SPEAKER CONNECTIONS  
Your source inputs are located at the top left corner of the  
back panel. Although the source input names are silk  
screened on the back of the CA, these names are for refer-  
ence only. Any type of source equipment can be connected  
to any input. Connect each source output, left and right,  
using quality signal cables / patch cables. Label each cable  
the name of your source and the input number of the CA  
you have selected. Repeat until all sources are connected.  
List them down below.  
Each speaker connection on the back panel corresponds to  
one room/zone. Wire your speakers by first removing the  
connector for the chosen zone. Using wire strippers, strip  
back 1/4" of the end of the wire. Insert the proper polarity,  
left + to left +, left- to left- etc., until all wires are connect-  
ed in each zone output. Label each wire with the room name  
and zone number. Write down the room name to the zone  
number below. Note: We recommend 8 Ohm minimum  
speakers for each zone. However, speakers as low as 4 Ohm  
can be safely used in up to two zones, if necessary.

• In order for your CA to transmit the IR signal from the  
channel is desired, connect one or more zones of the CA4.4pi  
to an external amplifier. Using standard RCA connectors,  
wire from the pre-amp outputs of the CA4.4pi to the ampli-  
fier's inputs. A typical application for more power is when  
connecting an outside zone where the audio power require-  
ments would be much greater than an inside zone.  
keypads to a source, an emitter must be connected from  
the IR outputs marked 1-4. Each of these outputs is wired  
in series and must be connected in consecutive order. For  
example, the #1 emitter output must be connected in  
order for the #2 emitter output to transmit the IR com-  
mand. NOTE: All IR outputs are common  
• Connect each 845.1 mini-emitter to the IR output.

KEYPAD CONNECTIONS AT CONTROLLER  
• Each keypad connection on the back panel of the CA-Series Master  
List 4 – Room names should be written below.  
Controller corresponds to the room / zone number chosen for your  
speakers. Each zone operates independently, so it is very important to  
connect the keypad to the correct zone keypad input.  
Zone 1 _________________  
Zone 2 _________________  
Zone 3 _________________  
Zone 4 _________________  
• On List 4 (opposite) copy down the room name to the zone number  
from List 3 on pg 6. NOTE: the keypad and the speakers in each room  
must be hooked to the corresponding numbered zone.  
• Remove the connector and strip 1/8" off each end of the wire insula-  
tion. Connect each wire 1 thru 8 using a small jewelers screwdriver.  
WIRING RUNS UP TO 100 FEET  
WIRING RUNS FROM 100-200 FEET  
For wiring runs of up to 100 feet in length, we recommend  
the use of CAT-5 wire. It is inexpensive and color coded for  
ease of installation. Due to the qualities of CAT-5 wire, when  
using it for keypad control wire with the CA-Series, it is rec-  
ommended to use the following color code for maximum  
performance.  
For wiring runs exceeding 100 feet and extending up to 200  
feet, we recommend the use of 8-conductor 22 AWG strand-  
ed wire such as Russound MCW2418.  
If using 22 AWG wire, the order in which you wire is not  
important as long as you wire in the same order at both the  
CA unit as well as the keypad. Use List 5 (below) to write  
down the wire you use for each pin number.

• Check whether or not you can route the wire to the loca-  
tion you have chosen.  
• Purchase retro-fit plastic junction boxes (min. 20 cubic  
inches) or p-rings and cut in the boxes using a key-hole  
saw or sheetrock knife/hand saw.  
The CA-KP.2 and CA-LCD come with 110 punchdown termi-  
nals. These terminals are quick, easy to install and provide a  
strong connection. Punchdown terminals require the use of a  
punchdown tool. One has been provided with this kit.  
• If you are installing the optional DSC keypad you will  
need to use a double-gang electrical box. If you are  
installing the CA-LCD, DSC and the optional DAN keypad  
you will need to install a triple-gang electrical box.  
Press wires into punchdown terminal with punchdown tool  
as shown in Figure 12.  
• If you feel uncomfortable cutting into your walls and  
running wire through the walls, seek help from a profes-  
sional installer or an electrician.  
Figure 12 – Punching Down Wires  
• Route the wire to the junction box from the CA location.  
• If using 22 AWG wire, connect each wire to the correct  
position 1 thru 8 using the included punchdown tool.

