DESIGNING AND INSTALLING A C-6 SYSTEM
System Design
It is always good to get as much information from the client/user/homeowner as possible when
designing a multi-source, multi-zone system. What sources are they going to use? How many
zones will be included in the system? Some zones may only require speakers for background
music, while other zones may include a TV or video display for movies, sports and news. It’s all
part of the same system and planning ahead will insure that the system does what the user
requires…or asks for later.
Head End Considerations
When planning a whole-house system, whether new or existing construction, always try to find
the most convenient location for the system components. Try to find a central location to pull the
wire runs with adequate space for the components and room to work on them. Certainly not the
least important consideration should be convenience for the user. Remember: once the system is
installed, the user is still going to need to load discs or tapes or program material…easy access is
essential. For service or upgrading components, an equipment closet with rear access to the
components is ideal but not always possible. Consider a pull-out rack mount system if rear
access is not possible. Leave plenty of extra wire to be able to easily remove components if they
should need service or replacing.
Zone Considerations
Think the system through in terms of how the system will be used. What is the layout of each
room? Where will the speakers go? Where will the keypads go? Are there going to be any other
system components in the remote zones such as TV’s? Be sure to pull all required cabling and
observe all local building and electrical codes.
INSTALLATION
Controller Location
The C-6 should be located at the main termination of all wire and cable runs. The source
components (CD, DVD, Satellite Receiver, VCR, etc) should also be installed at this location.
The C-6 and source components can be placed on shelves in a wall unit in a media room, or rack
mounted in a standard 19” rack mount system. Always provide convenient access for loading
CDs and DVDs. Easy access for service should also be a consideration.
Ventilation
The C-6 must be placed in a location that allows adequate airflow. Leave at least two inches
above and below the unit to allow air to flow freely through the vent holes on the top, bottom and
sides. Blocking the vent holes can inhibit airflow and possibly damage the unit. Removing the feet
will inhibit airflow and is not recommended. Additionally, care should be taken in to leave plenty of
extra room for wires and cables. Extra wire cramped in around the unit can block side vents and
inhibit proper airflow.
Rack Mounting
Figure 9. VP-1 Vent Panel
10
When rack mounting the C-6 Controller and other system components, it is recommended that
one Nexus VP-1 Vent Panel be used above and below the C-6 Controller to provide adequate
airflow for cooling. If X-1 and X-2 Expansion Controllers are being used, a VP-1 between each
component is recommended.
Keypad Location & Mounting
The K-8 and K-22 Keypads should never be mounted in the same J-box with AC house wiring or
any other high voltage device such as a light switch. Avoid mounting the keypads in areas with
high moisture such as around sinks, bathtubs, showers or outdoor locations that will be exposed
to rain or high humidity. Care should also be taken to avoid mounting the keypads in locations
that will be exposed to direct sunlight. Sunlight can interfere with the IR sensors on the keypads
and interfere with system performance.
WIRING
One of the most important aspects of system design and installation is the wiring infrastructure.
The Nexus C-6 Phantom Control Circuitry provides installation options far beyond typical multiroom system controller capabilities. Simply put, the Phantom Control feature allows utilizing
existing speaker wires for both the speaker level audio signals and control signals by combining
speaker level audio, control signals and power for the keypads on the same four-conductor wire
that is typically used for just speaker level audio. What this means is that the C-6 Controller with
K-8 or K-22 Keypads can be used to upgrade an existing single-zone audio system with volume
controls to a multi-source, multi-zone Keypad controlled A/V distribution system.
Phantom Control increases the flexibility of the C-6 System to just about any application, but extra
care should be taken in tracing and labeling wires in both new and existing construction
installations. Pay careful attention to the wiring diagrams in this manual and to the markings on
the components to avoid wiring errors that can potentially damage the system components.
WARNING: THESE ARE NOT TYPICAL SPEAKER TERMINALS. IMPROPER CONNECTION
OF SPEAKERS OR KEYPADS CAN CAUSE DAMAGE TO THE CONTROLLER, THE KEYPADS
AND SPEAKERS. CHECK ALL CONNECTIONS BEFORE TURNING ON THE MAIN POWER.
NEXUS WARRANTY DOES NOT COVER DAMAGE CAUSED BY IMPROPER CONNECTIONS.
When planning the wiring infrastructure, always pull extra wire. In new construction, wires can be
damaged during construction, so it is a good idea to use wire with additional conductors in case a
nail or staple gets run through a wire. Additionally, even though the system has been designed
and contracted based on extensive interviews with the homeowner, things change. The
homeowner may decide to add music, video and control to additional rooms long after the walls
have been sealed up. In new construction, always pull wire to every room that could ever possibly
be added to the system, so when the homeowner decides to add a room, the wire is already in
place. Pull speaker/control wire for audio and control as well as coax for video distribution. Pull
each wire or cable to an appropriate location for keypads, speakers and video displays.
Terminate with appropriate wall plates or keep a map detailing exactly where the wire runs are
terminated in the walls. Always label the wire runs by room and device to assist in installation and
troubleshooting.
11
Figure 10. Typical Zone Configuration
Zone Wiring
Keypads/Speakers - Pull four conductor wire in home-runs directly from each keypad location to
the C-6 Controller location. Pull two conductor wire of the same gauge from the keypad location
to each of the speakers in a zone. 16AWG stranded up to 75’; 14AWG stranded up to 100’. Nonshielded preferred.
