The VAR1 Voice-Activated Relay shall be a DPDT
relay device. It shall be activated when an audio
signal is detected at the microphone pre-amp or at
70V, 25V, or 600-ohm line level inputs. A slide
switch shall be provided to allow selection of pre-
amp or the line inputs.
A VOX detect circuit shall be provided and shall
include sensitivity and delay controls. The audio
output shall be an isolated 600-ohm transformer.
Line impedance shall be 600 ohms, with a fre-
quency response of 100 Hz to 10 kHz. Sensitivity
and delay shall be controlled via recessed poten-
tiometers. Time delay range shall be adjustable
from approximately 0.25 to 25 seconds.
MIC Pre-amp shall provide 62 dB gain, with volume
control via a recessed potentiometer. The frequen-
cy response of the MIC pre-amp shall be 200 Hz to
10 kHz. Output signal-to-noise ratio shall be 55 dB
.
The VAR1 shall operate from a 12V to 24V DC
power source (sold separately). Dimensions shall
be 5-3/8" W × 3-7/8" H × 1-3/8" D. Weight of the
unit shall be 1 lb.
