1 Reference Monitor Controllers Introduction
The Reference Monitor Controllers are a range
of 1U rack-mount audio production control
units, for providing source selection, volume,
DIM and CUT controls for external analogue
monitors, together with light controls for the Sonifex SignalLED range of
studio signs, or similar.
Each of the products has a light control section. This section has 3 buttons:
Transmit (TX), STANDBY and Rehearse (REH). The TX and REH buttons
control opto-isolated outputs on the rear panel remote connector, and
these provide a direct control interface to the Sonifex SignalLED illuminated
studio sign, allowing twin signs to be controlled individually.
The Standby button initiates a 2 minute countdown where the TX and REH
buttons and their associated remote outputs flash alternately. After the 2
minutes has elapsed, the TX output remains on.
The remote port also has open-collector tally outputs for Transmit (TX) and
Rehearse (REH), as well as remote input control for the audio controls DIM
and CUT, and the light controls TX, Standby and REH. There is also a +12VDC
source at 200mA maximum.
The TX, STANDBY and REH buttons can optionally be replaced if you want to
use different buttons for other applications.
