S-switch (23) creates a matrix amplifier across an adjacent pair of input modules.
Refer to M-S NOTES.
The panoramic potentiometer (11) routes the signal proportionately
between A and/or C outputs (L) and B and/or D outputs (R). Routeing switches (12)
are independent of each other and also act as channel mutes.
The monitor 1 path is the true output from the module (independent of any other
routeing) and is derived from the output of the panpot - and S-switch (23) if selected.
MON (24) routes the channel signal to the L&R monitor 1 modules and is auditioned
when CH (1) is selected on BOTH monitor modules. This monitor 1 output also
automatically appears on monitor 2 (headphones) output. MON can also be used as
an AFL (after-fader listen) function, ie to monitor the mono output of the module. In
this case, select MON (24), and CH (1) on EITHER monitor module.
Non-destructive SIP (solo-in-place) usage of MON is outlined in the MONITOR
MODULES section.
If the post-fader channel output (clean feed) option has been included, the signal will
appear on a stereo jack in the centre of (XLR) CONN 2. Alternatively, it may be
chosen to replace LINE input on Conn 2. Situated on the module’s main PCB
is (DIL) SW 16 to select the signal pre or post fader. (DIL) SW 17 allows the
module to drive unbalanced loads - without a reduction in signal level. Refer to
TECHNICAL LIBRARY.
PFL (13) routes the signal at the fader input to monitor 2, ie the headphones-output
jack and balanced L&R outputs on XLRs. PFL overrides any other signal appearing
on monitor 2.
The Penny & Giles fader (15) is calibrated 10dB down from its fully open position,
allowing the operator to work with 10dB of gain in reserve. Faders on adjacent
modules can be coupled for stereo operation by the use of standard ganging clips.
