Master Module
Output Phase
10
The PHASE switch, which has an integral red LED, reverses the phase of both
left and right outputs. The outputs themselves are electronically balanced at +4dBu,
on male XLRs on the rearcon.
External Input
11
A stereo external input, from XLRs on the lower rearcon, may be added to the
mix buses. The inputs are balanced with a sensitivity of +4dBu. The EXT IN
control adjusts the level of the external signals, with 10dB of gain fully clockwise.
12
The MNO (mono) switch sums the external signal to mono before it is fed to
the stereo mix.
13
The latching ON switch activates the external input. An integral green LED
indicates when it is on.
14
The LSTN (listen) provides a mono pre-fade, pre-ON solo to the 'phones or
wedge output. LISTEN is not affected by the AUTO CANCEL or SOLO CLEAR
functions, and overrides any output AFLs if INPUT PRIORITY is active.
Using the Solo System
A solo system of pre-fade listen (inputs) and post-fade listen (outputs) feeds the
operator's wedge/'phones outputs.
Normally, all active AFL, PFL and LISTEN signals are summed together and fed
to the wedge or phones outputs.
When INPUT PRIORITY is selected by the ENBL switch, which has an integral
red LED, an active PFL or LISTEN will replace any AFL signals, which will be
audible only when all the PFL/LISTENs are released.
15
The PFL TRIM control gives +/-10dB of level trim for PFL/LISTEN signals.
The SOLO CLEAR button lights when any AFL, PFL or LISTEN is active. Pressing
it will clear a PFL or AFL, but not a LISTEN.
When AUTO CANCEL is activated by the ENBL button, which has an integral red
LED, any AFL or PFL will cancel any currently active solo, so only one AFL or
PFL can be active at once.
LISTEN buttons are not affected.
