Bogen VAR1 Voice-Activated Relay

Voice Activated Relay. The VAR1 is a relay device that monitors audio activity over wide range of input voltages and operates two sets C-Form contacts in response to detected activity. can be used detect as low signals directly from microphone or high 70V speaker systems. low-level output audio, transformer-isolated input, also made available for use with other equipment. balanced, low-impedance pre-amp. ideally suited provide set contact closures paging ports lower cost telephone systems do not have AUX trigger An adjustable release delay (up 25 seconds) keeps system dropping out middle page.

• Monitors voltages
• Two (both N.O. N. C.) respond activity
• Four levels signals: microphone, 600-ohm line, 25V, systems
• Built-in noise, gain pre-amp
• Transformer-isolated, small signal level available
• Works self-amplified central-amplified systems
• Separate pre-amp control
• Adjustable delay: 0.25s 25s
• Trigger threshold adjustment
• Relay active indicator light