NOTE: Min load: 8 ohms per zone. Do not load more than one pair of 8 ohm speakers per zone.
This can cause the unit to go into protection and may possibly blow fuses.
Video – Pull in home runs directly from each possible TV or video display location directly to the
C-6 Controller location. RG6 quad shield preferred. Up to 150’. Terminate with quality gold plated
RCA type male plugs.
Paging
Audio – Use a quality audio cable from the telephone system line audio or paging output to the
Page Audio IN on the C-6 Controller. Line level audio can typically be run up to about 50’.
Anything beyond that should be run through an appropriate balanced line adaptor. Terminate with
a quality gold plated RCA type male plug at the head end and terminate as appropriate for the
paging device used.
Video – Pull RG6 quad shield from device (front door camera, etc.) to be displayed in Page mode
to the C-6 Controller location. If device is local to the controller, an appropriate video patch cable
is acceptable. RG6 quad shield up to about 150’. Terminate with a quality gold plated RCA type
male plug at head end and with connector appropriate to the Page video device to be displayed.
Mute – Pull two conductor stranded wire from the 12VDC output on the device that will trigger
zone muting to the C-6 Controller location. Terminate with a 2.1mm coaxial plug at head end. Pin
= +12VDC, sleeve = ground. 20AWG up to 500’; 18AWG up to 1000’. Non-shielded preferred.
NOTE: Zone mute function must be configured in the C-6 System Setup. See section:
PROGRAMMING – Page/Mute.
Page - Pull two conductor stranded wire from the 12VDC output on the device that will trigger
paging to the C-6 Controller location. Terminate with a 2.1mm coaxial plug at head end. Pin =
+12VDC, sleeve = ground. 20AWG up to 500’; 18AWG up to 1000’. Non-shielded preferred.
NOTE: Paging function must be configured in the C-6 System Setup. See section:
PROGRAMMING – Page/Mute
12
RS-232 – RS-232 though capable of communicating complex control strings has limitations in its
overall transmission length. Typically RS-232 runs should be limited to about 50’. The cable is a
nine conductor cable terminated with a DB9 connector. A finished cable of appropriate length is
recommended for this application. DB9 Serial cable. Pin out: Pin 2=Tx, Pin3=Rx, Pin 5=GND.
Feature Buss – This port is currently inactive. It will provide future control expansion and
capability. Periodically visit www.nexusaudiosystems.com for updates.
Trigger – Pull two conductor stranded wire to a voltage sensing device to be controlled by the C6. Terminate with the included two terminal plug-in screw connector at the head end. Terminate
as appropriate for device to be controlled. 20AWG up to 500’; 18AWG up to 1000’. Non-shielded
preferred.
CONNECTING THE CONTROLLER
When connecting source components, or making any connections, be sure that the C-6 Controller
and all system devices are turned OFF and disconnected from AC power to prevent electrical
shock and to avoid possibly damaging components.
Source Components
Audio/Video – Use one quality RCA to RCA type audio/video cable with gold plated connectors
for each A/V source component. Use a stereo cable if the source is audio only. Connect the LEFT
and RIGHT audio outputs and COMPOSITE VIDEO output of each source component to the
LEFT and RIGHT audio inputs and COMPOSITE VIDEO inputs on the C-6 Controller for sources
1-5.
Zone Connections
Keypads/Speakers
As described in the section on Wiring, the Speaker/Keypad Terminals are specially configured for
Phantom Control that combines speaker level audio signals, keypad control signals and power for
the keypads all on the same wire. Special care must be used in making the Speaker/Keypad
connections.
1. Using four conductor stranded wire, strip approximately ¼” of insulation from each conductor.
Twist the strands until tight.
2. Connect the bare wires to the plug-in four terminal screw connectors included with the C-6
accessories. Be sure to maintain proper polarity from the RIGHT+, CONTROL, COMMON and
+LEFT terminals for each zone output. Be sure there are no loose strands sticking out that
could cause a short.
Video
Connect Zone Video Out to quad shield coaxial cable for any zone with a TV or video display.
Tuner
Antennas
FM 75 OHM– Use the included 75 ohm antenna. Connect to the 75 ohm F-type FM Antenna
terminal. Spread the ‘arms’ of the antenna and attach as high as possible on the back of a wall
unit or equipment rack as possible for best reception.
AM – Use the included AM loop antenna. Connect to the AM Antenna two position spring clip
terminal. Polarity is not critical. Position as needed for best reception.
IR Emitters
Sources 1-5 – Use any standard IR emitter with a 3.5mm mini-phone plug for each source
component. Plug emitters into appropriate source IR output jack for sources 1-5. (If the CD player
is source 1, plug the emitter for the CD player into the emitter jack for source 1.) Polarity: Tip =
signal; sleeve = ground.
13
NOTE 1: IR outputs 1-5 are routed IR outputs. When source 1 is selected, only the emitter
connected to IR 1 out will flash.
NOTE 2: IR emitters are available as infrared (no flash) or visible/infrared (red flash). Either will
work. The visible/infrared emitters are recommended in that they give a visual confirmation of IR
output and can be helpful when troubleshooting.
