Control Room Monitor
The cue system features Autocue and a
separate “Assignable Output” that can be
setup as a cue output for an external amp
and speaker (or Record output for the Telco
system). Whenever a fader channel is placed
into cue, the monitor audio is dimmed by an
amount set in the PC setup utility, and the
cue audio is played over top. Autocue also
operates into the Headphones. If an external
cue amp and speaker are used then the
autocue feature can be defeated in the con-
sole setup.
Whenever a local microphone is turned
on, the console muting system is activated.
This results in the monitor and cue outputs
being muted to avoid feedback. A logic out-
put is also activated to drive an appropriate
On Air Warning light.
The timer features manual and automatic
control. When the Auto button is active on
the operator control panel, the timer is reset
to zero whenever certain console channels
are turned on. The channels that will reset
the timer are selected in the PC software
setup utility. The operator panel has switch-
es for manually starting, stopping, and reset-
ting the timer.
Operation of the control room monitor sys-
tem is displayed and explained below.
