It features versatile multi-input audio detection, adjustable VOX sensitivity and release delay, a built-in high-gain microphone pre-amp, and robust relay contacts for reliable switching. Compatible with various paging setups, it ensures seamless, dropout-free activation of external equipment, making it an essential tool for modern audio management. ## Description The VAR1 intelligently detects audio activity from various inputs—including microphones, 600-ohm lines, or 25V/70V speaker lines—and activates its relay contacts to trigger external equipment or override existing audio channels.The adjustable VOX sensitivity allows installers to set the exact audio level required to trigger the relay, while the adjustable release delay ensures the channel remains active during natural pauses in speech, preventing annoying paging dropouts. It also includes a microphone pre-amp and a transformer-isolated audio output. The unit requires an external 12V to 24V DC power supply (not included)Key Features:Versatile audio detectionAdjustable VOX sensitivity to set the exact trigger threshold and an adjustable release delay Includes a built-in balanced, low-noise, high-gain microphone pre-amp with separate gain control, plus a transformer-isolated 600-ohm audio outputWorks seamlessly with both self-amplified and central-amplified paging systemsProvides both Normally Open (N.O.) and Normally Closed (N.C.) operationRated at 2A at 30V DC or 0.5A at 120V AC.

Review: VOX For Ham Radio - I wanted a single VOX to control all of my transmitters in my ham radio setup and this looked a good candidate. I already have all of my microphones going through a single mixer so it was a no-brainer to wire a spare line level output to the input of the VAR-1. My station has a master 12 volt power supply that I used to power VAR-1 once I figured out that the power plug needed to have the negative connected to the center pin (not standard). That requirement is printed right on the unit so I can't blame Bogen. I run it with the input sensitivity set to max and the delay set to min which seems to be just about right for my application. Review: Exactly what I was needing for a VOX/Relay Project ...... :-) - Did exactly what I needed for a Communication Center ~ Audio Project that was expected of me; And, I had to search around the Country for something that would give me ALL the VOX/Relay sensitivity needed to switch the Relays' Off &/or On - on demand !! PERFECT !! ...... ## Features - Versatile audio detection: The DPDT relay activates upon detecting audio activity from multiple input sources, including microphone, 600-ohm line, 25V, and 70V inputs, making it ideal for priority paging and emergency announcements - Precision control: Features adjustable VOX sensitivity (20 mV to 150 mVrms) to set the exact trigger threshold and an adjustable release delay (0.25 to 25 seconds) to prevent audio dropouts during pauses in paging - Audio interface: Includes a built-in balanced, low-noise, high-gain microphone pre-amp with separate gain control, plus a transformer-isolated 600-ohm audio output for integrating additional equipment - System compatibility: Designed to work seamlessly with both self-amplified and central-amplified paging systems, featuring an input source selector switch for Mic or Line level signals and a visual LED status indicator - Robust switching capability: Provides two sets of C-form relay contacts offering both Normally Open (N.O.) and Normally Closed (N.C.) operation, rated at 2A at 30V DC or 0.5A at 120V AC.
