Installation Manual
A-K4 Overview
The Russound A-K4 is an in-wall amplified keypad used
with A-BUS hubs and controllers in a distributed audio
system. It can be used with both single and multisource
A-BUS hubs/controllers. The A-K4 provides source selec-
tion and control with backlit push buttons, plus an IR
window to receive remote control signals.
The volume up/down buttons control the speakers in
the room that are connected to the A-K4. Typical installa-
tions place one A-K4 in each room of the A-BUS system.
The Line Out connection on the A-K4 can be used to
feed a separate powered subwoofer or to connect an
external amplifier for more power to a larger listening area.
