto Mixers in room combining and zone
routing applications. Mixers are available in pre-defined configurations, however, the configuration
may be customized when being placed from the Object Toolbar.
Once a Component Object is placed into the Layout, all available settings can be accessed by doubleclicking over the object. This produces a Control Dialog Box, which displays the component controls in
a more conventional user interface.

Control Dialogs
Auto Mixers
Mute In turns the input signal on/off. Level In adjusts the
relative input volume. Ch / Bus assigns inputs to the
output. Mute Out turns the output signal on/off. Level
Out adjusts the relative output volume.
Right-clicking over certain settings will provide a menu of
additional options. Unlike other components, Mixers
allow labeling of inputs/outputs within their dialog boxes.
See Channel Identifier under Object Property Sheet.
Mic Options opens a separate control dialog box to
establish global settings.
Designated Mic On / Last Mic Hold determines which
microphone (if any) will stay/become active when no signal is
present. Logic Outputs Follow Mic Logic assigns logic
outputs to follow Designated Mic On / Last Mic Hold. Open
Mic Limits enables (and designates) a maximum allowable
number of active microphones.
Right-clicking over Ch / Bus assignments allows selection of
two additional dialog boxes.
Channel Settings affects individual channel settings, but
may be applied to all channels. Manual turns on/off channel
gating. NOM Gain turns on/off channel contribution to NOM
(number of open mics) attenuation. Direct Output
designates channel direct output signal as Post Gate / Pre
NOM, Post Gate / Post NOM, or Off. (Direct Outputs must
be enabled when placing Auto Mixers from the Object
Toolbar.) Set All causes current Channel Settings to be
applied to all channels. Off Attenuation determines the
amount of attenuation applied when channel is inactive.
Gate Hold Time determines length of time before channel
becomes inactive, once signal is no longer present.
Logic Outputs affects individual Logic Output settings, but may
be applied to all Logic Outputs. (Logic Outputs must be
designated when placing Auto Mixers from the Object Toolbar).
Logic Output selects Follow Gate, On, or Off condition of the
Logic Output. Invert reverses operation of the Logic Output (off
when channel active). Set All causes current Logic Output
settings to be applied to all channels.
78
Standard Mixers
Mute In turns the input signal on/off. Level In adjusts the
relative input volume. Ch / Bus assigns inputs to specific
outputs. Mute Out turns the output signal on/off. Level
Out adjusts the relative output volume.
Right-clicking over certain settings will provide a menu of
additional options. Unlike other components, Mixers
allow labeling of inputs/outputs within their dialog boxes.
See Channel Identifier under Object Property Sheet.
Matrix Mixers
Mute In turns the input signal
on/off. Level In adjusts the relative
input volume. Ch / Bus assigns
inputs to specific outputs, and
right-clicking allows level
adjustment. Mute Out turns the
output signal on/off. Level Out
adjusts the relative output volume.
Matrix Mixers w/Delay are also
available. Mix Table assigns Ch /
Bus to affect either level or delay
settings.
Right-clicking over certain settings will provide a menu of additional options. Unlike other components,
Mixers allow labeling of inputs/outputs within their dialog boxes. See Channel Identifier under Object
Property Sheet.
Mix-Minus Combiners
Mix-Minus Combiners are provided to enhance the capabilities of Auto
Mixers in mix-minus and input expansion applications. Mix-Minus Combiners
combine control data only and, therefore, have no audio outputs. Inputs to a
Mix-Minus Combiner come from outputs of separate Auto Mixers. Ch /
Combine allows input channels (1, 2, 3 etc.) to be grouped into specific
combinations (A, B, C, etc.). These combinations automatically determine
proper routing of control data for the Auto Mixers. Control data represents
NOM (number of open mics) and ATS (adaptive threshold sensing)
information. Mix-Minus Combiners are used when the Auto Mixer outputs
are also connected to a separate Matrix Mixer (to create multiple 'mix-minus'
outputs). Also, Mix-Minus Combiners allow large Auto Mixers to be created
from multiple, smaller ones. This is useful when more than 32 inputs are
required, or when an Auto Mixer must be placed into multiple NEXIA units
(for proper DSP allocation or for physical location of inputs).
Right-clicking over certain settings will provide a menu of additional options.
79
Room Combiners
Room Combiners are provided to enhance the capabilities of Auto Mixers in room combining and zone
routing applications. Room Combiners automatically determine proper routing of audio signals &
control data for the Auto Mixers. Control data represents NOM (number of open mics) and ATS
(adaptive threshold sensing) information. Room Combiners are available only from the Object Toolbar
(not from the Processing Library).
When a Room Combiner is placed,
an Initialization Properties dialog
box appears for creating physical
relationships between rooms. The
overall space is first defined by leftclicking multiple squares (noncontiguous rooms are allowed).
Right-clicking then provides a
menu of additional options, such
as Merge adjacent squares into
larger rooms, and Isolate rooms
which have no moveable partitions.
Enable Control Inputs provides
the Room Combiner with control
nodes, which allow combining via
external devices (see Controls).
Once a Room Combiner is placed, the Control Dialog Box is
available, which displays the overall space, including zones,
partitions, levels, and mutes. Moveable partitions are numbered
relative to control input nodes on the block. Combining may be
accomplished 'automatically' by manipulation of these partitions.
Moveable partitions can be opened/closed by means of external
controls (see Controls & RS-232/Telnet). Combining can instead be
accomplished by recalling stored preset configurations. Preset
configurations must first be created, then recalled through either a
Software User Interface or external controls (see Controls & RS232/Telnet).
The Room Combiner dialog box allows rooms to be combined in
groups, which are color-coded and numbered for identification. This
can be used for real-time software control, or to generate various
configurations to be stored as presets. Rooms can be grouped by
manipulating partitions (using the mouse), or by selecting multiple
rooms while holding Shift or Ctrl. This last approach allows noncontiguous and isolated rooms to be included in combined groups.
Right-clicking on a room provides a menu of sixteen available
groups. Level and mute adjustments become ganged for all rooms
combined in the same group.
Right-clicking over certain settings will provide a menu of additional options. Control Dialog Boxes for
Room Combiner components can be minimized to create user control surfaces (see Customizing
Component Objects).

Equalizers
These Component Objects provide both graphic and parametric equalization, as well as feedback
suppression. Equalizers may be connected between any components within the Layout, for
applications which require room equalization, tone adjustment, or feedback control. Equalizers are
available in pre-defined configurations, however, the configuration may be customized when being
placed from the Object Toolbar.
Once a Component Object is placed into the Layout, all available settings can be accessed by doubleclicking over the object. This produces a Control Dialog Box, which displays the component controls in
a more conventional user interface.

Right-clicking over the object provides a pop-up menu of options.
Control Dialogs
Parametric Equalizer
Active Band selects the current band to be adjusted. Center Freq. adjusts the center frequency for
the current band. Gain adjusts the amount of cut or boost applied at the center frequency for the
current band. Bandwidth adjusts the range of frequencies, above & below the center frequency,
which are also affected by the current band. These settings may also be adjusted by dragging the
band controls shown inside the graph. Dragging the white dot affects both Center Freq. & Gain.
Dragging either yellow dot affects Bandwidth. Flatten Band & Flatten All change the band(s) Gain to
'0' (flat). Bypass Band & Bypass All disable the band(s) without changing settings. Drag Points
turns on/off the band controls, revealing the resultant curve only. Band highlights the current band
inside the graph.
Right-clicking over certain settings will provide a menu of additional options.
81
Graphic Equalizer
Active Band selects the current band to be adjusted. Center Freq. displays the center frequency for
the current band. Gain adjusts the amount of cut or boost applied at the center frequency for the
current band. Active Band and Gain may also be adjusted by dragging the band controls shown inside
the graph. The selected band control becomes yellow, and dragging it up/down affects Gain for that
band. Flatten Band & Flatten All change the band(s) Gain to '0' (flat). Bypass Band & Bypass All
disable the band(s) without changing settings. Drag Points turns on/off the band controls, revealing
the resultant curve only.
Right-clicking over certain settings will provide a menu of additional options.
82
Feedback Suppressor
Feedback Suppressors behave like automatic cut-only parametric equalizers. They utilize 'floating'
bands of equalization which detect and remove feedback frequencies.
Active Band selects the current band for which settings will be displayed. Center Freq. displays the
center frequency for the current band. Gain displays the amount of cut applied at the center frequency
for the current band. Bandwidth displays the range of frequencies, above & below the center
frequency, which are also affected by the current band. Float Limits restricts all floating bands to a
selected maximum depth (cut) and bandwidth (Narrow = 1/40-octave; Wide = 1/10-octave). Reset All
temporarily returns the gain of all floating bands to 0dB (flat). Fix Band & Fix All allow the band(s) to
become manually adjustable (non-floating). Bypass Band & Bypass All disable the band(s) without
changing settings. Drag Points turns on/off the band controls, revealing the resultant curve only.
Band highlights the current band inside the graph. Band Utilization Count indicates the quantity of
floating bands currently being employed.
NOTE: Feedback Suppressors are fairly intensive in their use of DSP resources. They are limited to a
maximum of sixteen bands, however, in most applications the number of actual bands used should be
significantly less. Fixed bands in a Feedback Suppressor may be copied to a Parametric Equalizer.
When applicable, this may be a more DSP efficient choice.
Right-clicking over certain settings will provide a menu of additional options.

All-Pass Filter
All-Pass Filters are so named because they do not affect frequency response. Instead, they affect
signal phase only and, therefore, can be used to compensate for the phase anomalies caused by
normal equalization filters. All-Pass Filters are available with up to sixteen bands.
Active Band selects the current band to be adjusted. Center Freq. adjusts the center frequency for
the current band. Bandwidth adjusts the range of frequencies, above & below the center frequency,
which are also affected by the current band. These settings may also be adjusted by dragging the
band controls shown inside the graph. Dragging the white dot affects Center Freq. Dragging either
yellow dot affects Bandwidth. Add Band & Remove Band work within the designated number of
bands for the filter. Bypass Band & Bypass All disable the band(s) without changing settings. Drag
Points turns on/off the band controls, revealing the resultant curve only. Band highlights the phase
response of the current band inside the graph.

Ducking Level determines how much attenuation is applied to
the normal audio signal during ducking. Attack determines how
quickly the ducker reacts to trigger input (signal or logic).
Release determines how quickly attenuation is released, once
trigger input is removed (signal or logic). Logic In turns on/off
and reverses operation (off triggers ducking) of the logic trigger
input, which appears at the top of the Ducker. Logic Out
provides the same functions as Logic In, but instead as a trigger
output (follows ducking activity), which appears at the bottom of
the Ducker. Mix Sense allows the Sense input signal to be
mixed with normal audio input signal, at the output of the
Ducker. Bypass disables the Ducker without changing
settings.
Right-clicking over certain settings will provide a menu of
additional options.
90
Noise Gate
Noise Gates provide automatic muting, until triggered by
signal presence. Attack Time determines how quickly the
gate opens when signal is present. Release Time
determines how quickly the gate closes when signal is no
longer present. Threshold determines what input signal
level will trigger the gate to open. A meter & numeric display
indicate the amount of gain reduction. Identifier provides a
custom label, when dialog box is minimized (see below).
Bypass disables the Noise Gate without changing settings.
Right-clicking over certain settings will provide a menu of
additional options. Control Dialog Boxes for Noise Gates
can be minimized to create user control surfaces (see
Customizing Component Objects).
Ambient Noise Compensator
Ambient Noise Compensators automatically adjust program volume in response to changes in
background noise levels, as monitored by external ambient sensing microphone(s). Program Mute
turns the program input signal on/off. Program Level adjusts the relative program input volume.
Program Label provides a custom label, when the dialog box is minimized (see below). Prog Meter
displays the current program input level. Ambient Mute turns the ambient input signal on/off.
Ambient Level adjusts the relative ambient input volume. Ambient Threshold determines the
ambient noise level at which program gain increases will begin. Ambient Response sets the period of
time to be considered when calculating an average of ambient level changes. Ambient Label
provides a custom label, when the dialog box is minimized (see below). Amb Meter displays the
current ambient input level. The Set Threshold button can be used to estimate an appropriate
Ambient Threshold setting. Gain Min sets the minimum output gain (for periods of low ambient noise).
Gain Max sets the maximum output gain (for periods of high ambient noise). Gain Ratio determines
how much the program volume will increase, relative to a given increase in ambient noise. Gain Time
establishes how quickly program gain changes are applied. Gain Time indicates the amount of time
required for a gain change between Min and Max settings. Lesser gain changes will occur more
rapidly. Gain Meter displays the current gain compensation being applied. Bypass disables the
Ambient Noise Compensator without changing settings.
Right-clicking over certain settings will provide a menu of additional options. Control Dialog Boxes for
Ambient Noise Compensators can be minimized to create user control surfaces (see Customizing
Component Objects).

