SOURCE INPUT 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 refer­ence 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.

List 1 – Source names should be written below

Input 1 (TUNER) ____________ Input 2 (CD) ____________

Input 3 (TAPE) ____________ Input 4 (AUX) ____________

6

SPEAKER CONNECTIONS

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 connect­ed 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.

ZONE PRE-AMP OUTPUTS (CA4.4PI ONLY)

In applications where more power than the 20 watts per
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 ampli­fier's inputs. A typical application for more power is when
connecting an outside zone where the audio power require­ments would be much greater than an inside zone.

12-VOLT TRIGGER OUTPUT

The 12 volt trigger is engaged when any of the zones are on
and disengaged when the last zone is turned off. The trigger
can be used to engage any 12 volt triggered accessory, such
as a triggered AC outlet or audio amplifier. The connection
for the trigger is made through an 1/8” male mini-plug jack.
The tip is (+) and sleeve is (-).

CONNECTING THE INFRARED COMPONENTS

• In order for your CA to transmit the IR signal from the
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 com­mand. NOTE: All IR outputs are common

• Connect each 845.1 mini-emitter to the IR output.

• Remove the adhesive back and position the IR receiver on
the product you wish to control. Stick the 845.1 emitter
directly over the source components IR window.

CONNECTING THE IR LINK

When two CA Controllers are to be used in an installation,
the IR Link connection is used to pass IR signal between the
two units. Use a 1/8” mini-plug, male-to-male cable (includ­ed) connected from the IR Link on the first CA Controller to
the IR Link on the second CA. When connected, you may
connect your IR emitters to either CA unit’s IR Remote
Output jacks.

KEYPAD CONNECTIONS AT CONTROLLER

• Each keypad connection on the back panel of the CA-Series Master
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.

• 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 insula­tion. Connect each wire 1 thru 8 using a small jewelers screwdriver.

WIRING RUNS UP TO 100 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 rec­ommended to use the following color code for maximum
performance.

WIRING RUNS FROM 100-200 FEET

For wiring runs exceeding 100 feet and extending up to 200
feet, we recommend the use of 8-conductor 22 AWG strand­ed 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.

NOTE: Wiring runs longer than 200 feet are not recommend­ed for the CA-Series Keypads.

List 5 –Wire color should be written below.

INSTALLING THE KEYPADS

• The best infrared remote performance is achieved with
the keypad away from any direct sunlight. Also consider
convenience when choosing a location.

• Choose a place that is easily seen from the position where
a person is most likely to be located.

• Check whether or not you can route the wire to the loca­tion 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.

• 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.

• If you feel uncomfortable cutting into your walls and
running wire through the walls, seek help from a profes­sional installer or an electrician.

• 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.
Refer to List 5.

• If using CAT-5 wire, connect each wire to its correspon­ding color labeled on the punchdown terminal.

• Mount the keypad in the junction box and attach the
Decora plate.

• The CA-KP.2 keypad has source labels for your conven­ience. Insert the label in the keypad keeping the input
number in sequence with the source selected.

• Repeat the above steps until all keypads are installed.

OPERATION

OPERATING THE MAIN UNIT

• Power switch: When the power switch is engaged, the CA
power indicator will be lit an amber color. The CA should be
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.

• 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.

OPERATING THE CA KP.2 KEYPAD

1) Power On / Off: This knob on the CA KP.2 keypad con­trols 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.

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 com­mands 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.

OPERATING THE CA-LCD KEYPAD

OPERATION

1) Display: The LCD panel displays the name of the source
selected and the volume level.

2) Source: The source button is pressed to select one of the
four sources to listen to. Press the source button until the
desired source is selected. The source will be displayed on
the LCD display panel.

3) Volume Up / Down: The UP / DOWN arrows for volume
are used to select the volume level and to select a differ­ent source name after the store button is pressed. If the
button is pressed and held the volume will ramp up or
down.

4) Lamp: The lamp button when pressed and released will
turn on and off the backlight lamp. The backlight color
can be set to amber or green by pressing and holding the
button. The backlight will change from one color to the
other.

5) Power: Turn on or off any zone by pressing the power
button on the front of the corresponding keypad. When
the keypad comes on, it will automatically select the
source that was previously selected and set the volume to
minimum.

6) Store: The store function is used to select and store one
of the 23 preset source names for each of the four
sources. Select the source name that you want to change
by selecting source. Press and hold the store button for
approximately 3 seconds, and the display begins to flash.
Immediately press the UP/ DOWN volume buttons to
select the different source names. After you have selected
the name, press the store button again or wait for it to
stop flashing.

7) IR Receiver: The IR receiver is used to receive commands
from an IR remote control. Remote controls used for the
source equipment will pass through to the main con­troller 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.

KEYPAD WIRING PROTECTION CIRCUIT

To provide protection for incorrect keypad wiring, this CA­Series 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.

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.

1) Turn off the power switch on the front of the CA-Series
controller.

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.

5) If the problem persists, repeat steps above trying each
keypad consecutively.

6) Inadequate ventilation can allow normal heat to build up
and trip the protection circuit.

ELIMINATION OF BALANCE LINE

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 cen­tering. 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.

COMBINING ADDITIONAL IR RECEIVERS

TROUBLESHOOTING

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-modulat­ed 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 com­ponents.

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 emit­ter 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.

This method combines the modulated IR signal at the con­necting 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.
