Functional Description

Solo System

3
A solo system of pre-fade (inputs) and post-fade (outputs) feeds the monitor
5
and phones outputs. Normally, all active AFL and PFL signals are summed together
and fed to the monitor and phones outputs. This overrides the stereo mix or 2-track
signal which is normally fed to the monitor/phones output. The PFL/AFL TRIM
control gives +/-10dB of level trim for PFL/AFL signals. The SOLO CLEAR
button lights when any PFL, or AFL is active -pressing it will clear all PFLs or
AFLs. When AUTO CANCEL is activated by the ENBL button, any AFL or PFL
will cancel any other currently active solo, so only one AFL or PFL can be active
at once.
The SIP button disables the automatic switching of the monitor/phones outputs to
the PFL/AFL signal, and causes a solo mute bus to be activated when any mono or
stereo input or stereo return has its SOLO button pressed. The solo mute bus then
7
mutes all other channels except those which have either been jumper-programmed
to be 'SAFE', or have their own SOLO buttons pressed. The Group and Aux output
AFLs should not trigger the solo in place system, but should continue to be audible
on the monitor/phones outputs, even if SIP mode is selected.
The current solo signal is metered by the mono bargraph meter.

Monitor and Headphones Outputs

4
The Monitor Outputs and Headphones output share a common signal source
and are controlled by the MONITOR/PHONES LEVEL control . The monitor
outputs are via Left and Right 1/4" jacks on the rear panel with ground compensated
output. The PHONES output socket is a stereo 1/4" jack on the master module front
panel.
2
The signal source for these outputs is selected using the 2TRK and MONO buttons.
If neither are pressed, the post-fade stereo mix signal is fed to the monitor outputs.
If 2TRK is pressed, the post-fade signal from the 2-Track return section is fed to
the monitor outputs. Any PFL/AFL operation will override the mix or 2-track signal.
If MONO is pressed, the post-fade signal from the Mono Output is fed to the
3
monitor outputs.

Metering
5
Two 20-segment LED bargraph meters at the top of the module read the
post-fade stereo mix or 2-track return levels. A third 20-segment meter reads the
post-fade mono level. If a PFL/AFL is operated, the mono meter switches to display
the PFL/AFL level (pre the solo trim control). The meters normally have a peak-type
4
response, but internal jumpers allow this to be changed to average.
A remote meter connector is fitted to allow a parallel feed of the L/R/mono meter
signals to be connected to an optional LED or VU meterbridge.