ANC Setup Procedure
Connections
•
Feed the "program" signal into the Program Input (top left) of the ANC block. Setup of the ANC
block is best done with a relatively constant program source. This can be the actual program
source or a pink noise approximation, but its level should represent the highest program material
level you expect will be fed to the ANC block.
•
Feed the "ambient" signal into the Ambient Input (bottom left, marked with an "A") of the ANC
block. This signal should be derived from either a single dedicated sensing microphone, or from
a dedicated array of sensing microphones feeding a common Mixer block. Setup of the ANC
block is best done when the ambient noise in the room(s) is minimal, but the Ambient Meter
should read at least -60dBu.
•
Connect the output of the ANC block to its destination. Keep in mind that the ANC should be the
last block in the program signal path, with no form of level control provided at the outputs,
amplifiers, or speakers.
Setting Min and Max Gain
•
Adjust the Min Gain and Max Gain settings for the desired amounts of minimum and maximum
gain to be applied to the program signal. Remember that Min Gain is the constant gain that the
ANC block will apply while the Ambient Input signal level is below the Ambient Threshold.
Remember that Max Gain is the maximum amount of gain that the ANC block will ever apply to
the program input.
If Min Gain and Max Gain are not known, these settings may be determined by listening to the ANC
output, as follows:
•
Set the Ambient Threshold to its maximum setting (+24dBu) to ensure the Ambient Input level is
below threshold. This ramps the ANC to the Min Gain setting. Keep in mind that the speed of
this ramping is determined by the Gain Time setting.
•
Adjust Min Gain until you have the desired minimum program level comining out of the ANC
block. Note this value for later.
•
Adjust Min Gain until you have the desired maximum program level coming out of the ANC block.
Set Max Gain to this value. Set Min Gain to the value determined in the previous step.
Setting Response Times
•
Adjust the Gain Time to determine how quickly the ANC gain changes. Gain Time is the amount
of time it takes for the ANC block to ramp from Gain Min to Gain Max, or vice versa.
•
Adjust the Ambient Response time to determine how quickly the Ambient Input detector responds
to changes in the Ambient Input signal. Ambient Response should be set fast enough to track
important ambient level changes (e.g. an approaching train in a depot), but slow enough to ignore
unimportant ambient level changes (e.g. someone popping their bubble gum).
Note: The overall responsiveness of the ANC output is determined by the larger (slower) of the two
aforementioned times: Gain Time and Ambient Response time.
Setting Thresholds
•
Press the "Set Threshold" button, ensuring that the Program Input level is a good approximation
of the highest program signal level you expect will be fed to the ANC. This process records the
levels of both the Ambient and Program inputs. The Ambient Threshold is set to 10dBu higher
than the recorded Ambient level. This process takes up to 5 seconds.
Set Gain Ratio
•
92
Adjust Gain Ratio to specify how many dB of gain is applied for every dBu over Ambient
Threshold the Ambient level is.
Routers
These Component Objects provide typical audio routing functions. Routers may be connected
between any components within the Layout, for applications which require routing of input signals to
various outputs. Routers are available in pre-defined configurations, however, the configuration may
be customized when being placed from the Object Toolbar.
Once a Component Object is placed into the Layout, all available settings can be accessed by doubleclicking over the object. This produces a Control Dialog Box, which displays the component controls in
a more conventional user interface.
see Router Control Dialog
Right-clicking over the object provides a pop-up menu of options.
Control Dialogs
Router
Routers allow each input to be assigned to multiple outputs via In / Out.
However, each output allows only one input assigned at a time. Therefore,
Routers behave like a series of individual distribution amplifiers. For
increased input/output assignment capability, see Mixers.
Right-clicking over certain settings will provide a menu of additional options.
Delays
These Component Objects provide typical audio time-delay functions. Delays may be connected
between any components within the Layout, for applications which require room delay and/or
loudspeaker time-alignment.
Once a Component Object is placed into the Layout, all available settings can be accessed by doubleclicking over the object. This produces a Control Dialog Box, which displays the component controls in
a more conventional user interface.

Delay
Value determines the amount of delay, based on
the selected Units. Units selects either time
(milliseconds) or distance (meters, centimeters,
feet, or inches). Bypass disables the Delay without
changing settings.
Right-clicking over certain settings will provide a
menu of additional options.
Controls
These Component Objects provide both internal and external control functions. Level Controls, Mute
Buttons, and Invert may be connected between components within the Layout, for control of volume,
muting, and polarity. Preset and Remote Preset Buttons may be placed within the Layout, and defined
to recall specified Presets. Logic Gates and Logic Delay may be connected between component
control nodes in the layout, to customize control behavior. Command Strings can provide serial control
of external devices, when triggered by control nodes on other components in the layout. Volume 8,
Select 8, Volume/Select 8, Voltage Control Box, and Logic Box components may be placed within the
layout, to represent their corresponding external control devices. Controls are available in pre-defined
configurations, however, the configuration may be customized when being placed from the Object
Toolbar.
Once a Component Object is placed into the Layout, all available settings can be accessed by doubleclicking over the object. This produces a Control Dialog Box, which displays the component controls in
a more conventional user interface.

