Russound AB-3 Instruction Manual Download Page 1

The Russound Model AB-3 Automatic Speaker selector is

designed to provide automatic switching of two amplified audio
sources to a single pair of speakers. The AB-3 provides automatic
switching from the main audio system (

AMP A)

to a remote audio

source (

AMP B)

. For example, connect the speaker output of your

TV and your stereo receiver to the selector. 

AMP B

has priority

when both audio signals are present. If you are listening to the
stereo (

AMP A)

and turn on the television (

AMP B)

, the 

AMP B

audio will override the 

AMP A

audio.

It is recommended that the AB-3 be located near the “priority”

source, minimizing the length of cable. This will help eliminate the
possibility of picking up extraneous noise.

The AB-3 includes a sensitivity trigger adjustment to allow

switching between the sources (signals) at a desired volume level. It
also includes a delay adjustment to prevent source switching during
the absence of a signal.
