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.