Control Dialogs
Level
Mute turns on/off the channel. Channel level may be
entered numerically, or may be adjusted by dragging
the fader. Maximum and Minimum can be used to
restrict the range of level adjustment provided by the
fader. Level ID provides a custom label, when the
dialog box is minimized (see below).
Right-clicking over certain settings will provide a menu
of additional options. Control Dialog Boxes for Level
Control components can be minimized to create user
control surfaces (see Customizing Component
Objects).
When placed from the Object Toolbar, multiple Level
Controls may be 'ganged' together onto a single fader.
Ganged Level Controls display a 'G' in the upper-right
of the Component Object, and Level ID colors are
reversed on the Control Dialog. Non-ganged Level
Controls have a maximum of 16 channels, whereas
ganged Level Controls have a maximum of 32
channels.
Level Inc/Dec
Level Inc/Dec blocks are identical to Level blocks,
except they also provide control input nodes for making
incremental level changes. Inc/Dec Step determines
the amount of level change to occur each time the
associated control node is triggered. Control input
nodes along the top of the block are labeled as positive
(+) and negative (-). When triggered by control output
nodes on other components within the layout design,
positive nodes produce a single-step increase in level
("Increment") and negative nodes produce a single-step
decrease in level ("Decrement").
When placed from the Object Toolbar, multiple Level
Inc/Dec Controls may be 'ganged' together onto a
single fader. Also, ramping may be enabled at this
time. When ramping is enabled, Inc/Dec Rate sets
timing (mS) between repetitive incremental changes
(Inc/Dec Steps) which occur automatically as long as
the associated control node (+ or -) remains triggered.
95
Invert
Invert reverses the polarity of the audio signal (180°). Identifier provides a
custom label, when the dialog box is minimized (see below).
Right-clicking over certain settings will provide a menu of additional options.
Control Dialog Boxes for Invert components can be minimized to create user
control surfaces (see Customizing Component Objects).
When placed from the Object Toolbar, multiple Invert channels may be
'ganged' together onto a single control. Ganged Invert controls display a 'G' in
the upper-right of the Component Object, and Identifier colors are reversed on
the Control Dialog. Non-ganged Invert controls have a maximum of 16
channels, whereas ganged Invert Controls have a maximum of 32 channels.
Mute Button
Mute turns on/off the channel. Identifier provides a custom label, when the
dialog box is minimized (see below).
Right-clicking over certain settings will provide a menu of additional options.
Control Dialog Boxes for Mute Button components can be minimized to create
user control surfaces (see Customizing Component Objects).
When placed from the Object Toolbar, multiple Mute Buttons may be 'ganged'
together onto a single button. Ganged Mute Buttons display a 'G' in the
upper-right of the Component Object, and Identifier colors are reversed on the
Control Dialog. Non-ganged Mute Buttons have a maximum of 16 channels,
whereas ganged Mute Buttons have a maximum of 32 channels. Also, Mute
Button blocks may be placed with control input nodes selected.
Preset Button
Right-clicking over a button provides a list of available Presets
which can be assigned to that button. The Preset Number will
appear on the button, and the Preset Name will appear to the
right. Preset Numbers can be replaced with the word 'Recall'
(see General Options). Control Dialog Boxes for Preset Button
components can be minimized to create user control surfaces
(see Customizing Component Objects).
Remote Preset Button
Remote Preset Buttons are identical to Preset Buttons, except
they have control input nodes on the block. These control input
nodes allow presets to be recalled via control output nodes on
other component blocks. This provides remote control of preset
selection, both from internal components and external controls.
Unlike most other blocks, multiple control output nodes may be
connected to a single control input node on a Remote Preset
Button. Control Dialog Boxes for Remote Preset Button
components can be minimized to create user control surfaces
(see Customizing Component Objects).
96
Logic Gates
Most Logic Gates have no Control Dialog Boxes. They are used only to customize behavior of other
control functions in the system. Logic Gates are connected between the output and input control
nodes of other components in the layout. These components can represent internal or external control
functions.
Examples
Internal: Auto Mixer output nodes; Ducker input/output nodes; Remote Preset Button input nodes.
External: Select 8 output nodes; Volume/Select 8 output nodes; Logic Box input/output nodes.
Logic Gates alter the normal operation of component control outputs in the following ways:
NOT: produces opposite/inverted operation (input HIGH turns output LOW; input LOW turns output
HIGH).
AND: all inputs HIGH causes output to go HIGH (any inputs LOW causes output to go LOW).
NAND: all inputs HIGH causes output to go LOW (any inputs LOW causes output to go HIGH).
OR: any inputs HIGH causes output to go HIGH (all inputs LOW causes output to go LOW).
NOR: any inputs HIGH causes output to go LOW (all inputs LOW causes output to go HIGH).
XOR: any inputs (except all) HIGH causes output to go HIGH (all inputs LOW / HIGH causes output to
go LOW).
Flip Flop: produces toggle/latching operation (input HIGH changes output state, HIGH / LOW).
Logic State: provides manual latching operation only (includes no input node).
NOTES: NOT and Flip Flop gates have only a single input per output, whereas most other gates have
multiple inputs, up to 8. Flip Flop gates provide a control dialog box, for establishing their initial output
state. Also, unlike most other blocks, multiple control output nodes may be connected to a single
control input node on a Flip Flop gate. Control Dialog boxes for Logic State gates can be minimized to
create user control surfaces (see Customizing Component Objects).
Sample Application
Normally, a Select 8 control output connected to a Ducker control
input provides a momentary operation (ducking occurs only as long
as the Select 8 control is being pressed). However, connecting a
Flip Flop Logic Gate between the Select 8 control output and the
Ducker control input produces a press-on/press-off operation
(ducking begins with the first press of the Select 8 control, and
ceases only upon a second press of the Select 8 control).
97
Logic Delay
Logic Delays are connected between the output and input
control nodes of other components in the layout. These
other components may represent internal or external
control functions. When a change (on/off) occurs at the
Logic Delay input, and remains in that condition beyond
the designated delay time, the Logic Delay output will
then produce that same change..
On sets turn on delay. OFF sets turn off delay. The
range for either selection is 0~60,000mS (1 minute).
Bypass disables the delay without changing settings.
Right-clicking over certain settings will provide a menu of
additional options.
Command String
Command String blocks allow RS-232 control of
external devices via NEXIA's Serial port. Control input
nodes along the top of the block produce corresponding
serial commands, when triggered by control output
nodes on other components within the design.
Commands can also be initiated using the command
button which appears within the control dialog box.
Command ID allows the command/button to be named.
Command String allows the appropriate character
string to be entered. Update sends the character string
to be stored in NEXIA device memory.
Unlike most other blocks, multiple control output nodes may be connected to a
single control input node on a Command String block. Control Dialog Boxes for
Command String components can be minimized to create user control surfaces
(see Customizing Component Objects).
NOTE: Some command strings may need to output nonprintable characters. The strings themselves
must be printable, so this is done by including three-character sequences in the command string. The
first will be a tilde, the second and third hex digits. To include a carriage return and line feed pair, for
example, in the string, include the text ~0d~0a (either case may be used). A tilde may only be included
by using the sequence ~7E (or ~7e) for the tilde character itself.
98
Volume 8
The Volume 8 is an external control device, which allows
adjustment of eight selectable NEXIA volumes. Volumes can
be individual or grouped levels within NEXIA. This includes
Level Control blocks, as well as level adjustments found in the
Control Dialog boxes of other component blocks.
Volume 8 is represented in the layout as a block with no
audio or control connections. All functions are assigned using
the control dialog box. Object Code selects from a list of
blocks found in the layout, and Instance ID is entered
automatically, but both can be found easily using Object ID
Inspector. Control ID selects from a list of available levels
within the chosen block. Volume up/down buttons allow
control of assigned levels directly from the dialog box.
Identifier provides a custom label, when the dialog box is
minimized (see below).
Control Dialog Boxes for Volume 8 components can be
minimized to create user control surfaces (see Customizing
Component Objects).
Volume 8 controls fit most US standard single-gang back-boxes (back-boxes are available separately
from Biamp Systems). Custom Control Labels may be printed for the Volume 8. Please refer to the
'Installation Guide' (included with controls), or see Remote Control Bus for more information. External
controls must be identified (see Device Maintenance) and associated with their corresponding
component blocks within the layout (see Equipment Table).
99
Select 8
The Select 8 is an external control device, which
allows initiation of eight selectable NEXIA actions.
Actions can be individual or grouped functions within
NEXIA. This includes recalling presets, ducking,
combining, etc.
Select 8 components have no Control Dialog Boxes.
They are represented in the layout as a block with
eight control output nodes. These control output
nodes are connected to control input nodes on the
other component blocks to be controlled. These other
components may include Remote Preset Buttons,
Duckers, Room Combiners, and Logic Boxes. Muting
and room combining routines can also be achieved
using presets. Logic Boxes can provide logic outputs
for controlling additional equipment, external to NEXIA.
Select 8 behavior can be altered using Logic Gates.
Select 8 controls fit most US standard single-gang
back-boxes (back-boxes are available separately from
Biamp Systems). Custom Control Labels may be
printed for the Select 8.
Please refer to the 'Installation Guide' (included with
controls), or see Remote Control Bus for more
information. External controls must be identified (see
Device Maintenance) and associated with their
corresponding component blocks within the layout (see
Equipment Table).
100
Volume/Select 8
The Volume 8 is an external control
device, which combines the functions of
both Volume 8 and Select 8 controls.
Therefore, the Volume/Select 8 is
represented with a control dialog box (for
volume functions), as well as a component
block with control output nodes (for select
functions).
Control Dialog Boxes for Volume/Select 8
components can be minimized to create
user control surfaces (see Customizing
Component Objects).
Volume/Select 8 controls fit most US
standard 2-gang back-boxes (back-boxes
are available separately from Biamp
Systems).
Custom Control Labels may be printed for
the Volume/Select 8. Please refer to the
'Installation Guide' (included with controls),
or see Remote Control Bus for more
information. External controls must be
identified (see Device Maintenance) and
associated with their corresponding
component blocks within the layout (see
Equipment Table).
101
Voltage Control Box
The Voltage Control Box (VCB) is an external control
device, which provides four analog potentiometer inputs
and four logic inputs/outputs. When a VCB is placed, an
Initialization Properties dialog box appears for assigning
the quantities of logic inputs/outputs (4 total). Although the
quantity of logic connections on a Voltage Control Box (4)
is different from those on a Logic Box (20), their operation
and behavior are identical. (See Logic Box for further
explanation of logic inputs/outputs).
Once a VCB block has been placed, double-clicking it will produce a dialog for assigning Analog
(potentiometer) controls. A single VCB allows potentiometer adjustment of up to four selectable Nexia
levels. Levels can be individual or ganged levels within Nexia. This includes Level Control blocks, as
well as levels within other component blocks (such as Inputs & Outputs, Mixers, Equalizers, etc.).
Object Code selects from a list of blocks found in the layout, and Instance ID is entered automatically,
but both can be found easily using Object ID Inspector. Control ID selects from a list of available
levels within the chosen block. Identifier provides a custom label for the assigned control.
External controls must be identified (see Device Maintenance) and associated with their corresponding
component blocks within the layout (see Equipment Table). The VCB will assume a full range of 0~5
Volts returning from connected potentiometers, unless the VCB Calibration procedure is followed (see
Device Maintenance). Please refer to the 'Installation Guide' (included with controls), or see Remote
Control Bus for more information.
102
VCB Calibration
Once a VCB (Voltage Control Box) block has been assigned in a Nexia configuration, and the VCB
device (with potentiometers attached) is connected to the Nexia Remote Control Bus, the
potentiometers can be calibrated for accurate tracking of levels (see Device Maintenance).
The first screen encountered in this process allows for the
selection of the potentiometer Channel to be calibrated.
Channel numbers correspond to the Analog potentiometer
connections on the VCB itself. Only one potentiometer
Channel can be calibrated at a time, and only Channels
with potentiometers actually connected will be available.
Once the Channel has
been selected, this
screen will prompt the
user to adjust the
corresponding
potentiometer (on the
selected Channel) to its
maximum (highest)
physical setting, then
select "Next".
Once the maximum
potentiometer setting
has been recorded, this
screen will prompt the
user to adjust the same
potentiometer to its
minimum (lowest)
physical setting, then
select "Next".
When maximum and
minimum potentiometer
settings have both been
recorded, this screen will
indicate the voltage
measurements and
prompt the user to either
accept these values or
re-calibrate. "Finish" will
return to the Channel
selection screen.
NOTE: The entire range of level adjustment assigned to a potentiometer will be controlled by the voltage
range measured during calibration. If the potentiometer is not calibrated, or is calibrated incorrectly,
accurate control of the intended range of levels may not be achieved.
103
Logic Box
The Logic Box is an external control device, which
provides twenty logic input/output connections. When a
Logic Box is placed, an Initialization Properties dialog box
appears for assigning the quantities of logic inputs/outputs
(20 total). Logic inputs allow external switches to initiate
NEXIA actions. Actions can be individual or grouped
functions within NEXIA. This includes recalling presets,
ducking, combining, etc. Logic outputs can be used to
control additional equipment, external to NEXIA.
Logic Box components have no Control Dialog Boxes. They are represented in the layout as a block with
a total of twenty control input/output nodes. Logic Inputs (on the box) are represented as control output
nodes (on the block). These control output nodes may be connected to control input nodes on other
components, such as Remote Preset Buttons, Room Combiners, Duckers, Mute Buttons, and Level
Inc/Dec controls. Logic Outputs (on the box) are represented as control input nodes (on the block).
These control input nodes may be connected to control output nodes on other components, such as Auto
Mixers, Duckers, and Select 8. Unlike other components, Logic Box output nodes may be connected to
input nodes on the same Logic Box block, allowing Logic Inputs (external switches) to control Logic
Outputs (external equipment).
Logic Box behavior can be altered using Logic Gates. Please refer to the
'Installation Guide' (included with controls), or see Remote Control Bus for more
information. External controls must be identified (see Device Maintenance) and
associated with their corresponding component blocks within the layout (see
Equipment Table).
Up to 20 logic inputs are availble on the Logic Box. Logic inputs allow remote control of NEXIA via
external circuits such as switches, relays, and logic outputs from other devices. When nothing is
connected to a logic input, an internal pull-up resistor keeps it at a 'high' state (+5.0 VDC). The logic
input is activated when its input goes 'low' (less than +0.8 VDC), and is de-activated when its input
goes 'high' (greater than +2.0 VDC). A logic input can be controlled in one of three ways: 1) Using an
'open-collector' or 'open-drain' logic output from an external device to short the logic input to ground.
2) Using a switch, relay, or other contact-closure to short the logic input to ground. 3) Using an active
5V TTL output driver circuit (such as from a third-party controller) to actively drive the logic input to a
'high' or 'low' state. Multiple contact-closures or 'open-collector'/'open-drain' logic outputs may be wired
in parallel to a single logic input (see diagram below). Open-collector or open-drain logic outputs and
contact-closures should be rated for at least 5 Volts / 1mA operation. Active output driver circuits
should not exceed a signal range of 0~5 Volts DC, and should have a minimum pulse width of 10 milliseconds. The logic input impedance is approximately 10k ohms.
The Logic Box provides up to 20 logic outputs. Logic outputs can be used to control relays and
indicators or to drive logic inputs of other devices. The Logic Box logic outputs are 'open collector' with
an internal pull-up. Each logic output is an NPN transistor with the collector being the output and the
emitter being ground (see diagram below). When a logic output is turned on, the transistor provides a
path for DC current to flow, lowering the output voltage to below 0.8V. When a logic output is turned
off, the internal pull-up resistor raises the output voltage to near 5V, depending on the output current.
To activate external relays or indicators, an external power supply must be used (see diagram below).
The logic output transistors are rated up to a maximum of 40 VDC and 500 mA per output (24 volt
relay coils maximum). However, +12 Volts DC is sufficient power for most applications. When using
the logic outputs to control relays, protection diodes must be used to suppress high voltage transients
that are generated when the relays turn off (see diagram below).
104
105
Control Labels
The Volume 8, Select 8, and Volume/Select 8 controls all come with a sheet of clear, adhesive-backed
labels, for custom printing on a laser printer. A Word document is available on the NEXIA software CD
and on the Biamp web site (www.biamp.com), as a label printing template. These labels are meant to
be printed using desk-top laser printers only. It is recommended that the printer be set for 'label'
printing, and the label sheet should be 'short-edge' feed from the 'bypass' tray. A test printing of a
single label should be done, to assure proper alignment of text. To compensate for any mis-alignment
of text, margins within the Word document may be adjusted. Care should be taken in placement of the
labels onto the controls. To avoid finger-prints, the use of a knife-blade or tweezers is recommended
for handling. Severe bending or curling of the label may cause loss of some toner (text). When
placing the label on the control panel, use the vertical column of LED indicators as a visual reference of
alignment. Once the label is in place, a second (un-printed) label may be placed over the first label, to
provide protection against wear. Each sheet contains 25 labels, so in case of errors, additional labels
may be printed.
NOTE: Originally, labels were 1.35" wide and used the Word document (V8S8 Labels.doc). However,
newer control panels require labels which are only 1.25" wide and use Word document (V8S8 B
Labels.doc). Check label width and use the appropriate file for printing.
In the Word document, select Show Gridlines from the Table menu. Each large cell represents a label.
The first four columns are 'left-justified' to create labels for Volume 8 and Select 8 panels, as well as for
the 'Volume' (left) section of Volume/Select 8 panels. The last column is 'right-justified' to create labels
for the 'Select' (right) section of Volume/Select 8 panels. Left-click inside any large cell, and begin
typing. Use 'Enter' to begin a new line, and again to leave a blank line. To avoid printing errors, do not
change line-spacing or other formatting parameters. However, if you do not have the default font
(Helvetica), or if you wish to change label appearance, you may select a different font before typing.
106
Meters
These Component Objects provide Signal Present, Peak, RMS, and Logic metering functions. Meters
may be connected to any component output, and may be used for diagnostic and setup purposes, or
for applications which require real-time metering. Meters are available in pre-defined configurations,
however, the configuration may be customized when being placed from the Object Toolbar.
Once a Component Object is placed into the Layout, all available settings can be accessed by doubleclicking over the object. This produces a Control Dialog Box, which displays the component controls in
a more conventional user interface.

