DIM Level Adjustment Potentiometer
The DIM level potentiometer sets the attenuation applied to audio output when the DIM
button is active. Turn the potentiometer clockwise to decrease the DIM attenuation level
and clockwise to increase it (altering the audio level by -2dB to -23dB).
Audio Inputs
The single stereo audio input is via two XLR-3 pin socket connectors with the following pin
assignments:
Pin 1: Ground
Pin 2: Phase
Pin 3: Non-phase
Audio Outputs
The single stereo audio output is via two XLR-3 pin plug connectors with the following pin
assignments:
Pin 1: Ground
Pin 2: Phase
Pin 3: Non-phase
Remote Port
The Reference Monitor Controller’s remote port has 2 optically isolated drivers for the
Transmit (TX) and Rehearse (REH) controls that provide a direct control interface to the
Sonifex SignalLED illuminated studio signs. To drive a SignalLED studio sign from these
drivers, the Emitter connection would typically be connected to 0V and the collector
connection would be connected to one of the active low signalling inputs.
The remote port also provides 2 open-collector tally outputs for Transmit and Rehearse,
and 5 active low inputs to activate the Transmit, Rehearse, Standby, CUT and DIM controls.