SETTING THE KEYPADS  
SRM-2.1 SPEAKER RELAY MODULE OPTION  
Before a keypad is installed into the j-box, turn on the  
power so that you can operate the keypad.  
The optional SRM-2.1 module works with CA-LCD keypad’s  
12V trigger output. This unobtrusive wall-mount device  
allows you to automatically switch to whole house audio in  
a zone containing existing audio equipment. Example: In a  
bedroom with a stereo system, the stereo system would be  
the default. When you turn on the bedroom's zone at the  
keypad the whole house audio system takes control of the  
existing stereo speakers.  
CA-LCD Only: The amber and the green backlight brightness  
can be individually set. Note the brightness controls are  
located on the side of the keypad. Adjust to the desired  
brightness the backlight that first comes on. Press and hold  
the lamp button on the front of the keypad until the back-  
light switches to the other color. Adjust the brightness for  
the selected color.  
If you are using the optional SRM-2.1 speaker relay module,  
wire the +, - terminals of the CA-LCD to the SRM-2.1 +, -  
terminals.  
Both CA-LCD and CA-KP.2: The maximum volume and the  
balance should also be set at this time.

left on at all times. The unit will consume very little power  
unless the zones are on and active. The unit has a stand-by  
mode when the zones are inactive.  
1) Power On / Off: This knob on the CA KP.2 keypad con-  
trols all functions except for the IR management. To turn  
the unit on, simply turn the control knob clockwise. You  
will feel and hear a click verifying that the unit has been  
activated. The lights on the keypad will also illuminate to  
verify the zone is now on. Note - The CA front panel  
zone-management lights also informs you which zones  
are On or Off.  
Zone Indicators: The zone indicator will light either red  
for off or green for on. The zones can only be turned on  
from the keypads. All functions are accessed through the  
keypad only.  
2) Volume Up / Down: Once the unit is on, the knob can be  
used to adjust the volume. To adjust the volume up, turn  
the knob clockwise, and to turn the volume down, turn  
counter-clockwise.  
3) Source Selection: By pressing the knob, the zone will  
scroll through the four sources connected to the CA. The  
keypad has four backlit windows that indicate the source  
selected.  
4) IR Source Control: The IR window repeats all source com-  
mands from the source component's remote (or optional  
DSC/DAN keypads) through the CA and 845.1 emitters.  
Most IR remotes have a range of 20' at an angle of 60-65  
degrees.

troller and on to the source equipment. It will receive IR  
signals from 38KHz to 56KHz. To control the functions of  
the CA-LCD keypad, use the CA Remote control (see  
Figure 6). The CA remote control will operate the lamp,  
source selection, volume up / down and room on / off.  
8) IR Confirmation LED: This LED will flash to confirm the  
reception of an IR signal from a remote control through  
the IR receiver.

TROUBLESHOOTING  
KEYPAD WIRING PROTECTION CIRCUIT  
ELIMINATION OF BALANCE LINE  
To provide protection for incorrect keypad wiring, this CA-  
Series product is equipped with a short circuit protection  
device. In the event of a keypad cable short, or incorrect  
keypad wiring, this device will automatically interrupt power  
to all keypad ports.  
The following diagram shows how resistors may be used at  
the Keypad connection on the rear of the CA master control  
unit, to provide 2.5VDC to the balance control line for cen-  
tering. This circuit will stabilize the balance line input and  
keep it centered. They can be used to free up one of the 8  
required conductors if one is open, shorted or if an extra  
conductor is needed for a secondary IR receiver’s signal in  
that zone. Position #1 is GND, #3 is 12VDC, #8 is Balance.  
Once installed, if the keypads connected to your CA-Series  
product will not turn on, the short circuit protection device  
may have been activated. Please take the following steps to  
troubleshoot the system.  
CA Keypad Connector @ Rear of Processor  
1) Turn off the power switch on the front of the CA-Series  
controller.  
820 Ohm 1/4w  
3.9K Ohm 1/4w  
2) Disconnect all keypad connections from the rear of the  
controller.  
3) Check the wiring configuration for each keypad, checking  
both ends (the CA unit and the CA keypads) of the CAT-5  
keypad cable.  
4) If incorrect connections were found, correct the wiring  
and reconnect the keypads to the controller. After the  
controller has been powered off for at least 15 seconds,  
turn on the power switch of the CA-Series controller.

TROUBLESHOOTING  
COMBINING ADDITIONAL IR RECEIVERS  
When combining a CA Series multi-source controller and a  
secondary IR system together, it needs to be done after the  
CA System. The IR information from the keypad is on Pin #2.  
This signal is demodulated at the keypad and is re-modulat-  
ed at the processor then sent to the emitter out-puts.  
Combining a modulated IR signal to this lead (#2) will not  
work because it is already modulated. The following method  
should be used to assure correct integration with such com-  
ponents.

The emitter outputs on the CA Series are wired in series, so  
#1 must be used first in order to obtain a signal. Simply plug  
the IR linking cable supplied with the CA product into emit-  
ter port #1. and plug the other end into the Russound 857  
IR Connecting Block’s “IR Common In. The secondary IR  
receiver can either be wired to the terminal block as shown  
or plugged into the “IR Reciever In” via a 1/8” mini-plug. The  
emitters that would have been connected directly to the CA  
system will now be plugged into the connecting block.

845.1 MICRO EMITTERS  
TO IR CONTROLLED  
EQUIPMENT  
This method combines the modulated IR signal at the con-  
necting block then distributes it to the four emitter ports.  
The power supply shown (846C) would only be required if  
the second IR receiver(s) needed it.  
This method would also be used when connecting multiple  
CA systems together. The IR Link is only designed for two CA  
systems being that it conveys demodulated IR data between  
the systems.