All – Use any standard IR emitter with 3.5mm mini-phone plug to control a single common
device. (IR controlled lights, drapes, lifts, screens etc.) If there is more than one common device,
use a 3.5mm mini-phone plug with pig tail to connect to the IR and ground input terminals on an
amplified IR connecting block to drive additional emitters. Polarity: Tip = signal; sleeve = ground.
NOTE: The ALL IR output will output IR when any keypad or R-1 button programmed with an IR
command is pressed for any source in any zone.
Paging
The C-6 PAGE feature allows several options depending upon the particular system setup. The
Page feature utilizes the MUTE, PAGE, VIDEO and AUDIO inputs grouped on the back panel of
the controller. The paging function also requires some configuration in the Controller Setup Menu.
Some suggested paging options are:
1. Use the 12VDC MUTE Input to mute zone audio as configured in the Controller Setup Menu,
triggered by a 12V input from a device such as a doorbell or telephone system.
2. Use the 12VDC PAGE Input to switch zones to the Page Audio input as configured in the
Controller Setup Menu to allow whole house paging through the speakers connected to the C-6
Controller using a telephone system with a line level audio output.
3. Use the 12VDC PAGE Input to switch zones to the Page Video input as configured in the
Controller Setup Menu to show a front door security camera when triggered by 12VDC from a
doorbell.
4. Use the 12VDC PAGE Input to switch classrooms or offices to a microphone and camera to be
used by a school principal or corporate executive to address students or employees.
Audio – Connect one RCA to RCA mono audio cable from a line level audio output on the
telephone system or device to be used for paging to the PAGE AUDIO IN on the C-6 Controller.
Video – Connect one RCA to RCA shielded video cable from a composite video output from a
security camera or other video device to be displayed in PAGE mode to the PAGE VIDEO IN on
the C-6 Controller.
Mute – Connect one 2.1mm coaxial plug from the mute jack on the C-6 to the control voltage
output terminal of the device to be used to trigger page mute. Be sure to maintain proper polarity
from the +12V and Ground terminals on the control out to the 2.1mm coaxial plug. Polarity: Pin =
+12VDC, sleeve = ground.
Page – Connect one 2.1mm coaxial plug from the page jack on the C-6 to the control voltage
output terminal of the device to be used to trigger page audio/video. Be sure to maintain proper
polarity from the +12V and Ground terminals on the control out to the 2.1mm coaxial plug.
Polarity: Pin = +12VDC, sleeve = ground.
RS-232
Connect and secure one DB9 cable to the RS-232 port on the C-6 and to the appropriate RS-232
port on the control device. DB9 Pinout: Pin 2: Tx (Transmit), Pin 3: Rx (Receive), Pin 5: GND
(Ground). See section: RS-232 Protocol for additional information.
Trigger
The Trigger terminal outputs 12VDC @ 100mA when any zone on the C-6 Controller, X-1 or X-2
Expansion Controllers is ON. This control voltage can be used to trigger voltage controlled lifts,
screens, drapes or switched AC outlets.
1. Using two conductor wire, strip approximately ¼” of insulation from each conductor. Twist the
strands until tight.
2. Connect the bare wire to the plug-in two terminal screw connector included with the C-6
accessories. Be sure to maintain proper polarity from the + (+12VDC) and – (ground) terminals

The Nexus C-6 System is expandable to up to 18 Zones. There are two Expansion Controllers
that are used for expansion. The X-1 expands a C-6 system for zones 7-12 and the X-2 expands
the system for zones 13-18.
Audio, Video and Control signals as well as System information such as ‘Group’ data are all
transmitted via a 52 pin ribbon cable making expansion easy without having to make additional
A/V and control connections.
Once programming and setup have been done in the C-6 Controller for Tuner setup, IR
commands, Source Naming and Input Trim they become universal to the system regardless of
the number of zones. The only additional steps required when adding Expansion Controllers are
Zone Naming, and configuring the added zones for Zone Mute and Paging.
Expanding Zones 7-12
Connect one end of the 52 pin ribbon cable included with the X-1 Expansion Controller to the
LOWER 50 pin Expansion Buss Port on the X-1. Connect the other end of the ribbon cable to the
Expansion Buss Port on the C-6 Controller. Make Keypad/Speaker connections and Video
connections as described in ZONE CONNECTIONS AND SETUP below.
Expanding Zones 13-18
Connect one end of the 52 pin ribbon cable included with the X-2 Expansion Controller to the
UPPER 50 pin Expansion Buss Port on the X-1. Connect the other end of the ribbon cable to the
Expansion Buss Port on the X-2 Controller. Make Keypad/Speaker connections and Video
connections as described in ZONE CONNECTIONS AND SETUP below.

Figure 12. Typical Zone Keypad Wiring
ZONE CONNECTIONS AND SETUP
Keypads
As described in the section on Wiring, the Speaker/Keypad Terminals are specially configured for
Phantom Control that combines speaker level audio signals, keypad control signals and power for
the keypads all on the same wire. Special care must be used in making the Speaker/Keypad
connections.
1. Using four conductor stranded wire, strip approximately ¼” of insulation from each conductor.
Twist the strands until tight.
2. Connect the bare wires to the plug-in four terminal screw connectors included with the C-6
accessories. Be sure to maintain proper polarity on the LEFT+, CONTROL, COMMON and
RIGHT+ terminals for each zone output. Be sure there are no loose strands sticking out that
could cause a short.
