Master output
The master output is on a pair of balanced XLR connectors, there is a 12 LED stereo
meter and volume control labelled MASTER.
There is a voiceover facility in the master section which allows a signal on the
microphone buss to automatically reduce the music level by an adjustable amount.
The voiceover is selected on a switch, the microphone level that triggers it is set by
the sensitivity pot and the amount the music is reduced is set by the attenuation pot.
The microphone buss consists of the console microphone signal plus any channel
microphone inputs that are assigned to the microphone buss.
There is also an insert in the master output stage on a pair of ¼” jack sockets, the
insert is enabled by a switch marked INSERT.
Note the send path is always active, the insert switch bringing in the return path.
Booth output
The booth output is on a pair of balanced XLR connectors; there is a 12 LED stereo
meter and volume control labelled BOOTH.
There is a MONO select switch that sums the booth left and right to mono. There is a
PAN control that operates in stereo mode, with MONO selected the PAN pot has no
effect.
FX LOOP
Each channel has a FX switch, when one channel is selected that channel is sent to
the FX loop and the return from the FX loop routed back to that channel. (Selecting
FX on more than one channel disables the facility).
The FX loop has variable frequency high and low pass filters (enabled by a switch)
and a compressor (enabled by a switch). The compressor has preset threshold and
ratio that is preset by pots through the back panel.
The FX loop goes to FX send return jacks on the back panel, the jacks are switching
so if no FX unit is connected the send signal is automatically returned.
The FX return goes to a wet/dry pot (along with a copy of the send signal), the
wet/dry pot setting determines how much original signal and how much FX return is
sent back to the channel with FX selected. In the wet position the signal is the FX
return signal.