These Component Objects provide sine-wave, sweep, pink-noise, and white-noise generator functions.
Generators may be connected to any component input, and may be used for diagnostic and setup
purposes, or for applications which require tones or sound-masking.
Once a Component Object is placed into the Layout, all available settings can be accessed by doubleclicking over the object. This produces a Control Dialog Box, which displays the component controls in
a more conventional user interface.

see Pink Noise Generator Control Dialog
see White Noise Generator Control Dialog
Right-clicking over the object provides a pop-up menu of options.
Control Dialogs
Tone Generator
Tone selects a single frequency. Sweep selects a range
of frequencies (instead of a single tone). Mute turns
on/off the generator. Level determines the generator
output level. Frequency determines the frequency for
Tone. Start Frequency & Stop Frequency determine
the range of frequencies for Sweep. Frequency Interval
selects the spacing (and quantity) of individual tones for
Sweep. Time Interval determines the time each tone is
held for Sweep.
Right-clicking over certain settings will provide a menu of
additional options.
Pink Noise Generator
Mute turns on/off the generator. Level determines generator output level.
Right-clicking over certain settings will provide a menu of additional options.
White Noise Generator
Mute turns on/off the generator. Level determines generator output level.
Right-clicking over certain settings will provide a menu of additional options.
109
Diagnostics
These Component Objects provide Transfer Function displays for diagnostic purposes. Transfer
Function may be connected between any two component outputs on the same signal path, for a
comparative analysis of processing.
Once a Component Object is placed into the Layout, all available settings can be accessed by doubleclicking over the object. This produces a Control Dialog Box, which displays the component controls in
a more conventional user interface.
see Transfer Function Control Dialog
Right-clicking over the object provides a pop-up menu of options.
Control Dialogs
Transfer Function
Transfer Function may be connected between any two component outputs on the same signal path, for
a comparative analysis of processing. Gain displays the difference in frequency response between the
two comparison points, as a white line. Phase displays the phase relationship between the two
comparison points, as a green line. Unwrap removes out-of-range phase rotations from the phase
display. Delays adds the effect of user-placed delay blocks (Delay and Matrix Mixer w/ Delay) into the
phase display. The Phase display does not indicate inherent propagation delay within the system.
Propagation delay is indicated separately at the bottom of the dialog box (1/3mS hops, if not
compiled...or...real-time including equalization delay, if compiled). When a Transfer Function dialog
box is open, the associated signal path is indicated as a dashed red line in the layout.
110
Specialty
These Component Objects provide Pass-Through and Split Pass-Through functions, to aid in the
organization of system connections. Pass-Through blocks allow wiring nodes to be strategically
placed, so audio or control (logic) signals can be routed in different directions. Split Pass-Through
blocks allow associated input and output wiring nodes to be placed in separate locations, with an
implicit or 'wireless' connection being maintained between them.
Pass Through and Split Pass Through blocks simply allow custom signal routing, and provide no actual
processing of their own. Therefore, they do not have Control Dialog Boxes. Instead, an Initialization
Properties window appears, for component definition and customization, when these blocks are placed
into the Layout.

Pass-Through
Pass-Through blocks allow wiring nodes to be
strategically placed, so audio or control (logic)
signals can be routed in different directions.
Type selects whether the block is for audio or
logic connections. Channel Count selects the
quantity of input/output connections to be
provided on the block. Signal In determines the
physical location of input wiring nodes on the
block. Signal Out determines the physical
location of output wiring nodes on the block.
Pass-Through blocks allow custom signal routing
and labeling, but provide no actual signal
processing. APT stands for Audio Pass-Through.
LPT stands for Logic Pass-Through. This example
shows a pair of 2-channel Audio Pass-Through
blocks used to create a double-bend.
111
Split Pass-Through Input
Split Pass-Through blocks allow associated input and
output wiring nodes to be placed in separate locations,
with an implicit or 'wireless' connection being
maintained between them.
Type selects whether the blocks are for audio or logic
connections. Channel Count selects the quantity of
input/output connections to be provided on the blocks.
Separate 'Link-In' and 'Link-Out' blocks are placed for input and output connections. Wiring nodes
appear on the left side of input blocks and on the right side of output blocks. Link-In and Link-Out
blocks are also numbered to identify their association. More than one Link-Out block can be placed in
association with an existing Link-In block (see Split Pass-Through Output).
Split Pass-Through blocks allow custom signal routing
and labeling, but provide no actual signal processing.
APT stands for Audio Pass-Through. LPT stands for
Logic Pass-Through. This example shows a 2-channel
Audio Split Pass-Through.
Split Pass-Through Output
More than one Link-Out block can be placed in
association with an existing Link-In block (see Split
Pass-Through Input).
Object Code of Input Link to Associate With selects
which existing Link-In block the new Link-Out block
should be associated with. The new Link-Out block will
include the appropriate number of output wiring nodes,
and the same numbered association, as other Link-Out
blocks already associated with the selected Link-In
block. Additional Link-Out blocks allow a single set of
input connections to be distributed to multiple sets of
output connections.
Pass-Through blocks allow custom signal routing and
labeling, but provide no actual signal processing. APT
stands for Audio Pass-Through. LPT stands for Logic
Pass-Through. This example shows an existing 2channel Audio Split Pass-Through with an additional 2channel Link-Out block.