3. Plug connector into the Speaker/Keypad Input terminal on the back of the Keypad. Repeat for
all zones.
Speakers
The Speaker Output Terminals output speaker level audio only and use a standard speaker
connection configuration.
1. Using two conductor stranded wire, strip approximately ¼” of insulation from each conductor.
Twist the strands until tight.
2. Connect the bare wires to the plug-in four terminal screw connectors included with the C-6
accessories. Be sure to maintain proper polarity from the L+, L-, R- and R+ terminals for each
speaker pair output. Be sure there are no loose strands sticking out that could cause a short.
3. Plug connector into the Speaker Output terminal on the back of the Keypad. Repeat for all
zones.
Video
Connect the RG6 quad shield coax to a composite video input on the TV or video display. Repeat
for all zones.

PROGRAMMING
C-6 Controller Setup Menu
All system programming is done in the C-6 Controller using the C-6 Controller Setup Menu. No
PC, no software. Other than ‘Group’ and zone treble, mid and bass adjustments, once the
Controller has been programmed, the entire system is ready to go. If the system starts out in a
six-zone configuration using a single C-6 Controller and the homeowner decides to add zones at
a later date, other than adding zone names and setting the zone tone controls, all programming
will already be done!
The Controller Setup Memory is non-volatile so even if the power goes out, the system should not
need reprogramming.
The system setup should always be done prior to taking the system components to the job site.
This will assure that all components are functioning properly. Setting the system up in the shop
will also serve well to prevent overlooking the need for certain parts, pieces, connectors, emitters
etc. This will save time at the job site and help portray an image of professionalism to the client.
Tuner
There are ten Tuner preset memory locations. They can be any combination of AM and FM
stations. The stored band and frequency presets will appear on the Keypad LCDs when Tuner is
selected. To store Tuner Presets:
1. Select TUNER PRESET 1.
2. Press the AM·FM button to select band.
3. Press the MONO·STEREO button to select mode on the Controller Display.
4. Press the SEEK·TUNE button to select TUNE mode on the Controller Display.
5. Use the TUNE UP/DOWN buttons to select tuner frequency e.g. FM 94.7.
6. Press and hold TUNER PRESET 1 for 3 seconds or until P1 appears in the upper left corner of
the Controller Display.
7. Repeat steps 1-6 for Tuner Presets 2-10.
Source Naming
The C-6 provides a simple yet unlimited method of identifying the system source components.
The Tuner input is pre-programmed at the factory. Inputs 1-5 will default to: INPUT 1, INPUT 2
etc until the sources have been named in the Setup Menu. Inputs 1-5 have 40 pre-programmed
source name options such as: CD, DVD, SAT, SKIP, XMRADIO, etc. If you name a source SKIP
that input will be ignored and will sequence to the next input. If a particular source name is not
included in the pre-programmed options, new names can be added. The stored source names
will appear on the Keypad Displays as the inputs are selected from the Keypads or Remote. To
store Source Names:
1. Press MENU to enter the Setup Menu. SOURCE NAMING will appear on the Controller
Display. If the menu cursor (►) appears to the left of Source Naming, Press ENTER. The
Display will change to the Source Naming Window. If ► does not appear next to Source
Naming, use the ▲ button on the Navigation Array to scroll through the menu options to Source
Naming. When ► appears to the left of Source Naming, Press ENTER. The Display will change
to the Source Naming Window.
2. Since Tuner is already set as a system default, with the Programming Brackets [] under INPUT,
[Tun], PRESS ▲ on the Navigation Array. INPUT will change to: [1]. This indicates Input 1 is
ready to be named.

7. Repeat steps 2-6 for sources 2-5.
8. When all Inputs have been named, press MENU. UPDATING KEYPADS will appear on the
Display for a few seconds. The Display will return to the default Tuner Preset Window.
9. Using the SELECT button on any keypad, scroll through the inputs to confirm programming.
Make corrections as necessary.
10. Check all Keypads to confirm Update.
Zone Naming
The individual zones can be named to assist with the ‘Group’ function to temporarily link zones
together when using K-22 Keypads. It is sometimes desirable to be able to control adjacent
rooms or set up a party mode for whole house control and turn multiple zones ON/OFF, select
sources and adjust volume from any of the zones in the group. The process of grouping zones is
much easier when the zones are identified by name rather than trying to guess which room is
Zone 3 or Zone 18. There are 39 Pre-programmed zone name options such as: Kitchen, Master
Bedroom, Atrium, etc. If a particular zone name is not included in the pre-programmed options,
new names can be added. The stored zone names will appear on the K-22 Keypad Displays
when using the GROUP function menu. To name zones:
1. Press MENU to enter the Setup Menu. ZONE NAMING will appear on the Controller Display. If
the menu cursor (►) appears to the left of Source Naming, Press ENTER. The Display will
change to the Zone Naming Window. If ► does not appear next to Zone Naming, use the ▼

return to the Zone Naming Window with ZONE [1] now NAMEd as ATRIUM. (PRESET will
always return to [00].)
5. If a particular zone name does not appear in the presets, zone names can be added by
replacing preset names that will not be used. Example: Name Zone 3, ENTRY. To change a
preset name:
a)In the Zone Naming Window, select ZONE [3].
b)Press ▲ and ▼ to scroll through the presets and stop on a zone name that will not be used.
