Bogen VAR1 Voice Activated Relay Monitors audio activity over a wide range of input voltages. Two sets of C-form (both N.O and N.C) relay contacts respond to audio activity. Four levels of signals: microphone, 600-ohm line, 25V, and 70V speaker systems. Built-in balanced, low noise, high gain microphone pre-am. Transformer-isolated, 600-ohm small signal level output of detected audio available. Works with self-amplified or central-amplified paging systems. Separate microphone pre-amp gain control. Adjustable release delay: 0.25s to 25s. Trigger threshold adjustment. Relay active indicator light. Dimensions: 3″ H x 8.5″ L x 7.25″ W. Color: Black. Country of Origin: Korea.