113
System Design
Placing Component Objects
System design begins with the placement of Component Objects into the Layout. This can be done in
two ways. The simplest way is to select a component category from the Processing Library, and then
drag & drop a pre-defined component into the Layout. Processing Library component categories can
also be selected from the Processing Library Menu (at the top of the screen), which indicates keyboard
short-cuts as well. However, component placement can instead be done using the Object Toolbar,
located directly above the Layout. On the Object Toolbar, next to each category icon is a drop-down
menu of components. Selecting a component from the menu, then clicking over the Layout, will place
the selected component at that location. Holding the Shift key allows multiple copies of the component
to be placed. Certain components will provide a pop-up ‘Initialization Properties’ window, allowing
further component definition and customization before placement. Using the Object Bar also allows
the Processing Library to be closed (providing greater width to the Layout). Component Objects, and
their current settings (DSP data), can also be placed using the Copy/Paste functions on the Standard
Toolbar or the Edit Menu. Selected objects can also be copied by holding the Alt key while dragging
and dropping. NOTE: Components cannot be selected when the current Layer is invisible (see Layers
Sheet).
The configuration of certain components can be further edited, once they have been placed into the
Layout. This can be done even after the design has been compiled, and without affecting the
component Instance ID assignments. Right-clicking over the component block and selecting ‘Edit
Block Parameters’ will again provide access to the Initialization Properties window, where additional
changes to the component configuration may be made. NOTE: Edit Block Parameters is not available
for all component types or configuration properties.
Arranging Component Objects
The physical arrangement of objects within the Layout can be modified in several ways. Objects can
be packed side-by-side, have their edges aligned, be centered in the view, be spaced evenly, and be
made the same size. Objects can also be arranged from front to back, when multiple objects are
overlaid. In addition, objects can be forced to snap to an adjustable grid. See Layout Toolbar and
Layout Menu. Objects within the Layout can also be organized in separate groups called Layers (see
Layers Sheet).
114
Connecting Component Objects
Each Component Object includes Nodes for making system wiring connections. Nodes are provided in
four types, each with a specific location on the Component Object. Audio input Nodes are always on
the left. Audio output Nodes are always on the right. Control (logic) input Nodes are always on the
top. Control (logic) output Nodes are always on the bottom. An exception to these rules is the PassThrough block, which allows wiring nodes to be strategically placed for routing signals in different
directions. When an object (such as a Ducker) includes an audio control (sense) input, it will be below
the normal audio inputs (on the left).
To make a connection, click on a Node, move the mouse to a corresponding Node, and click again to
place a Line Object (wire). Multiple Nodes on one or more objects can be selected as a group (click &
drag to select). Then, by clicking on the top selected Node, these multiple Nodes may be connected to
a matching set of multiple Nodes on one or more other objects, in the same manner as described
previously for a single connection.
Segmented lines, with bend points, may also be drawn by simply clicking in the Layout (instead of on a
destination Node). This produces a bend point, from which additional line segments may be drawn.
Each additional click produces a new line segment, ultimately ending at the destination Node. Bend
points allow a line to include angles, which can be useful in organizing the design. If a mistake is
made while drawing line segments, double-clicking will erase the entire line.
Bend points are normally constrained to the Grid, making it easier to create straight lines and rightangles. When creating right-angles, horizontal audio line segments retain their vertical spacing
(aligned with Nodes/Grid), and vertical line segments form a single bus of overlying lines. However,
with logic line segments, vertical lines retain their spacing and horizontal lines form a single bus. The
positioning of line segments and bend points, on a selected line, may be edited with the following
short-cuts: Line Click = move a line segment; Line Shift-Click = move a line bus; Bend Click = move
a bend point; Line Alt-Click = add a bend point; Bend Shift-Alt-Click = delete a bend point. When
drawing a line: Ctrl = not constrained to Grid; Shift = fan-out connections (single line to multiple
Nodes). An entire Line Object (wire) or individual Node connection can be moved (but not copied).
The appearance & properties of Line Objects (wires) in the Layout, including the ability to add
identifying text to a line, can be changed (see Format Toolbar and Line Property Sheet). Text may be
added or edited on a line by selecting the line and pressing Enter, or by right-clicking on the line and
selecting Edit Text. However, other text attributes must still be addressed via the Property Sheet.
An output Node can be connected to multiple input Nodes, but an input Node cannot be connected to
multiple output Nodes. (NOTE: Exceptions to this rule are the control input nodes of Remote Preset,
Command String, and Flip Flop Gate blocks.) Audio Nodes & Control (logic) Nodes cannot be
connected to each other. Input & Output Nodes on the same object cannot be connected to each
other. (NOTE: An exception to this rule is the control input and control output nodes of a Logic Box or
Voltage Control Box block.) Nodes of the same type (Input or Output) cannot be connected together.
Component Object Properties
Component Object Properties are the control settings available for each component. These represent
the same settings normally found on equivalent analog audio products. Component Object Properties
for a selected component can be viewed/edited (in table form) using the Object Property Sheet. They
can also be copied & pasted (as DSP Data) between components of the same type, using the Edit
Menu. However, once a Component Object is placed into the Layout, all available settings can be
accessed by double-clicking over the object. This produces a Control Dialog Box, which displays the
component controls in a more conventional user interface.
There are several Component Object categories, with some categories providing several component
variations. Each component type will have a unique Control Dialog Box. For more information on
specific components and their Control Dialog Boxes, see Object Toolbar.
115
Customizing Component Objects
Component Objects can be customized in several ways. First, when using the Object Toolbar to place
components into the Layout, certain components will present the user with a pop-up ‘Initialization
Properties’ window of configuration options. Several pre-defined configuration (input/output) options
may be available for the component, as well as a 'custom' selection that allows the user to more
specifically configure the component. Some components (such as Auto Mixers) allow activation of
additional features (such as Logic Inputs & Direct Outputs). Multiple channels of Level, Invert, & Mute
may be 'ganged' onto a single control. Multi-channel Invert and Mute Buttons may be set for
'horizontal alignment' and/or 'no labeling' when minimized as a user control. The configuration of
certain components can be further edited, even after they have been placed in the Layout and the
design has been compiled (see Placing Component Objects). Line Objects (wires) can have
identifying text added (see Line Property Sheet ).
Actual component settings can be customized through Control Dialog Boxes (see Component Object
Properties). Control Dialog Boxes for certain Combiners, Dynamics, Controls, Meters, & Telephone
Interface components can be minimized to create customized control surfaces (room combiners,
meters, level controls, mute buttons, preset buttons, telephone dialers, etc.). These control surfaces
can then be made user accessible, with other system components hidden on Layers which are
invisible to the user, and which are Password protected. (See Software User Interface.)
Individual or multiple Component Objects can be customized, connected, and then saved as new
Component Objects in the Processing Library. This can be done by selecting the desired object(s) in
the Layout, then pressing the Alt key and dragging the object(s) into an appropriate category in the
Processing Library. The Alt key can also be used to drag object(s) between design (.NEX) files, and to
copy objects within the same Layout. Right-clicking over objects (to Copy) and then right-clicking over
a Processing Library category (to Paste), can also be used.
Multiple component objects may be merged together using the Custom Blocks menu. Custom Blocks
can then be copied to the Processing Library as mentioned above. Custom Blocks can simplify the
design process by integrating frequently used component combinations, and can provide password
protection for intellectual property such as unique processing and component settings.
Right-clicking over the Processing Library will also allow new category files (.APL) to be created, for
quick access to specialized or often-used components. Existing category files (.APL) can be closed, to
customize the Processing Library. All available category files (.APL) can be viewed and opened from
the Processing Library Menu and from the Open dialog box. When Processing Library changes are
made, the affected category files (.APL) are automatically saved (under Shared Documents).
Object and Layout Text
The size and appearance of both text and objects can be customized. Special Text Objects can be
placed into the Layout using the Text cursor on the Object Toolbar. When selected, Component &
Text Objects display handles which can be dragged for re-sizing. Right-clicking over an object
provides a pop-up menu which includes the Edit Text option. Edit Text can also be accessed for a
selected object by simply pressing the Enter key. Text (and object) appearance can be customized
using the associated tools on the Format Toolbar. Also, Line Objects (wires) can have identifying text
added (see Line Property Sheet).
116
System Compiling Considerations
Once a system design is created (components placed & connected), the system can be compiled by
selecting Compile from either the File Menu or the Standard Toolbar. Compile analyzes the system
design and indicates design errors if there are any. If there are no errors, Compile proceeds and
allocates the required DSP resources.
Although Compile is an automatic process, certain settings can be pre-determined to help guide this
process. Control blocks (i.e., those processing blocks that do not have audio inputs or outputs) can be
Allocated To Unit, which assigns them to a particular Nexia device. This can be useful to dedicate
particular control functions to specific physical locations, for example, to have all RCB devices wired to
the same unit using a single cable.
Propagation Delay (also known as Latency) is an inherent time delay of the audio signals, which
increases with the amount of DSP processing and NexLink routing applied. Each NexLink 'hop' (oneway transmission) produces 0.67mS delay. Therefore, system outputs can have different amounts of
propagation delay. Compile determines worst-case propagation delay for a system, and applies Delay
Equalization to synchronize all audio outputs. In applications where audio output synchronization is
not important (audibly isolated areas), then Delay Equalization may be disabled on individual Input
Output components (DSP blocks) or system wide. See Object Property Sheet and Compile Options.
For visual aids in determining DSP block allocations, see Display Options. A system design file must
be compiled before it can be downloaded to NEXIA devices (see Send Configuration).
Compile results may be reviewed at any time (see Tools Menu > Layout Compile Results).

Compile Error Messages
Validation of the Topology Map
Message:
The Automatic Mixer (object code '__') at [__,__] has no active audio output.
Explanation:
An Auto Mixer Main Output is connected to a Mix-Minus Combiner
input, but appropriate audio output connections have not been made.
Mix-Minus Combiners allow Auto Mixers to share
control data only, and do not support audio input or output.
Message:
Explanation:
Unintended use of Combiner block detected.
A source, other than an Auto Mixer Main Output, is connected to a
Mix-Minus Combiner input. Mix-Minus Combiners allow Auto Mixers to share
control data only, and do not support audio input or output.
Message:
The main output of an Auto Mixer is connected to more than one
Combiner block.
Explanation:
The main output of an Auto Mixer can be connected to only a single
Combiner input (Mix-Minus or Room). Otherwise, Auto Mixer control
data might be shared with multiple groups of combined mixers, causing
convoluted behavior.
Message:

Messages:
Some DSP blocks do not have inputs. Ignore them ?
Some DSP blocks do not have outputs. Ignore them ?
Explanation:
These messages appear only if the flag 'Prompt To Stop Compilation
On Warnings' is set under Tools>Options>Compile. If the choice to
'Ignore' is selected, then the warning "Ignored '...' (object code '...') at
[__, __]" will be listed in the compile results. If the 'Prompt To Stop
Compilation On Warnings' flag is not set, then compilation proceeds
and 'Ignores' automatically.
118
Messages:

Explanation:
The first warning is issued for each DSP block in the layout that is considered
outdated. One of the subsequent messages will also appear, depending upon
whether there is only one outdated block or multiple outdated blocks detected.
Messages:
The algorithm for the '__' block (object code '__') at [__,__] has been eliminated.

Explanation:
These messages are similar to the ones above. The difference is that they are
not warnings, but errors.
Message:
Nothing to compile !
Explanation:
All objects placed in layout have been ignored.
Message:
Feedback loop detected.
Explanation:
The potential exists for an audio path to be indirectly looped back
upon itself. This condition could be dangerous, and is not allowed.
Allocation of DSP blocks to NEXIA Devices
Message:
The allocation of some DSP blocks cannot be resolved. You
should use NexLink I/O blocks to pass audio signals between units.
Explanation:
This system design attempts to pass audio signal(s) from one
Nexia unit to another. Use a pair of NexLink Input and Output
blocks to accomplish this.
Message:
Too many resources required in the unit #_.
Explanation:
The design requires more DSP resources than are available
Too many resources required in the units ##_.
from the Nexia device(s) specified in the Equipment Table.
Message:
Due to insufficient DSP resources all disjoint blocks have been ignored.
Explanation:
There are not enough DSP resources available in any Nexia unit in the
system. The compiler chose to ignore all blocks which are isolated from
any I/O blocks and, therefore, do not affect the rest of the system in any way.
119
Message:
Total maximal duration of delays exceeded in the unit #_.
Explanation:
The number of delay blocks, and their combined delay ranges,
exceeds the maximum capability of this unit. Currently, any single
NEXIA unit can provide a maximum of 15 seconds of delay blocks.
Matrix Mixers with Delay also contribute to this total, consuming
1 second per input channel.
Allocation of DSP blocks to DSPs
Message:
Allocating blocks to DSPs...failed to set up a feasible DSP task
schedule in the unit #__.
Explanation:
Although the total DSP power in the NEXIA unit is sufficient, compile
was not able to distribute the component objects among the
available DSPs. When the DSP load approaches 100%, it becomes
crucial that the objects be distributed more uniformly. Try moving
certain objects to another unit, or replace them with a comparable
set of smaller objects (within the same unit). Otherwise, it may be
necessary to add an additional NEXIA unit to the system, and move
large DSP blocks into it.
Assigning control blocks to NEXIA units
Message:
Some unconnected control blocks have been ignored.
Explanation:
Control blocks with no connections have been excluded from the
system. Only Logic Gate , Logic Delay, and Remote Preset Button
blocks can be ignored. When connected to the system, control dialogs
for ignored blocks cannot be accessed.
Message:
Feedback detected in the control network.
Explanation:
The potential exists for a control path to be indirectly looped back
upon itself. This condition could be dangerous, and is not allowed.
Message:
Unit #__ has too many control connections.
Explanation:
Although quite large, there is a limit to the quantity of control
connections within a single unit. Connections include both internal
(source and destination within same unit) and external links (source
or destination within this unit). Try moving certain control objects to
another unit (using fixed allocations),
120
Setting up the NEXIA units after a successful compilation
Messages:
Available range of Instance IDs is nearly exhausted.
Range of Instance IDs has been exhausted.
Explanation:
The total number of Instance IDs, as assigned to component and
line objects, is limited to 65,535. When component objects are
removed from a design, their Instance IDs are not automatically
re-assigned to new component objects. Therefore, the messages
above indicate that a significant number of Instance IDs has been
wasted. Set 'Reassign Instance IDs' under Tools>Options>Compile
and re-compile to recover wasted Instance IDs. CAUTION: This
will change most component Instance IDs, and will render existing
external control command scripts useless (unless Instance ID Tags
have been used in lieu of Instance ID numbers). Once Instance IDs
have been recovered, turn off 'Reassign Instance IDs' to avoid
further re-assignments.
121
System Network Considerations
Ethernet allows multiple NEXIA devices to be connected on a network, for system-wide programming
and control. Ethernet supports Software User Interface, Remote Control Bus, and Third-Party Control,
but does not include sharing of digital audio signals via NexLink.
The PC computer, running NEXIA software under Windows® XP Professional/Vista, must have a
10/100 BaseT network card (NIC) installed. When connecting directly to the Ethernet port on a single
NEXIA unit, a 'cross-over' CAT5 cable is used. When connecting to a network (or system) of multiple
NEXIA units, a 'straight-through' CAT5 cable is used (via an Ethernet switch). Ethernet switches (not
'hubs') must be 10/100 BaseT compatible, with sufficient ports for connection to each NEXIA unit
(multiple switches may be used). These connections also use 'straight-through' CAT5 cables. When a
system using only two NEXIA devices has been configured, and the computer connection is removed,
Ethernet may be connected directly between the two units using a 'cross-over' CAT5 cable.
Ethernet has a cable length limitation of 100 meters, between the Ethernet switch and a NEXIA device.
However, fiber-optic cable may be used to extend this distance limitation to 2 km. Fiber-optic cable
can be used with switches that have fiber-optic ports, or media converters can be used to interface
fiber-optic cable with standard RJ-45 ports. NOTE: Distances between devices in systems utilizing
NexLink are restricted to a maximum length of 5 meters for each NexLink cable. NexLink is proprietary
and is not Ethernet compatible. Therefore, Ethernet switches cannot be used within NexLink cabling.
The computer must be assigned an IP address (under Network Card Settings>Properties). Most
computers set TCP/IP address automatically, but NEXIA devices require manual assignment. Initially,
the computer IP addresses should be assigned as 192.168.1.X (where range of X = 1~254). Each
NEXIA device must also be assigned a unique IP address (see Device Maintenance). The factory
default IP address for all NEXIA devices is 192.168.1.101.
Many system designs require only a single NEXIA device. These systems do not exceed the number
of inputs/outputs, and the amount of DSP processing, provided by one specific model. When a single
unit is used, network considerations are simplified. No Ethernet switch is required. The only Ethernet
connection is that between the computer and the NEXIA device ('cross-over' CAT5 cable). A 'crossover' cable is included with each NEXIA device.
122
System Connect Considerations
The System Connect screen provides a System List (configured devices only) and a Device List (all
configured and non-configured devices). When a selection is made in the System List, Connect To
System will establish communication with, and retrieve the configuration from, the device(s) in that
system. Send System Config will attempt to send an open file of a properly compiled system
configuration to the device(s) specified in the Equipment Table. If the specified device(s) have an existing
system configuration, they may need to be Reset/Initialized before a new configuration can be sent
successfully. Reset/Initialize, as well as other device related settings, can be accessed by selecting
Device Maintenance.
Nexia software now employs the concept of "multi-client sessions". This is simply the capability for
multiple users to be connected to the same system simultaneously. Multi-client sessions also allow a
single user (PC) to be connected to multiple systems. In addition, a single user (PC) can even have
multiple connections to the same system. These multi-client sessions can include connections from both
Nexia software and daVinci control software.
Multi-client sessions include two 'privilege levels'. A High Privilege Session (designated HPS in the
Status Bar) is assigned to the first user connected to the system. HPS allows all system maintenance
normally associated with that specific user (see Passwords). Any additional connections to that system
will be Low Privilege Sessions (designated LPS in the Status Bar), which allow system control only,
regardless of user. When an HPS user disconnects, privilege levels do not update (connected users
remain LPS), and the next new user connection is assigned as HPS.
Send Configuration and specific Device Maintenance functions (Reset/Initialize, Set IP Address, and
Update Firmware) are not allowed during a multi-client session. All other system users must disconnect
before these functions can be performed. Send Configuration often affects multiple devices, which will be
unavailable to other users during this process. Device Maintenance functions affect individual devices,
which will be unavailable to other users during this process. NOTE: An exception to both situations
mentioned above is when all other users are connected via daVinci control software. Send Configuration
& Device Maintenance are allowed under these circumstances, and will automatically terminate any
daVinci sessions.