(KITCHEN 2)
c) Press ► to position the cursor, which will now change to an underscore (_) under the ‘K’.
d)Press ▲ and ▼ to scroll through letters A-Z, numbers 0-9 and one blank space and stop on
the desired character. To change ‘KITCHEN 2’ to ‘ENTRY’ stop on ‘E’.
18
e)Press ► to position the cursor under the next letter and repeat step d.
f) Repeat steps d-e to create a new name up to thirteen characters long. Use the blank space
to delete characters left over from the original preset name if necessary.
6. Press ENTER. ‘NAME SAVED’ will appear on the Display for a couple seconds. The Display
will return to the Zone Naming Window with ZONE [3] now NAMEd as ENTRY.
7. Repeat steps 2-6 for zones 2-18 as needed.
8. When all Inputs have been named, press MENU. UPDATING KEYPADS will appear on the
Display for a few seconds. The Display will return to the default Tuner Preset Window.
9. Use the GROUP and SELECT buttons on any K-22 Keypad to scroll through the Zone Group
Menu to confirm programming. Make corrections as necessary.
10. Check all K-22 Keypads to confirm Update.
Input Level Trim
Different source components can have different output levels. When switching inputs, this will
cause some sources to sound louder than others. The Input Level Trim feature provides a
method of ‘balancing’ the relative loudness of the different sources. Each input can be attenuated
up to 15db in 1db increments from unity gain.
To properly adjust trim, all sources must be connected to their appropriate inputs on the C-6
Controller. They must all be loaded with program material (Radio station, CD, DVD, Video Tape
etc.) and playing. When selecting program material, choose material with similar characteristics.
That is, don’t have the Tuner set to an easy listening station while the CD player is playing high
octane shred metal. Consider also the dynamics of movies from DVD and Satellite where the
sound track can range from low level dialogue to sound of jet engines and explosions. To set
Input Level Trim:
1. Load and play all sources as recommended above.
2. Press SELECT on the Programming Keypad to cycle through all inputs. Make a mental note of
which sources are ‘louder’ than others.
3. Press MENU to enter the Setup Menu. INPUT LEVEL TRIM will be listed in the menu options.
Press ▼ on the Navigation Array to scroll through the menu options to Input Level Trim. When
► appears to the left of Input Level Trim, Press ENTER. The Display will change to the Input
Level Trim Window.
4. The Input Level Trim Window will default to [TUNER].
5. Press ► in the Navigation Array. The Programming Brackets [] will move to LEVEL: [0dB].
6. Press ▲ and ▼ in the Navigation Array to adjust the input level as needed.
NOTE: Input Level Trim adjustments cannot be monitored while in Setup Menu. The settings
must be stored and the Controller must be in a normal use mode to cycle through the inputs to
monitor changes in Input Trim Levels.
7. Press ◄ or ► to return the programming brackets to [TUNER] (or current input).
8. Press ▲ or ▼ to navigate to the previous or next input.
9. Repeat steps 5-8 for Inputs 1-5.
10. Press ENTER when the desired trim levels have been set. ‘SETTINGS SAVED’ will appear
on the Display for a couple seconds. The Display will return to the Setup Menu with Input Level
Trims adjusted.
11. Using the SELECT button on any keypad, scroll through the sources to confirm equal relative
audio levels from all sources. Adjust as needed.
12. Press MENU to return to the default Tuner Preset Window.
Page/Mute
The C-6 can be used for whole-house paging when used with an appropriately featured
telephone system or microphone preamp having a line level audio output and 12VDC control
output. It also has a zone mute function that can be used to mute selected zones with a 12VDC
control input. Both features, Page and Mute have a variable timeout of 1-60 seconds, to set how
long the selected source will be interrupted when triggered by a 12VDC pulse. To program Page
and Mute functions:

[10] Sec. (All zones default to 10 seconds for both functions. If [N] is selected for either function in
any zone, the function will be inactive for that zone.)
11. Press ▲ or ▼ to adjust the PAGE TIMEOUT. (Page timeout can be set from 1-60 seconds.)
The timeout setting will affect all zones set for paging.
NOTE: Page timeout can be used to convert a 12V pulse to a page timeout up to 60 seconds. A
constant voltage will ‘hold’ the page function as long as voltage is present on the PAGE terminal.
For constant voltage, set page timeout to 0 seconds or additional seconds will be added to page
timeout after the voltage has been removed.
12. Press ► to advance the Programming Brackets to set MUTE TIMEOUT duration.
13. Press ▲ or ▼ to adjust the MUTE TIMEOUT. (Mute timeout can be set from 1-60 seconds.)

3. Press ENTER to return to the Setup Menu or MENU to return to the default Tuner Window.
IR
The C-6 Controller is programmed at the factory for system functions such as ON/OFF, Source
Select, Volume UP/DOWN etc. To control the common source components, IR commands for
those devices must be programmed into the C-6. This is a simple process that should only take a
few minutes.
Before programming IR commands, the source components to be used (CD, DVD, SAT, etc.)
should have AC power, have all audio and video connections complete. IR emitters should be
plugged into the appropriate IR out jacks and attached to the IR windows on the components to
be controlled. (The IR emitter jacks are routed outputs so the IR emitter plugged into the IR 1 jack
should be attached to the source connected to Input 1. The IR emitter plugged into the IR 2 jack
should be attached to the source connected to Input 2, etc.)
