MONITOR MODULE CONNECTION
Ten 6-pin connectors, using the AirWave Digital stan-
dard audio pin-out sequence, are on this module. The
3-pin
Cue Spkr output is pre-wired to the Cue Speaker.
Two direct (fixed level, non-muting) outputs are available:
C/R Direct follows the control room monitor selector and
Studio Direct follows the studio selector. These can drive
guest headphone amplifiers.
The
Cntrl Rm Main output feeds the amplifier for the
control room monitor speakers. This output is controlled
by the control room monitor level control and the control
room mute logic. The
Cntrl Rm H/P output may be used
to drive an outboard headphone amplifier. This output is
controlled by the control room headphone level control.
The
Studio Main output feeds the amplifier for the stu-
dio monitor speakers. The
Studio H/P output may be used
to drive an outboard headphone amplifier having level
control. The Studio Main output is level controlled by the
studio monitor control and muted by the studio mute logic
coming from the Input modules.

C/R & Studio Warning connector
The 8-pin

The Pgm-1 input is connected to the Output module’s
Pgm-1 Monitor output using the supplied jumper cable.
The other three External inputs can come from any +4
dBu balanced sources.
