Product Overview


  • Two sets of C-Form (both N.O. and N.C.) relay contacts respond to audio activity

  • 4 levels of input signals: microphone, 600-ohm line, 25V, and 70V speaker systems

  • Adjustable release delay – 0.25s to 25s 

  • Separate microphone pre-amp gain control

  • Relay active indicator light

  • Built-in balanced, low noise, high gain microphone pre-amp

  • A transformer-isolated, 600-ohm small signal level output of the detected audio available

  • Trigger threshold adjustment 

Details

The VAR1 Voice-Activated Relay for Paging System by Bogen is designed to detect voltages signals directly from a microphone or as high as 70V speaker systems, with multiple applications such as muting a sound system in response to a page announcement, activation of accesories or activation of a paging zone

A low-level output of the detected audio, transformer-isolated from the input, is also made available for use with other equipment. The VAR1 can also be used as a balanced, low-impedance microphone pre-amp.

The VAR1 is ideally suited to provide a set of contact closures for paging ports of lower cost telephone systems that do not have a set of AUX contacts to trigger paging equipment. An adjustable release delay (up to 25 seconds) keeps the paging system from dropping out in the middle of a page.