Programming IR commands by source makes it easier to keep track of what brand/device codes
are being learned and helps avoid missing commands.
Once commands have been learned, always test the commands to be sure they have been
properly learned and that the play button is outputting a play command and not the drawer open
command. To program IR commands:
1. Press PROGRAM on the C-6 front panel. The PROGRAM LED will illuminate RED. The IR
Programming/Zone 1 Keypad on the front panel will turn ON. The Controller Display will change
to the IR Programming Window Menu default: [1] TEACH [2] ERASE.
2. With the Programming Brackets on [1] Teach, press ENTER in the Navigation Array. The IR
Programming Window will change to the Programming prompt for Source 1. (If Source 1 is CD
the prompt will show: Source=CD, ? Sel source or func.
3. To program CD commands, press 1 on the Programming Keypad. The LEARN·ERROR LED
will slowly flash RED. The Display will change to: Source=CD,1 Teach code or re-sel. Point the
remote for the CD player directly at the IR WINDOW on the front panel, next to the Program
button and press the 1 button on the remote. The Learn·Error LED will turn solid red or fast
flash red, quickly turn GREEN and then slowly flash green twice. This indicates a learned
command.
4. Press the 2 button (or next function to be learned) on the programming keypad. The Learn LED
will again slowly flash red. The Display will show: Source=CD,2 Teach code or re-sel. Point the
remote for the CD player directly at the IR WINDOW on the front panel, next to the Program
button and press the 2 button on the remote. The Learn·Error LED will turn solid red or fast
flash red, quickly turn GREEN and then slowly flash green twice. This indicates a learned
command.
5. Repeat step 4 for all CD function buttons on the Programming Keypad.
6. To program commands for the next source, press SELECT. The programming prompt will
change to the next source.
7. Repeat steps 4-6 for all sources.
21
8. Press Program or Menu on the front panel. The Display will return to the default Tuner Window.
9. Test all commands on all buttons for all sources. Replace commands as needed.
NOTE 1: The R-1 Remote that comes with the C-6 has Navigation buttons not found on the
keypads. These buttons are programmed using the same steps as the keypads. (Press a button
on the R-1, followed by a button press on the source remote for the IR command to be associated
with that button.) Once familiar with the process, it may be easier to program all IR commands
using the remote instead of the keypad. This allows programming all of a given sources buttons
at once rather than bouncing back and forth from the keypad to the remote.
NOTE 2: If programming using the R-1 instead of the Programming Keypad, use quick taps on
the R-1 to prompt the Controller in learning mode. Holding the remote buttons down too long will
cause the Controller to recognize R-1 commands, return to a normal operational mode and
attempt to execute to the command. The R-1 remote should be aimed at the IR Window on
the built in keypad on the front of the C-6 not at the IR Learning Window.
NOTE 3: Starting with version 1.91, there are 25 more buttons that can be assigned IR
commands which are not on the keypad, or the remote. These buttons are available as a CCF file
for the Philips Pronto™ series of remote controls. Please contact Nexus if you would like to get
the CCF file.
Power Management of Common Source Components
The C-6 Controller can be programmed to automatically turn the common source components on
when any zone is turned on and turn them off when the last zone is turned off. The programming
is done with a slight variation of IR command programming on the power on/off button.
There are two memory locations associated with the power on/off button for each source
component. One is for an ON command, the other is for an OFF command. All of the source
power on commands will be issued via the IR emitter outputs when any zone in the system is
turned ON. All of the source power off commands will be issued via the IR emitter outputs
approximately 10 seconds after the last zone has been turned off.
If using source components with toggle IR commands (same command turns the device ON and
OFF) program the power command into both locations. If using components with discrete
ON/OFF commands, program ON to the ON location, and OFF to the OFF location. If using
components using RC-5 format codes, the learning processor will recognize the format and
separate the two commands. Simply press the power button on the remote once at step 3 below
and again without pressing any other button on the remote at step 4 below, to teach the ON/OFF
commands to the appropriate locations. To program source power commands:
1. Press PROGRAM on the C-6 front panel. The PROGRAM LED will illuminate RED. The IR
Programming/Zone 1 Keypad on the front panel will turn ON. The Controller Display will change
to the IR Programming Window Menu default: [1] TEACH [2] ERASE.
2. With the Programming Brackets on [1] Teach, press ENTER in the Navigation Array. The IR
Programming Window will change to the Programming prompt for Source 1. (If Source 1 is CD
the prompt will show: Source=CD,? Sel source or func.
3. Press the power button on the Programming Keypad. The LEARN·ERROR LED will slowly
flash RED. The Display will change to: Source=CD,OFF Teach code or re-sel. Point the remote
for the CD player directly at the IR WINDOW on the front panel, next to the Program button and
press the power, or OFF button on the remote. The Learn·Error LED will turn solid red or fast
flash red, quickly turn GREEN and then slowly flash green twice. This indicates a learned
command.
4. Press the power button on the Programming Keypad again. The Display will change to:
Source=CD,ON Teach code or re-sel. Point the remote for the CD player directly at the IR
WINDOW on the front panel, next to the Program button and press the power, or ON button on
the remote. The Learn·Error LED will turn solid red or fast flash red, quickly turn GREEN and
then slowly flash green twice. This indicates a learned command.
