Russound A-C68 Installation Manual
System Installation Considerations
The A-C68 can be shelf or rack-mounted. Locate the A-C68 near the sources
for RCA connections and IR emitter placement. Also allow for any other
connections for Mute and Page In.
System keypads are located in various rooms and connect to the controller
with CAT-5 cable. Speakers in these rooms connect directly to the keypads with
standard speaker cable.
There are several factors to consider before installing the Russound A-C68
system:
What are the intended listening zones(rooms)?
What system options and accessories might be required for additional
features such as local sources?
From where in each zone will the user prefer to control the system? Where
will the keypads be located? Where will the speakers be located?
Connection Tips
It is recommended that the A-C68 and the source equipment be plugged into
a dedicated circuit with an isolated ground. A power line conditioner can reduce
interference problems caused by noise found in some electrical systems.
For all RJ45 connectors, use T568A wiring standard.
Disconnect all live power cords before making connections to the
controller.

Check for correct connections and polarity.
Keep all power cords away from all signal cables to prevent humming from
induced noise.
Choose reliable signal cables/patch cords.
Label all wires with room location at both ends of the wire.
Keypad Wiring
To determine the amount of CAT-5 wire required for the system installation,
first decide how many keypads will be used, then determine the distance
between each intended keypad location to the planned A-C68 location. The
maximum recommended wire run length from controller to keypad is 150 feet
for each A-K5L or A-K3 keypad (includes use of A-LC3).
Make sure that the entire wire path between keypads and A-C68 is clear and
not obstructed by a floor ceiling joist, or masonry wall which can’t be drilled
through. Confirm ahead of time that you can drill an outlet hole easily and in an
unobtrusive spot to connect wires with the A-C68.
Label wires with keypad and room location. This simplifies A-C68 hook-up
once the keypads and speakers are installed.
Speaker Wiring
Speakers in each system room connect to the keypad with standard 16-gauge
4-conductor stranded speaker cable. It can be run up to to 125 feet; 14-gauge
wire can be run up to 250 feet.
When running cable, avoid locations concealing pipes, heating ducts and AC
wiring in the general vicinity.
Avoid running wires close to house electrical wiring for any distance. If you
have to run them parallel, make sure to space the wires at least two feet from
the AC line.
