C-612 INSTALLATION INSTRUCTIONS
INTRODUCTION
Welcome to Nexus Audio Systems and congratulations on your purchase of the C-612 Multi-Zone
Controller.
The C-612 supports six independently operated zones and infrared (IR) control of four external line level
audio source components. Two Audio Input Module Option Bays provide additional source input capability
for devices such as iPods and XM Tuners. The C-612 also features a built-in AM/FM Tuner with twenty
Channel Presets.
Each zone features a solid 50 Watts per channel stereo amplifier for clean, unfatigueing listening. Each of
the routed source IR outputs can be set for 38 KHz or 56 KHz output for optimum source control. The unit
includes a RS-232 Port that allows the C-612 to be controlled with a touch-screen or easily integrated with
other home automation control systems. The Nexus C-612 provides a mute function that can integrate
with a doorbell or telephone system to ensure no important call or visitor is ever missed, and audio paging
for whole-house voice communication. The system is expandable to 12 zones using two C-612
Controllers.
Source power management is referenced to system status with all sources being automatically turned on
when the first zone is activated and turned off when the last zone turns off. Programming power
management takes only seconds and requires no additional connections or components.
The C-612 Keypads provide simple, intuitive control of zone power, source selection, source control,
volume, treble and bass and tuner functions. The blue backlit high-resolution keypad LCD indicates zone
status, source selection, volume as well as tuner frequency and preset. Zone names, source names and
tuner preset names are all configurable in the C-612 Setup and are all displayed on the Keypad LCD.
The C-612 features six programmable buttons that can be used for basic device control such as chapter
skip, stop or pause for transport devices and tuner up/down or preset up/down for tuners. The keypad
features a built-in infrared receiver that can be used with the included R-3 Remote Control or any properly
programmed IR remote for additional flexibility and armchair control. The R-3 includes an additional 23
buttons that are programmable by source to include vital source control commands.
The Zone Sharing feature allows up to three zones to be linked together for ease of use in common areas
that would typically have the same source selected and playing. Zone Sharing includes two modes. One
links the zones for power, source and volume, the other has the same source selected in all three zones,
but each zone retains independent power and volume control.
The Nexus C-612 is a flexible, full-featured multi-zone controller that is easy to install, program and
operate. At Nexus that’s our goal. To provide you with well thought-out system components that reduce
the time spent on-site allowing you more time for managing other important parts of your business…such
as selling and installing more Nexus Audio Systems!
Thank you for your support.

DESIGNING AND INSTALLING A C-612 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, for either 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 to 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 and dock/undock the iPod…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 should they 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 or video displays? Be sure to pull all required cabling and
observe all local building and electrical codes.
INSTALLATION
Controller Location
The C-612 should be located at the main termination of all wire and cable runs. The source components
(Tuner, CD, DVD, SAT, Music Server, etc) should also be installed at this location.
The C-612 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-612 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 a placing the unit on a
shelf or another component will inhibit airflow and is not recommended. Additionally, care should be taken
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.
14
Rack Mounting
Figure 7. C-612 Rack Ears
Rack Ears (Nexus Part #RK 3.5) are available as an accessory item that can be ordered from Nexus for
rack mounting the C-612. The Ears mount behind the C-612 Front Panel as shown in Figure 7. The Ears,
when secured to the rack, have the same height as other rack panels and allow use of Middle Atlantic
Trim Strips for a clean finish. To attach Rack Ears:
1. Align Rack Ears to the Chassis Screw Holes in the sides of the C-612. Secure with Rack Ears
Chassis Screws included with Rack Ears.
2. Secure to rack using appropriate rack mount hardware.
NOTE: When rack mounting the C-612 Controller and other system components, it is recommended that
one, one rack space vent panel be used above and below the C-612 Controller to provide adequate
airflow for cooling.
Keypad Location & Mounting
The C-612 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.
15
WIRING
One of the most important aspects of system design and installation is the wiring infrastructure. 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 and control wires for audio and control
as well as coax or other appropriate cable (HDMI over CAT5, etc), for video distribution, even though the
C-612 does not switch video and the system will only initially be used for audio sources. 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.