5. Repeat steps 3-4 for all sources.
6. Press Program or Menu on the front panel. The Display will return to the default Tuner Window.
22
7. Test power commands by turning all zones OFF. All components should be OFF. (If not,
manually turn them off.)
8. Turn ON a single zone. All sources should turn ON.
9. Make changes to ON/OFF locations under the power button for sources as needed.
Macros (Version IR1.7 and up)
For each of the 5 external inputs on the C6, there are 17 buttons on the keypad, and an additional
9 buttons on the remote control to which macro sequences can be assigned. This allows each
source to have up to 26 macros assigned to it for a system total of 130 macros. Each button can
have up to 5 keys assigned in its macro. When one of these buttons is pressed, one of two things
happens; If there is no macro assigned to the button, then the IR command for that button is
reproduced. If there is a macro assigned to the button, then the IR command for each key in the
macro (up to 5) is reproduced. Shown in figure13 are the keys on the K-22 and R-1 remote that
can have a macro assigned to them. These are the only keys that can be included in a macro. A
macro assigned to a key can have itself as part of its macro. Please note that since a macro is
just a sequence of other keys, any IR commands you want to include in a macro must already be
programmed to a key for that source. To learn how to program IR commands into the C6, please
refer to page 21 of this manual.
These are the keys on the K22 and R-1 remote to which macros can be assigned.
They are the only keys that can be included in a macro.
Lets go through an example of creating a channel preset for a satellite receiver connected to
input 1, and we want to have a preset for channel 912 that will be called by pressing button ‘1’ on
the K22 (or remote).
Step 1.
For input 1, teach all the IR commands into the C6 main unit. For specific instructions on IR
programming, please see the section on IR programming on page 21 of this manual. During IR
programming make sure to teach the IR commands for all the number commands from the
23
satellite remote to the number buttons on the C6, as these IR commands will be used in our
macros.
Step 2.
Now that we have taught all the necessary IR commands to the C6 we can start to create the
macro. As an example, we want button ‘1’ on the K22 to recall channel 912 on the satellite
receiver;
-
Press the menu button on the C6 and select the menu option called Macros using ▼ on
the navigation array, then press enter.
Select the input we are going to assign macros to with ▲ or ▼ buttons. In this case, input
1 is already selected for us.
Press ► on the Navigation Array to highlight KEY, and then press ‘1’ on the built in
keypad of the C6. ‘Num 1’ will display under KEY showing us which key we are assigning
the macro to.
Press ► on the Navigation Array again to highlight MACRO and press the numbers 9 1 2
on the built in keypad. If you make a mistake, press ◄ to backspace.
Press the Enter key on the navigation array to save the macro.
Keep entering macros for other presets if you so desire.
When you are finished entering macros, press the menu button. You will see another screen
appear to adjust the macro delay. This is the amount of time the system waits in between sending
out the individual IR commands in all macros. It should be left at its default value of 0.3 seconds
unless you have reason to change it. To change the delay, use the ▲ or ▼ buttons and then
press the enter key. To exit without changing the delay, press the menu key.
That’s all there is to creating macros. Now when you are listening to the satellite, you can call up
channel 912 simply by pressing number 1 on the keypad.
Erasing Macros
If you want to erase any macros you have created, call up the saved macro in the menu, highlight
the word MACRO, then use ▲ or ▼ to erase the macro, and then press enter to save your
changes. Specific instructions follow:
-
Press the menu button on the C6 and select the menu option called Macros using ▼ on
the navigation array, then press enter.
Select the input we are going to erase macro(s) from with ▲ or ▼ buttons.
Press ► on the Navigation Array to highlight KEY, and then press the key on the built in
keypad of the C6 for the macro key you want to erase. Alternatively at this stage you can
also use ▲ or ▼ to scroll through the keys for this input.
Press ► on the Navigation Array again to highlight MACRO and press ▲ or ▼ on the
navigational array to clear the entry.
Press the Enter key on the navigation array to save the cleared macro.
Keep clearing other macros using the same steps, or press Menu twice to exit.

RS232 PROTOCOL
The C-6 Controller has an RS-232 port that allows the system to be controlled with a touch
screen controller or become a sub-system in a whole-house control package. This allows system
operation such as turning on certain zones for background music when the alarm system is
deactivated. Conversely, a command can be sent to turn all zones off when the alarm system is
activated.
The C-6 Serial Port allows full control of all system functions. In addition to being able to control
the C-6, X-1 and X-2 Controllers ‘on board’ functions (on/off, input select, etc) RS-232 control
includes control of the Tuner and other source components. When the C-6 ‘sees’ a command for
one of the on board functions, it responds accordingly. When it sees a command such as CD
play, the incoming RS-232 command is interpreted in a similar manner to a keypad button press
and the C-6 will output the appropriate corresponding IR command.
The Serial Port on the C-6 uses a female DB9 connector wired in a DTE configuration. Tx
(transmit) = pin 2, Rx (receive) = pin 3, Ground = pin 5. Communication settings are 9600 baud, 8
bits, no parity, no handshake.

Each command must be terminated with a carriage return: <cr>. If an invalid command is sent,
the C-6 will respond with ERR. If a valid command is sent, the C-6 will respond with OK unless it
is a query type command, in which case the C-6 will respond with information. Every response
from the C-6 is terminated with CR/LF.
