EXTERNAL MUTE OPERATION
If the external mute mode is enabled the following happens when the n.c. link on the rear of the console goes open circuit:
The pre-insert signal from the mic on channel 1 is routed directly to the master outputs, bypassing all level controls and
eq controls. Its level is set only by the pre-set level control underneath the top fascia.
The channel 1 mic signal will be shown on the meters.
The channel 1 mic signal will be routed to the headphones.
All other music or mic signals to the master outputs will be cut.
The booth outputs will be cut.
All the Signal-Beat-Peak LEDS flash red.
The LED in the MIC switch on channel 1 will flash if mic is not selected.
