Automatic Speaker Selector

The Atlas AA-PPRC controller is a two input by single output switch that provides automatic selection of a pair of speakers between two stereo amplified sources. It is perfect when a single pair of installed speakers is connected to a distributed audio system, but must also be used with a local source.
