Automatic Left/Right Line Level Switch
Automatic switch is perfect when two stereo line level sources need to be fed to a single amplifier input. Inputs are identified as A and B, with INPUT-A as the default. When an audio signal is detected at INPUT-B, the switch automatically switches to that input. When INPUT-B is silenced, the output automatically reverts back to INPUT-A. The delay time for reverting back to INPUT-A is adjustable from 0.5 seconds to two minutes.

Product Description

Popular applications include commercial or home audio systems with too few line inputs, or situations where input selection needs to be made on equipment that is not in a convenient location.

SPDT relay outputs are provided that mimic the A/B input selection, allowing this device to trigger external components. It may even be desirable to use this switch simply as a sound activated SPDT relay.