EXPANDED SYSTEMS
Two C-612 Controllers can be linked together to expand a C-612 system to up to twelve zones. The
fundamental installation and connections are similar to those on a single controller system with a few
minor changes.
Figure 14. Expanded C-612 System
20
Nexlink Connection
This connection allows communication between the Master and Slave Controllers for zone/system status,
system/source power management, page control, mute control and external common source IR control
from the keypads or remotes used in the zones connected to the Slave Controller.
Using a RJ11 patch cable configured in a crossover configuration, connect the Nexlink jack on the
Master Controller to the Nexlink jack on the Slave Controller. See Figure 15b for construction of
cable.
NOTE: Two linked C-612 Controllers must be configured for Master/Slave configuration in the Main
Menu Master /Slave Setup (Main Menu item 10). IR emitter and mute/page connections are made to
the master.
Source Audio
Source audio must be distributed to both the Master and Slave Controller source inputs to have source
audio signals available to all zones.
Use either ‘Y’ adapters or an audio distribution amp to split the line level audio signal from the source
outputs to the source audio inputs on both controllers as shown in Figure 14.
NOTE: If using an A/V Source an audio/video distribution amp is recommended to split the audio
signals to the C-162 Controllers and provide multiple video outs that can be distributed to the zone
video displays and maintain proper signal level.
IR Emitters
The IR Emitter are connected to the Master Controller IR Outputs as done in a single controller system.
The Slave Controller will communicate IR control to the Master via the Nexlink connection. See section:
Connections/IR Emitters for additional information.
Speakers
Speakers are connected to the appropriate Master or Slave Zone Speaker Outs as described in section:
Connections/Speakers.
Mute
The Audio Mute control IN is connected to the Master Controller Mute jack as done in a single controller
system. The Master Controller will communicate Audio Mute to the Slave Zones via the Nexlink
connection. See section: Connections/Mute for additional information.
Page Audio
Page Audio – The audio for paging must be distributed to both the Master and Slave Controller Page
Audio inputs to have the Page Audio signals available to all zones.
Using quality audio cable, jump the Page Audio terminals on the Master Controller to the Page
Audio Terminals on the Slave Controller as shown in Figure 15a. Though polarity from the Page
Audio Source to the Master Page Audio IN is not critical, do maintain proper polarity between the
Master and Slave Page Audio Terminals. Be sure there are no loose strands sticking out that can
cause shorts.
Page Control - The Page Audio Control IN is connected to the Master Controller Page Audio Control
Terminals as done in a single controller system. The Master Controller will communicate Page control
to the Slave via the Nexlink connection. See section: Connections/Page Audio for additional
information.

