Bogen VAR1
Bogen VAR1 Voice Activated Relay
Mic level, 600ohm line level, 25V and 70V distributed speaker level. A low level, transformer isolated, 600ohm output is also made available for use with other equipment, allowing this to be used as a balanced, low impedance microphone preamp.
Bogen’s DC Power Supplies are designed to supply power to battery-operated, other low-voltage DC equipment, or 24V DC
equipment from a 120V AC source. They are rugged, versatile, and dependable, making them suitable for many types of
telephone paging equipment, amplified speakers and horns, tone generators, and intercom systems. 12V, 24V, and 48V models
available. PRSLSI additionally provides talk battery for loop start trunks and a buffered audio output to drive up to 25 selfamplified speaker inputs.

The VAR1 can be used to detect voltages as low as signals directly from a microphone or as high as signals from 70V speaker systems. 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.
