Dim Switch
The Dim function applies an adjustable gain reduction to the
Control Room outputs. This function affects all three output
destinations. The Dim switch toggles the dim function on and
off, and lights to indicate that it is active.
The amount of gain reduction is set with the Dim Level con-
trol, located at the top right of the Control Room Output sec-
tion.
Mute Switch
The Mute switch toggles the mute state for all Control Room
outputs. Mute operates globally on all three output destina-
tions. The Mute switch lights to indicate that it is active.
If the Mute switch on the XMON interface front panel is acti-
vated, the Mute switch on D-Control must be used to unmute
the monitor system. (Outputs cannot be unmuted from
XMON front panel.)