PROGRAMMING
Programming IR Commands
C-612 System programming takes only a few minutes and provides power management and basic
transport control for the connected sources. Out of the box, the system has default programming for
Controller & Zone ON/OFF, Input Select and Volume UP/DOWN so those functions do not require
programming. When finished, the buttons on the C-612 Keypads and R-3 will have the same functionality.
NOTE 1: IR commands are stored in memory locations in the C-612 Controller that are associated with
the keypad and R-3 remote buttons. When a button on a keypad or the R-3 is pressed, the C-612
recognizes the button location and outputs the associated IR command. If programming a universal
remote for IR control, the appropriate R-3 button IR commands will need to be learned by the universal
remote to trigger system functions and source commands stored in the C-612.
NOTE 2: The programmable keypad buttons can only be programmed for single IR commands with the
exception of the Power Buttons. The Power buttons can be programmed for two commands, (ON/OFF). If
discreet ON/OFF commands are available, teach both as prompted in Learn IR Commands/Source
Power Commands. If only Toggle commands are available, teach the toggle command twice as
prompted. Macros can be created in a separate programming function. See section:
Programming/Macros.
Button Mapping
All buttons on the C-612 Keypad have matching buttons on the R-3 Remote. These buttons only need to
be programmed once, and once programmed, the learned IR commands are available to the keypad and
remote.
The R-3 has additional buttons, not available to the keypads that can be programmed for source IR
control. These IR commands are not learned by the R-3. These commands are learned by the C-612
Controller using the same method as programming the common buttons. Once programmed, when a R-3
button is pressed, the R-3 command will be recognized by the C-612 Controller and the C-612 will then
output the associated source IR command via the appropriate source IR Emitter.
In Figure 16, the white buttons are programmable for the same IR commands on the C-612 Keypads and
R-3 Remote. The gray buttons on the R-3 Remote are only programmable for the R-3. The black buttons
are factory default functions and are not programmable.
Figure 16. C-612 Keypad and R-3 Remote Button Mapping
23
Programming utilizes the R-3 Remote Control, the original manufacturer remotes for the sources to be
controlled and requires that the C-612 Controller has AC power. All sources should be connected and
have IR emitters attached to test commands. Note: in a master/slave configuration, teach the IR
commands into the master only. You may turn off the Slave to void having it responds to commands from
the R-3 remote during programming. To program C-612 source control:

Input Level Trim
The different source components in a system 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 12db in 1db
increments from unity gain.
To properly adjust trim, all sources must be connected to their appropriate inputs on the C-612 Controller.
They must all be loaded with program material (Tuner Channel, CD, DVD, 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.
With all sources playing scroll through the inputs to get a reference to the relative levels of the different
sources. To set Input Level Trim:
1. With the Main Menu open, press 5 or position the cursor in front of Input Level Trim, Figure 29, and

USB
From time to time Nexus Audio will release firmware updates for the C-612 Controller and Keypads.
Sometimes these updates will be improvements to system functionality and sometimes they will be new
feature additions. Updating firmware on the C-612 is done with a USB Flash (thumb) Drive.
Updates can be obtained by contacting Nexus Audio Systems Inc.
The file for the C-612 Controller (if included) will be named ‘C612Vx.xx.bin’. The "Vx.xx" denotes the code
version. Before copying the file to the flash drive, it must be renamed to ‘C612.bin’ or the C-612 will not
32
recognize it. Similarly, the file for the keypads (if included) will be named C612K1Vx.xx.bin. It will have to
be renamed to ‘C612K1.bin’, or it will not be recognized by the C-612.
The USB flash drive to be used for the upgrade can have other files on it, but if there are a lot of files, the
C-612 may take a long time to initialize before the upgrade begins. If the C-612 does not initialize or
download the update, delete the extraneous files, or use another flash drive with less or no files on it.
Upgrading the C-612 Controller
1. Rename, and copy the file ‘C612.bin’ to a USB flash drive.
2. Turn off the C-612.
3. Insert the USB flash drive into the USB port on the C-612 Rear Panel.
4. Turn on the C-612.
5. Wait for programming to complete, as indicated on the Front Panel Display.
6. Remove the USB flash drive, and cycle the power on the C-612.
7. If using a slave chassis, it will need to be upgraded also.
Upgrading the C-612 Keypads
1. Rename, and copy the file ‘C612K1.bin’ to a USB flash drive.
2. As a check, turn the C-612 OFF, then ON, and verify that all attached keypads are properly detected.
(‘1Y 2Y 3Y 4Y 5Y 6Y’ will appear on the Front Panel Display.)
3. Insert the USB flash drive into the USB port on the C-612 Rear Panel. ’USB ready’ will appear on the
Front Panel Display.

