7.5 Connecting the IR Link
• When two CA6.4 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", mono, phone plug, male-to-male cable connected from the IR Link on the first CA6.4 Controller to the IR Link on the sec-
ond CA6.4. When connected, you may connect your IR emitters to either unit's IR Remote Output jacks.
7.6 Keypad Connections
• Each keypad connection on the back panel 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. 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. At this point it is not important
what color wires connect where, however, take note of the color of each wire and number indicated on the connector when con-
nected to the back panel.
• Write down the room name to the zone number below. Note: the keypad and the speakers in each room must be hooked to the
same zone number. See List 3.
List 4 – Room names should be written below.
Zone 1 ______________________ Zone 2 ______________________ Zone 3 ______________________
Zone 4 ______________________ Zone 5 ______________________ Zone 6 ______________________
List 5 – Wire color should be written below.

8. Standard Keypad Installation
The CA6.4 Central Controller Amplifier is offered with standard keypads and
LCD keypads. If you are installing a unit with LCD keypads skip to step 9.
8.1 Installing the CA KP Keypads
• The best performance is achieved with the keypad away from any direct sunlight. Also consider the 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) and cut
in the boxes using a key-hole saw or sheetrock knife/hand saw.
• Route the wire to the junction box from the CA6.4 location.
• Strip the insulation back 1/8" from each twisted wire. Connect each
wire to the correct position 1 thru 8. Refer to List 5.
• If you feel uncomfortable cutting into your walls and running wire through
the walls, seek help from a professional installer or an electrician.
• Mount the keypad in the junction box and attach the Decora plate.
• The CA KP keypad has source labels for your convenience. Place the label
on the keypad keeping the input number in sequence with the source
selected.
• Repeat the above steps until all keypads are installed.
NOTE: Preset volume and balance level adjustments
can be made via the volume (VOL) and balance (BAL)
potentiometers mounted on the keypad's circuit board.