Proper Gain Structure
Proper gain structure is important because it affects signal-to-noise performance and available
headroom within a sound system. Every sound system has some inherent noise, whether it be selfgenerated by the internal electronics or induced into the signal path by external sources. Therefore,
unnecessarily low gain settings can result in signal levels which are significantly closer to the noise
floor, potentially causing a sound system to appear noisy. Conversely, excessive gain settings may
cause the audio signal to overdrive the electronics, resulting in severe distortion due to clipping of the
audio waveform. Besides being audibly undesirable, a distorted waveform can also cause damage to
some system components, such as loudspeakers.
In addition to its influence on signal-to-noise and available headroom, gain structure can affect other
aspects of sound system behavior. In particular, some audio components rely on signal strength as
part of their normal operation. These components may not perform as expected if they receive signals
that are lower, or higher, or even just different from what is anticipated. Examples of such components
are: Auto Mixers, Duckers, Levelers, Comp/Limiters, Ambient Noise Compensators (ANC), and
Acoustic Echo Cancellers (AEC).
Auto Mixer, Ducker, Leveler, and Comp/Limiter functions are triggered by input signals that exceed a
specified threshold. With Levelers and Comp/Limiters, signal levels below threshold are not
considered unusual (they simply are not affected by the component). However, Auto Mixers will not
pass signals that are below threshold, and Duckers will not automatically attenuate program signal if
the sensing input signal is below threshold. Furthermore, signals containing a large amount of
background noise can falsely trigger these components, if the level is set too high and/or the threshold
is set too low. It should also be noted that any real-time control of signal levels should not occur before
these types of components. For example, control of individual Auto Mixer channels should not take
place ahead of the Auto Mixer. Instead, the Auto Mixer Input Level controls (which are post-threshold)
may be used for this purpose.
Ambient Noise Compensation (ANC) relies on a continuous and accurate model of the program signal
level, to differentiate it from changes in the ambient noise level. So, real-time control of levels should
not occur after this type of component. Acoustic Echo Cancellation (AEC) relies on a continuous and
accurate model of the signal to be cancelled from the microphones. So, any real-time control of signal
levels at the loudspeaker output should be duplicated for the AEC Reference. If these signals are
different, a 2-channel ‘ganged’ Level control may be used.
126
What is proper gain structure? Generally speaking, proper gain structure is establishing and
maintaining good signal strength throughout the entire sound system. In most cases, this means that
the relative volume of loudspeakers should ultimately be determined by adjustment of the power
amplifiers (after prior system gain settings have been established). Other system outputs (such as
recording feeds) may require lower levels, which should be established by selecting an appropriate
reference level at the output itself. Other than real-time level control (as described previously), signal
attenuation within the system should be avoided.
To establish proper gain structure, the primary element is input gain. Each system input provides
adjustable Gain In (trim), with an associated Peak indicator. For best performance, increase gain on a
given input until the Peak indicator just begins to flash on normal signal content. The Peak indicator
first comes on with 6dB of headroom remaining (before clipping occurs). To provide additional
headroom (allowing for louder input signals), it is recommended that gain then be reduced by 12dB
(two 6dB decrements). To monitor system levels, Peak Meters should be connected at strategic points
in the signal path, including at the inputs. With gain settings as described above, input meters should
indicate peak levels between 6dB and 10dB on normal signal content (14dB ~ 18dB of headroom).
This will provide good signal-to-noise performance, with a safety margin of available headroom.
Throughout the rest of the system, various components will include level adjustment capabilities
(faders). By default, these faders are typically at 0dB (unity gain). This is a very good setting for most
applications, and does not necessarily need to be changed. However, any of these faders can be
used for real-time level control (as described above). Of course, faders can be used to ‘mix’ multiple
signals at differing levels (i.e. microphones at 0dB and music at -10dB). Faders can also be used to
compensate for gain reduction (Leveling, Comp/Limiting, etc.) which may have occurred earlier in the
signal path. Note: Floating Point DSPs allow this type of gain staging without the danger of clipping
distortion or the loss of data bits. As long as signal levels do not exceed maximum at the inputs or
outputs (A/D & D/A converters), extremely high and low level signals can be tolerated without negative
impact on quality. However, remember that some system components do not function well without
proper signal strength (as described previously).

System Control
Software User Interface
Once a system design is compiled and downloaded into NEXIA devices, the system can be controlled
in real-time the via the NEXIA software. The extent of control can be limited with different password
levels.
In addition, Control Dialog Boxes for certain Combiners, Dynamics, Controls, & Meters components
can be minimized to create customized control surfaces (room combiners, meters, level controls, mute
buttons, & preset buttons). These control surfaces can then be made accessible to the User, only with
a specific Password.
These control surfaces remain functional, even if other component settings are made inaccessible to
the User (via Password Level). The control surfaces can also remain visible, even if the components
they represent are made invisible (via Layer View). Therefore, a custom User control surface can be
created in the Layout, with User access allowed, but with all other system settings inaccessible (and
hidden). The size & shape of the Layout may be changed, and Toolbars hidden, to customize the
appearance of the User control screen.
Example of user control surface