RS-232 PROTOCOL
The C-612 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-612 RS-232 Port allows full control of all system functions. In addition to being able to control the
C-612 Controller’s ‘on board’ functions (ON/OFF, input select, etc) RS-232 control also allows control of
the connected source components. When the C-612 ‘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-612 will then output the appropriate
corresponding IR command.
The RS-232 Port on the C-612 is a DB9 female jack. Tx (transmit) = PIN 2, Rx (receive) = PIN 3, Ground
= PIN 5. Communication settings are 9600 baud, 8 bits, 1 stop bit, no parity.
Figure 45. RS-232 Port Pin Out

Each command must be terminated with a carriage return: <cr>. A carriage return is a single, nonprintable character with a hexadecimal value of 0x0D, or decimal 13. This character is represented in this
document by the string <cr> If an invalid command is sent, the C-612 will respond with ERR<cr>. If a
valid command is sent, the C-612 will respond with OK<cr> unless it is a query type command, in which
case the C-612 will respond with information terminated with <cr>. Every response from the C-612 is
terminated with a carriage return.
The C-612 sends out unsolicited information whenever a keypad is operated. The syntax is the same as
that used for controlling the C-612. The information will be terminated with <cr>.
The RS-232 commands for the Nexus C-612 are outlined in a separate document titled "Nexus C-612
RS-232 protocol". Please contact Nexus Audio Systems Inc. for a copy of this document.
35
OPTION BAYS
On the back of the C-612 are two option bays. Looking at the back of the unit, the bay on the left is tied to
input 5, and the bay on the right is tied to input 6. See figure 46.
Slot 1 = Input 5
Slot 2 = Input 6
Figure 46. C-612 option bays.
There are two types of module available:
1. An iPod dock adapter module. This module enables
connection of an iPod dock to the C-612. See figure
to right.
2. An audio input module. This module enables the
addition of extra audio inputs on the C-612. See figure
to right.
MODULE INSTALLATION
The installation of modules in the C-612 is the same regardless of which module is being installed:
1. Turn off the C-612 and unplug the unit from the mains. NOTE: failure to follow this step may
result in injury.
2. Remove the cover of the C-612 by removing the thirteen screws holding it in place. Set the cover
and the screws aside.
3. Remove the cover plate from the option bay in which you want to install a module. The two
screws will be re-used to secure the module being installed.
4. Gently insert the option module through the opening in the back of the C-612, and secure it using
the two screws saved from the cover plate.
5. Inside the C-612 you will see a grey ribbon cable coming from the just installed module with a
black connector on the end of it. Gently push this connector into the socket directly below it on the
large circuit board.
6. If you have another module to install, do it now using the same procedure.
7. Re-install the cover. Make sure all screws are accounted for, and none have made their way
inside the unit.
8. Make all the required connections to the installed module(s), then plug the C-612 in and turn it on.
36
CONNECTING AN IPOD DOCK
Please refer to figure 47 when connecting one or more iPod docks to a C-612. No audio connections
need to be made, as audio is transfered through the DATA I/O cable. When connecting more than one
iPod dock, it is important that the address switches on the rear of the iPod docks are set differently. Using
a small screwdriver, set the address on iPod dock #1 to 0, and set the address on iPod dock #2 to 1.
Figure 47. iPod dock connections
Please refer to Figure 48 when connecting one or more iPod docks on a stacked system. The master has
iPod modules installed, and the slave has audio input modules installed. Audio is passed from master to
slave through the use of RCA patch cords. As in the single chassis system above, each iPod dock needs
a unique address. Using a small screwdriver, set the address on iPod dock #1 to 0, and set the address
on iPod dock #2 to 1.
Figure 48. iPod docks on a stacked system
Using the configuration shown in Figure 48, audio and control of the iPod docks is available from all
twelve zones in the system. Some points to remember when setting up a stacked system; Make sure that
the Master unit is setup to be a master in the menu settings, and the Slave is setup to be a slave. See the
section on MASTER/SLAVE on page 34. Also, in order for the iPod docks to work across all twelve
37
zones, make sure that the iPod inputs are named the same on the master and slave. For example, if input
5 (iPod dock #1) is named "iPod 1" on the master, then it should also be named "iPod 1" on the slave.
Same goes for input 6 (iPod dock #2), it could be named "iPod 2" on both chassis. Please see SOURCE
NAMING on page 27.