The C-6 sends out unsolicited information whenever a keypad is operated. The syntax is the
same as that used for controlling the C-6. For instance, if someone turns on Zone 1 via a keypad,
the C-6 will transmit Z011 out of the serial port. The string will be terminated with CR/LF.

Ask the C-6 if a zone is on or off. The C6 will respond with Zxx1 for zone on, and
Zxxo for zone off. Xx is the zone number
queried.
Turn all zones all zones off. If Expansion
Controllers are connected, their zones
will also be turned off.
Similar to selecting a source on a remote
keypad. T=tuner. 01-05=inputs 1-5.
Ask the C-6 what input a zone is on. The
C-6 will respond with Sxxy, where xx is
the zone number queried and y the input

Create a group. The source and volume of
the group should be set with the GRS and
GRV commands previously. Bitmask is
the decimal equivalent of a binary
weighted sum of the bits which are set (in
the group). Example: to add zones 1 and 3
to a group, use GRP050000<cr>
Ask the C6 for group info. If no group is
set it will respond with GRP000000.
Otherwise it will respond with a decimal
equivalent of a binary weighted sum of
the bits which are set (in the group).
Example: if there is a group with zones 2
and 4 in it, GRP? with respond with
GRP120000.
Set the input for the group. If there is
already a group, their source will change.
If there is no group, nothing will happen,
but any subsequent groups created with
GRP command will set their inputs to the
input specified by GRS. Note: Groups
created via keypad will use the source
that the keypad is set to, not what the
GRS command set.
Set the volume for the group. If there is
already a group, their volume will
change. If there is no group, nothing will
happen, but any subsequent groups
created with GRP command will set their
volume to that specified by GRV. Note:
Groups created via keypad will use the
volume that the keypad is set to, not what
the GRV command set.

Description
Ask the C6 what source the group is set
to. If there is a group, it will report back
what source it is set to. If there is no
group, it will report what source will be
set if you create a group using RS232
group commands. Note: this is not the
source that will be used if a group is
created via keypad, as the group will then
use the keypads source setting.
Ask the C6 what the volume setting
would be if a group were to be created via
RS232 group commands. Note: this is not
the volume that will be used if a group is
created via keypad, as the group will then
use the keypads volume setting.
Add a zone to an existing group. The
zone will be turned on, Its source will be
set to the same as the other zones in the
group, and its volume will be set to the
value set by the GRV command.
Remove a zone from the group. The
zones status will not change.
Further explanation of the GRPxxyyzz command
The three values xx, yy, and zz in the command refer to the C6 (zones 1-6), the X-1(zones 7-12), and the
X-2(zones 13-18) chassis respectively.
xx byte:
zone
1
weight 1
2
2
3
4
4
8
5
16
6
32
To calculate the xx byte, add the weights together for the zones you want to be in the group.
Example: to add zones 2, 3, and 5 to a group, Add their weights 2+4+16 = 22. xx now equals 22.
yy byte:
zone
7
weight 1
8
2
9
4
10
8
11
16
12
32
To calculate the yy byte, add the weights together for the zones you want to be in the group.
Example: to add zones 7, 10, and 11 to a group, Add their weights 1+8+16 = 25. xx now equals 25.
zz byte:
zone
13
weight 1
14
2
15
4
16
8
17
16
18
32
To calculate the zz byte, add the weights together for the zones you want to be in the group.
Example: to add zones 15, 17, and 18 to a group, Add their weights 4+16+32 = . xx now equals 52.
Now that xx, yy, and zz are calculated, you can add all these zones to a group by issuing the RS232
command GRP222552. You could also create a group by using the GRP+xx command repeatedly, but it
takes a lot longer to setup a group that way.

ADVANCED WIRING FOR EXTERNAL POWER AMPLIFIERS
The following section provides options for adding high power amplifiers in zone specific
applications. The basic application uses resistors on the left and right speaker level outputs to
create a stereo line level signal that can be fed into external amplifiers.
Applications 1&2 provide stereo line level output at the C-6 Controller from the Zone
Keypad/Speaker Output Terminal. Application 3 provides stereo line level in the remote zone
from the Keypad Speaker Level Output.
All Applications still provide zone control from the K-8 or K-22 Keypads and R-1 Remote.
Take extra precautions in checking all connections prior to powering up the system components
and turning on a zone using one of these applications. Severe damage can occur from improper
connections.
Figure 15. Application 1 Using an External High Power Amplifier
Application 1
This application allows using an external amplifier at the system head end utilizing the house
wiring and keypad input and output terminals. This application requires configuring the amplifier
output to adapt to the Phantom Control wiring scheme up to the zone keypad. The zone keypad
will output ‘normal’ speaker output. (L+,L-;R-,R+).
29
Figure 16. Application 2 Using an External High Power Amplifier
Application 2
This application allows using an external amplifier at the system head end utilizing dedicated
speaker wire to the zone speakers. This application only requires a two conductor wire for the
zone keypad. Speaker connections from the amplifier to the zone speakers are standard
configuration.
Figure 17. Application 3 Using an External High Power Amplifier
Application 3
This application allows using a high power amplifier in a remote zone. The house wiring from the
C-6 Controller to the zone keypad is Phantom Control configuration. The zone keypad speaker
30
level output is adapted to line level and fed into a local amplifier. Speaker connections from the
amplifier to the zone speakers are standard configuration.
