Two Channel Stereo Contractor Amplifier
Highly versatile amplifier is designed to power additional zones in an existing whole house audio system, or multiple zones, with external impedance matching. Because it also includes speaker level inputs, and auto switching, it can also be used to place a local source on a pair of speakers connected to a separate whole–house system.

Four trigger modes:

  • Audio sensing from a line or speaker level source
  • Video sensing at composite video loop-through jack
  • 12V AC/DC trigger input
  • Current sensing AC accessory outlet