Remote Control Bus
Remote Control Bus provides the connection for Volume 8, Select 8, Volume/Select 8, Voltage Control
Box, and Logic Box external control devices.
Each NEXIA device can support any combination of the controls mentioned above. Up to 12 controls
may be connected to each NEXIA device, on a daisy-chain 'network', with a maximum cable length of
1000 feet (300 meters). A Remote Control Bus Hub allows multiple branches on a control network.
Cabling and power for an RCB network can be calculated using a program (NexiaRCBCabling.hta)
found under Program Files/Nexia/Ultilities. Controls are wired in parallel (pin-for-pin), using 5conductor data grade cable (95~120 ohms nominal impedance; 16 pF/ft. max. capacitance; 65% min.
velocity of prop.).
Recommended cable: Gepco 18/22AXL, Liberty AXLINK, Liberty CRESNET, or equivalent
(use data pair for Hi & Lo; use power pair for + & -).
The 'network' requires termination at each 'end' for proper operation. All controls (and NEXIA) include
either a termination switch or jumper strap. These terminations should be disabled (switch out or
jumper removed) on all devices except those at the two extreme ends of the network. (See wiring
diagram below).
A control network may be wired with the NEXIA device at one end, and a control device at the other
end, creating one continuous run. In this case, the NEXIA device would have the 'term' switch
engaged (in), and the control device at the other end of the network would have the 'term' switch
engaged (in) or jumper installed. All other controls, between the NEXIA device and the last control,
would have their 'term' switches released (out) or jumpers removed.
If a control network needs to service two areas which are in opposite directions from the NEXIA device,
a network with two separate runs can be created. This type of network actually remains as a single
run, but is configured with the NEXIA device in the middle. Therefore, only the controls at the two
extreme ends of the network would have their 'term' switches engaged (in) or jumpers installed. All
other controls (including the NEXIA device), between the two end controls, would have their 'term'
switches released (out) or jumpers removed. (See network diagrams below.)
129
130
Remote Control Bus Hub
The Remote Control Bus Hub provides eight parallel ports for the connection of remote control devices
to an Nexia® system. Each port can accept multiple remote controls connected in a 5-wire daisychain. A single Hub, connected to a single Nexia unit, allows multiple branches to be added to the
remote control network. Also, maximum cable length is calculated only across the two longest network
branches, thereby effectively extending the network range. The Remote Control Bus Hub can be used
with any combination of control devices, including Volume 8, Select 8, Volume/Select 8, Logic Box,
and Voltage Control Box.
Example Control Network
Third-Party Control
After initial programming & configuration, NEXIA systems may be controlled by RS-232 communication
from third-party control systems such as AMX® or Crestron®, using the Serial Control Port. See RS232 and Telnet Protocol.
131
RS-232 and Telnet Protocol
Overview
Nexia can be controlled via the control dialogs in the Nexia software, or via third-party controllers using
RS-232 or Telnet.
For control of Nexia, Biamp created NTP (Nexia Text Protocol). This simply means that Nexia will accept
strings of ASCII characters to control and read settings of gain, mute, logic state, frequency, audio levels,
and other parameters of DSP Blocks in Nexia products.
NTP strings can be sent via third-party controllers using RS-232 (see RS-232 Control) or Telnet via
TCP/IP (see Telnet Control). A line feed needs to be sent after each command string sent.
The NTP string is structured in the following order:
Command DeviceNumber Attribute InstanceID Index1 Index2 Value <LF>
NTP strings require a space between each parameter; the last character in the string needs to be a line
feed <LF>. A space is not required before a line feed, but is acceptable and is used in examples shown
in this manual (for legibility only). A space normally proceeds the carriage return/line feed <CR><LF> in a
response to a GET command (see Command and Responses).
For each control string a few components will need to be derived from the Nexia software: Device
Number, InstanceID, and Index. Command and Attribute are derived from this document. In a SET
command, Value is used to specify what the DSP block attribute is to be set to. In an increment or
decrement (INC or DEC) command Value is used to specify how much the DSP block attribute is to be
changed by.
**Note** Nexia software will assign an Instance ID number to each DSP block on the initial Compile of
the system. Subsequent compiles will not change the Instance ID numbers unless the "Reassign
Instance IDs" check box is selected in the ‘Compile’ tab of the ‘Options’ screen (located on the Tools pulldown menu) in the Nexia software. Custom names (Instance ID Tags) may be assigned to DSP blocks,
and used in lieu of Instance ID numbers within NTP command strings.
Example: A string to control a Fader Level might look like this: SET 1 FDRLVL 2 1 9 <LF>.
The individual components for this string are:
Notice that Index2 is not used since there is nothing entered in this parameter.
Example: A string to Mute a Standard Mixer Output: SET 3 SMMUTEOUT 5 5 1 <LF>
The individual components for this string are:
Notice that Index1 is not used since there is nothing entered in this parameter.
Example: A string to turn up (increment) a Crosspoint on a Matrix Mixer: INC 2 MMLVLXP 4 3 2 1 <LF>
The individual components for this string are:
In this example Index1 and Index2 are both used, together they specify which Crosspoint to change.
132
RS-232 Control
The RS-232 port on the back of an Nexia unit is set to a default baud rate of 38400, 8 data bits, no parity,
1 stop bit, and no flow control. (38400:8:None:1). If multiple Nexias are connected together in a system
then only one RS-232 port needs to be connected to a third-party control system; communication data is
shared via Ethernet through a switch.
When controlling multiple Nexia units that are not part of the same NEX file, each Nexia unit will need to
be addressed via its own RS-232 port from a control system or PC. Nexia units cannot be linked together
via RS-232, like some other BIAMP products can.
(The RS-232 baud rate can be set to 9600, 19200, 38400, 57600, or 115200 – default is 38400)
A straight through PC Serial Cable is used to communicate from an RS-232 port on a third-party controller
(or PC*) to the RS-232 port located on the back of an Nexia unit.
(* A PC can send/receive NTP Strings, using a terminal emulator program such as HyperTerminal.)
Telnet Control
Nexia can be controlled using Telnet via TCP/IP. The same command strings that are used for RS-232
Control are used for Telnet.
When controlling multiple Nexias that are not a part of the same NEX file, each Nexia device will need to
be addressed via its own Telnet session from a control system or PC.
Nexia supports standard Telnet Echo Negotiation. By default, the Telnet server will echo characters sent
to it, one by one.
To turn echo OFF during a session:
Send byte sequence 0xFF 0xFE 0x01.
Receive 3 byte response from server (0xFF 0xFC 0x01 = echo OFF).
Send desired commands.
To turn echo back ON during a session:
Send byte sequence 0xFF 0xFD 0x01.
Receive 3 byte response from server (0xFF 0xFB 0x01 = echo ON).
Send desired commands.
133
Command
SET – Tells Nexia that a DSP attribute is to be set to a specific value – may contain negative numbers
and/or decimal points
GET - Tells Nexia that a DSP attribute is to be read – the response may contain a decimal point and/or a
negative number (see Responses).
INC - Tells Nexia that a DSP attribute is to be incremented by a specific amount
DEC- Tells Nexia that a DSP attribute is to be decremented by a specific amount
RECALL – Tells Nexia that a preset is to be recalled.
DIAL – Tells the Nexia that a dial command is being sent
SETL and GETL can be used if negative numbers and/or decimals are not supported by a control system.
SETL – Tells Nexia that a DSP attribute is to be set to a specific value, no decimal places or negative
numbers –To convert a dB number: add 100 to the desired level and then multiply by 10.
Example: To set a level to –60.5dB, add 100 (-60.5 +100 = 39.5). Then multiply by 10 (39.5 X 10
= 395). Instead of Value being –60.5, Value after this SETL command will equal 395.
GETL - Tells Nexia that a DSP attribute is to be read without negative numbers or decimals. To convert
this number to dB: divide the number by 10, then subtract 100.
Example: With a returned GETL response of 405, divide by 10 (405 / 10 = 40.5), and then
subtract 100 (40.5 – 100 = -59.5dB)
For your reference, the SETL/GETL Table on the following page shows .5dB increments converted into
the SETL/GETL format.
Some Attributes do not support all commands. The Attribute section defines which commands support
SET/SETL, GET/GETL, INC, or DEC functions. RECALL is only used on preset commands. DIAL is only
used on telephone dialing commands.
*When GET or GETL is used, a Value will not need to be specified since GET/GETL is a request
command. A Value must be specified in order for strings with SET/SETL, INC, DEC, and RECALL to
work.
Note: SETD, GETD, INCD, DECD, SETLD, and GETLD commands may be used when a ‘full path’ serial
response to the command is desired (see Responses). A ‘full path’ serial response will provide
identification of the target object, the original command, and the resulting value or state.
134
135
Device Number
A Nexia Device Number represents the physical Nexia box’s defined address. The Nexia software
automatically sets this number when a system is Compiled and loaded.
The Device number that a DSP block has been assigned to can be determined in 3 ways:
First Way:
1) Right click on the DSP block and select ‘Properties’.
2) Click on DSP 1 attributes tab and scroll down. The device that the block is assigned to will be
displayed in the ‘Allocated To Unit’ field.
Second Way:
1) In the Display tab of the Options screen select "Display Device Assignment in DSP
Block info field". This will display the device that each DSP block is assigned to on the main screen.
Third Way:
1) While connected an Nexia’s RS-232 port, type the string; GET 0 DEVID
Nexia will return the Device Number of the unit you are connected to.
136
Attribute
The Attribute defines the portion of the DSP block to be controlled (fader level, crosspoint mute etc).
The following tables show whether each NTP Attribute supports SET/SETL, GET/GETL, INC, and DEC
Commands, as well as the Value range that the Attribute will accept. Index1/Index2 determines
whether Index1, Index2 or BOTH are needed for a NTP String to be complete.

room is either separate (group 0) or combined with other rooms of the selected group (1~16). All other
rooms maintain their previous group assignments. Index1 represents the room being addressed. As
rooms are combined, room levels become ganged, so only one output level needs to be addressed.
Note: For Wall State, Index1 indicates the wall to be affected and Value indicates the actual wall state
(down=open=combined; up=closed=separated).
Example: Set Device 1 Room Combiner Wall State at Instance 4 Wall 2 to up (close/separate).
Result: SET 1 RMCMBWALL 4 2 1 <LF>

Note: For attributes with 2 Index fields, Index1 is the input/row, and Index2 is the output/column.
Example: Set Device 1 Router Crosspoint at Instance 98 Row 4 Column 5 to muted.
Result: SET 1 RTRMUTEXP 98 4 5 0 <LF>
Delay Blocks
* Can contain a decimal number.
Note: Value Range is from 0 to the maximum value for the specific delay block. For example, a 50mSec
delay has a maximum setting of 1717 centimeters, 17 meters, 676 inches, or 56 feet.
Example: Set Device 1 Delay In Centimeters at Instance 24 to 40 centimeters.
Result: SET 1 DLYCM 24 40 <LF>
148
Control Blocks
* Can contain a decimal number.
Note: Instead of SET, SETL, GET, GETL, INC, or DEC; the Preset attribute uses RECALL as the
command. Preset numbers begin at 1001. Regardless of preset name, the first preset defined is 1001,
the second is 1002, and so forth. However, the numbers of any deleted Presets will not be available.
Since Presets apply to entire systems, the Device Number will always be 0 for Preset strings.
Example: Recall Device 0 Preset number 1001.
Result: RECALL 0 PRESET 1001 <LF> (use RECALL instead of SET/GET commands)
149
Meter Blocks
* Can contain a decimal number.
Note: Meters only use GET and GETL commands, which do not include a Value. Instead, Nexia will
respond to these GET/GETL commands with the requested value (current level).
Example: Get Device 1 RMS Meter Level at Instance 48 Meter 1.
Result: GET 1 RMSMTRLVL 48 1 <LF> (use GET/GETL commands only)
Generator Blocks

