Brief Product Description:

Bogen Voice Activated Relay



The VAR-1 is a relay device that monitors audio activity over a wide range of input voltages and operates two sets of C-Form relay contacts in response to detected activity. The VAR-1 can be used to detect voltages as low as signals directly from a microphone or as high as signals from 70 V speaker systems. A low-level output of the detected audio, transformer-isolated from the input, is also made available for use with other equipment. Also can be used as a balanced low-impedance mic pre-amp.


  • Two sets of C-Form (both N.O. and N.C.) relay contacts respond to audio activity
  • Four levels of input signals: microphone, 600-ohms line, 25 V and 70 V speaker systems
  • Built-in balanced, low-noise, high-gain microphone pre-amp