150
Instance ID
Nexia uses an Instance ID number to specify the exact DSP block to be controlled. Custom names
(Instance ID Tags) may be assigned to DSP blocks, and used in lieu of Instance ID numbers within NTP
command strings. Instance ID Tags may be up to 32 characters, but may not start with a number. If the
Instance ID Tag includes spaces, it must be double-quote delimited ("Instance ID Tag") when used in a
command string. The Instance ID number (and Instance ID Tag) can be found by right-clicking the DSP
block and selecting "Properties". Both identifiers are available on the DSP Attributes 1 tab.
The property sheet can only be accessed in an off-line screen.
**Note** Nexia software assigns an Instance ID number to each DSP block on the initial system Compile.
Subsequent compiles will not change the Instance ID numbers unless the "Reassign Instance IDs" check
box is selected in the ‘Compile’ tab of the ‘Options’ screen (located on the Tools menu) in Nexia software.
If one or more DSP block is disconnected from the audio path (when connections are not made to at least
one input or output) Instance ID numbers will be unassigned. Instance ID numbers will be reassigned
once the DSP blocks are properly connected again. The use of Instance ID Tags (in lieu of Instance ID
numbers) may help prevent command string conflicts caused by reassignment of Instance ID numbers.
151
Index
Index refers to inputs, outputs, or cross points of an Attribute. Some Attributes will need an Index1 (Input
or Row) and/or an Index2 (Output or Column). The tables in the Attribute section will define which, if any,
indexes are required for the string.
Example: INC 1 AMLVLIN 4 1 1 <LF>
In an Auto Mixer on Device 1 we are increasing the level of input 1 on instance ID 4 by 1dB. Index1 is
used to represent the input number.
Example: DEC 2 AMLVLOUT 6 1 2 <LF>
In an Auto Mixer on Device 2 we are decreasing the level of output 1 on instance ID 6 by 2dB. Index2 is
used to represent the output number.
Example: SET 1 MMLXP 5 1 2 –5 <LF>
In a Matrix Mixer on Device 1 we are setting crosspoint 1:2 (Input/Row 1, Output/Column 2) level to –5dB
on instance ID 5.
Note: For commands with 2 Index fields, Index1 is the Input/Row, and Index2 is the Output/Column.
152
Value
Value determines what a DSP block is being set to, incremented by, or decremented by. The Attribute
section will define which type of value the string will need in order to execute the NTP string.
Example: INC 1 AMLVLIN 4 1 1 <LF>
In an Automatic mixer input level string, the Value equal to 1 states that the fader is to be incremented by
1 dB.
Example: SET 2 MMLVLIN 5 2 –100 <LF>
In a matrix mixer input level string, the value is set to –100dB.
Example: RECALL 1 PRESET 1004 <LF>
For a preset recall we are telling device 1 to recall the fourth preset.
*When GET is used, a Value will not need to be specified since GET is a request command. A Value
must be set in order for SET, INC, DEC, and RECALL command strings to work.
Example: GET 4 MMLVLOUT 5 <LF>
We are asking the level of a matrix mixer’s output. There is no Value required for this string.
153
Responses
When a successful SET, SETL, INC, DEC, or RECALL command is sent to an Nexia device via RS-232
or Telnet, Nexia will respond with: ‘+OK’ followed by a carriage return and line feed.
Example: Sending the string: SET 2 AMLVLIN 4 2 1 < LF> will result in an: +OK<CR><LF> response.
A successful GET or GETL command will result in a numerical response to the command string followed
by <CR><LF>.
The response from an NTP string with a GET command may contain a decimal point (with 4 numbers
after the decimal) and/or negative numbers, depending on type of Attribute addressed. If the control
system does not support negative numbers or decimal places a GETL command may be used instead
(see page 6).
Example: After sending the above example to an Nexia device the string:
GET 2 AMLVLIN 4 2<LF> would result in the response: 1.0000 <CR><LF> this tells us that the level is
currently set to 1dB.
If an incorrect command string is sent, an Nexia will respond with: -ERR<CR><LF>
A space normally proceeds the carriage return/line feed <CR><LF> in a response to a GET command,
but this space is not present in the standard ‘+OK’ or ‘-ERR’ responses.
Note: SETD, GETD, INCD, DECD, SETLD, and GETLD commands may be used when a ‘full path’ serial
response to the command is desired. A ‘full path’ serial response will provide identification of the target
object, the original command, and the resulting Value. A ‘full path’ response to a valid command will
always begin with a pound sign (#) and end normally (as described above).
Examples:
Command = SETD 1 IPADDR 192.168.1.197
Response = #SETD 1 IPADDR 192.168.1.197 +OK
Command = GETD 1 IPADDR
Response = #GETD 1 IPADDR 192.168.1.197
Command = SETD 1 MMLVLXP 38 1 1 -1.1
Response = #SETD 1 MMLVLXP 38 1 1 -1.1 +OK
Command = INCD 1 MMLVLXP 38 1 1 1.0
Response = #INCD 1 MMLVLXP 38 1 1 -0.1000 +OK
It should be noted that, unlike SETD commands/responses, INCD or DECD commands and responses
will most often contain different Values. This is because SETD commands specify an exact Value (which
will be the same in the response), whereas, INCD and DECD commands specify a ‘change’ in Value.
154
Control Dialog - Overview
Nexia software can be used to control Nexia units real time via a network. After connecting to a Nexia
device, users, technicians, and designers (as determined by passwords) can access their appropriate
level of control of the system. Depending on the authorized access level of control Levels, Meters,
Presets, and layers can be accessed and changed.
Level Control, Invert, Meter, and Preset block control dialog screens can be minimized and arranged to
provide a simple, and intuitive, user interface for the system. Connecting Nexia’s Ethernet port, through a
switch, to network jacks in various locations can provide control to the system from different locations via
a Laptop or Desktop computer.
Note: Nexia’s control network can be easily shared on an existing network without compromising
network bandwidth. This includes Ethernet connections, but not NexLink which remains separate.
155
Control Dialog - Levels, Presets, & Meters
Levels
Once Level Controls are placed in a signal path audio levels can be increased, decreased or muted as
needed.
Presets
Once Presets are created, Preset buttons can be placed on screen and used to easily recall different
scenarios.
Meters
If meters are placed on screen, users can view real time Signal Present, RMS, Peak, and Logic
indications.
156
HyperTerminal
HyperTerminal is a useful tool that comes with Windows® and can be used for RS-232 purposes. Simply
open a HyperTerminal session by going to: Start> Programs> Accessories> Communications>
HyperTerminal. Enter a name for your connection and click ‘OK’. Under the pull-down menu labeled
‘Connect Using’ select the location of your RS-232 Comm. port.
Under the Comm. port properties set it to 38400, 8, None, 1, and None as shown below. Now
HyperTerminal is ready to use. Nexia does not echo characters typed, so if you want to view what is
being typed into Nexia, click on "echo typed characters locally" in the ASCII setup screen.
Windows® is a registered trademark of Microsoft Corporation.
157
IP Address Commands
Nexia has some useful IP and reset tools that may be useful when returning to older systems for service
work.
Nexia will automatically output its IP Address through the RS-232 port when it is powered up and
functioning. Simply have a straight through RS-232 cable connected to Nexia and a PC with
HyperTerminal running. When Nexia is powered up it will print the data in the HyperTerminal screen.
Get Device ID
By typing ‘GET 0 DEVID <LF>’ in HyperTerminal, Nexia will reveal the device number that is assigned
to that particular device within the system. If an Nexia does not have a system loaded into it, the device
ID will always be 0. Device ID 0 is always used for network related ATP commands and reset related
commands.
Get/Set IP Address
By typing ‘GET 0 IPADDR <LF>’ in HyperTerminal Nexia will reveal the IP Address it is set to.
Substituting the ‘0’ for a 1, 2, 3, etc will tell Nexia to reveal the IP Address for the device who’s number is
1, 2, 3 etc. A ‘0’ asks for the IP Address of the Nexia you are currently connected to. Note: You can only
use a 1, 2, 3 etc if there is a system loaded into the Nexia’s. If it is a single device system, the only device
number will be 1.
If an Nexia does not have a system loaded into it, you can set the IP Address via the RS-232 port.
Example: SET 0 IPADDR 192.168.1.101 <LF>. If there is no DAP file in the Nexia, and the command is
typed correctly, Nexia will send back a ‘+OK’ response. You will need to power cycle the Nexia for the
new IP Address to take effect. As stated above, Nexia will output the IP Address when powered up, or
you can use the GET IPADDR command mentioned above.
Get/Set Subnet Mask
By typing ‘GET 0 SUBNETMASK <LF>’ in HyperTerminal, Nexia will reveal the Subnet Mask it is set to
use. Substituting the ‘0’ for a 1, 2, 3, etc will tell Nexia to reveal the IP Address for the device who’s
number is 1, 2, 3 etc. A ‘0’ asks for the IP Address of the Nexia you are currently connected to. Note: You
can only use a 1, 2, 3 etc if there is a system loaded into the Nexia’s. If it is a single device system, the
only device number will be 1. By default, the subnet mask is set to 255.255.255.0
If an Nexia does not have a system loaded into it, you can set the Subnet Mask via the RS-232 port.
Example: SET 0 SUBNETMASK 255.255.255.0 <LF>. If there is no DAP file in the Nexia, and the
command is typed correctly, Nexia will send back a ‘+OK’ response. You will need to power cycle the
Nexia for the new subnet mask to take effect. As stated above, Nexia will output the default gateway IP
Address when powered up, or you can use the GET SUBNETMASK command mentioned above.
Get/Set Default Gateway Address
By typing ‘GET 0 DEFAULTGW <LF>’ in HyperTerminal Nexia will reveal the Default Gateway IP
Address it is set to use. Substituting the ‘0’ for a 1, 2, 3, etc will tell Nexia to reveal the IP Address for the
device who’s number is 1, 2, 3 etc. A ‘0’ asks for the IP Address of the Nexia you are currently connected
to. Note: You can only use a 1, 2, 3 etc if there is a system loaded into the Nexia’s. If it is a single device
system, the only device number will be 1.
If an Nexia does not have a system loaded into it, you can set the Default Gateway IP Address via the
RS-232 port. Example: SET 0 DEFAULTGW 192.168.1.1 <LF>. If there is no DAP file in the Nexia, and
the command is typed correctly, Nexia will send back a ‘+OK’ response. You will need to power cycle the
Nexia for the new default gateway IP Address to take effect. As stated above, Nexia will output the default
gateway IP Address when powered up, or you can use the GET DEFAULTGW command mentioned
above.
158
Get MAC Address
By typing ‘GET 0 MACADDRESS <LF>’ in HyperTerminal Nexia will reveal the MAC Address of the
Nexia’s network interface. Substituting the ‘0’ for a 1, 2, 3, etc will tell Nexia to reveal the MAC Address
for the device who’s number is 1, 2, 3 etc. A ‘0’ asks for the MAC Address of the Nexia you are currently
connected to. Note: You can only use a 1, 2, 3 etc if there is a system loaded into the Nexia’s. If it is a
single device system, the only device number will be 1.
Reset
In rare instances it may become necessary to reset the Nexia device. A reset can be accomplished
through the device maintenance screen, and this is the desired method for a reset. However, there is a
reset command available via the RS-232 port. Simply type: CLEAR 0 DEVCONFIG <LF> and the device
will be reset.

Batteries
Note: Batteries for all Spectron LSN inverter systems are
shipped separately.
Batteries must be installed and energized within 90 days of
shipment or warranty is void.
Spectron LSN’s batteries provide sufficient power to maintain the output voltage of the inverter for a minimum of 90 minutes. All batteries are enclosed in lockable cabinets. Adequate space is provided to ensure easy routine maintenance.
Standard Batteries
Sealed Lead-Calcium — Type S
Spectron LSN’s standard lead-calcium battery is completely sealed and requires no addition of water over its life expectancy. It is constructed with a polypropylene case and cover, which include UL-recognized, low-pressure safety release vents. No gassing will occur in normal use. The elements utilize calcium grid alloy, and the electrolyte is trapped in absorbent glass mat (AGM) separators. Designed life expectancy is 10 years at 77°F/25°C.
Long Life
Sealed Lead-Calcium — Type G
This optional battery is completely sealed and requires no addition of water over its life expectancy. Quick inspection and installation are possible
because the electrical connections are located at the front of the battery. The
battery case and lid are constructed of flame retardant ABS material. The
plates are separated by a highly porous fiberglass mat, which functions as the
electrolyte retainer and provides the highest possible oxygen recombination
efficiency. Type G batteries have a life expectancy of 20 years at 80°F/27°C.
Longest Life, Wet-Cell
Nickel-Cadmium — Type N
This optional battery is maintainable and requires the addition of distilled water over its life expectancy. The nickel-cadmium battery provides operation over the widest range of temperatures, from 0°C/32°F to 60°C/140°F. Translucent polypropylene containers are standard. Each cell is provided with a flip-top, flame-arresting, UL-recognized vent cap. Interior cell construction consists of pocket plate nickel-cadmium elements in an alkaline electrolyte. Covers are supplied to provide dead-top isolation. Type N batteries have a 25-year life expectancy at 77°F/25°C.
3 of 5 Required Submittal Pages

Advanced Design
The basic elements of an inverter system are batteries,
an inverter, a charger and a transformer. Spectron LSN,
however, is unlike traditional IPS, FT or UPS systems
because of its innovative design.
This pulse width modulated (PWM) high-frequency inverter
utilizes the latest IGBT (Insulated Gate Bipolar Transistor)
technology. The AC-in to AC-out operating efficiency is 98%,
well above other central inverter system equipment. This
outstanding efficiency translates to lower operating costs.
Plus...
Compatibility
Spectron LSN systems provide 100% compatibility with
all connected loads. “No break” sinusoidal output assures
that even voltage-sensitive or frequency-sensitive loads will
operate normally during emergency operation.

Spectron LSN - A Major Advance In Life Safety
PWM Technology
Pulse width modulated (PWM) inverter control is designed
to produce the output wave form by switching battery
current at a high-frequency rate. The
primary circuit of the inverter is
made up of four Insulated Gate
Bipolar Transistors (IGBT). IGBTs provide the multiple
benefits of compactness, high
efficiency, low maintenance
and long equipment life, as
well as maximum adaptability
and control. The four IGBTs are
sequenced on and off at a 16,000
Hz rate. Because of the inverter’s
high-frequency switching response time,
many compatibility problems with loads such as power
factor-corrected ballasts, HID lighting and microprocessorcontrolled equipment are eliminated. PWM design results in:
Interruption-Free Power
Spectron LSN provides continuous power to
all critical life safety loads and other secondary
support systems. This “no break” switching
between utility and inverter power means that
all connected equipment will continue to operate
normally under emergency conditions. Voltage Regulation
Spectron LSN’s Boost Tap Regulation protects
your loads from “brownouts” and recurrent low-voltage transients by sensing any drop in
voltage and “boosting” the voltage back up to
nominal without drawing from the batteries and shortening their lives.
Mixed Loads
Spectron LSN’s “no break” design provides
continuous operation to mixed loads. Capacitive,
inductive or resistive loads will operate normally,
as will voltage-sensitive or frequency-sensitive
equipment.
