O1 PFL TRIM. Adjust this control to set the
listening level of the PFL selection. Provides a
range from -12dB attenuation to +6dB gain with
normal ‘0dB’ centre detented position. It does not
affect the PFL metering which always reflects the
true reading.
This lets you match the PFL listening level to your
normal AFL and main mix monitoring levels,
typically much quieter. It can prevent the sudden
rise in volume when you press a PFL switch.
O2 2TRK SOURCE. Press this switch to listen
to the 2-track input in the headphones, local, and
engineers wedge monitors. The signal is fed in
mono to the engineers wedge. This lets you check
the output of a stereo recorder. This selection
overrides any selected LR and C monitor source
until released. It is itself overridden by any P/AFL
selection. The 2TRK source is not sent to the
meters.
O3 LR SOURCE. Press this switch to listen to
the main post-fade LR output in stereo. It is
overridden by the 2TRK and P/AFL selections.
O4 C SOURCE. Press this switch to listen to the
main C (centre) output in mono. As with LR it is
overridden by the 2TRK and P/AFL selections.
Press LR and C together to monitor a 3 output LCR
system in stereo. This mixes the C signal equally
into L and R.
O5 MONO. Press this switch to listen to the
selected monitor source in mono. This only affects
the monitor outputs.
It is useful to check for mono signal compatibility. If
the signal drops in level or loses quality when
monoed then there may be a problem with phasing
between the left and right signals.
O6 LOCAL MONITOR LEVEL. This adjusts the
stereo local monitor output level.
O7 MUTE. Press this switch to mute the local
monitor output. This does not affect the
headphones. It allows headphones only monitoring,
useful in performance situations where the console
is operated within the audience area, or when you
want to prevent acoustic interference when
checking signals in the headphones.
O8 PHONES LEVEL. This adjusts the level of
the monitor signal in the stereo headphones.
WARNING: To prevent damage to
your hearing start with the headphones level set
to minimum. Avoid continued high listening
levels in the headphones or any other earpiece.
P1 ADD MODE. This switch determines how the
P/AFL system works. It selects whether pressing
one or more input PAFL switches cancels or adds
to the previous selection, the same for the output
AFL switches. It does not affect the how the PAFL
and AFL switches interact.
Auto-cancel. In its up position auto-cancel mode
is selected. Pressing a PAFL automatically turns off
any previous PAFL selection, and pressing an AFL
turns off any previously AFL selection. This lets you
quickly check the channels one at a time without
having to turn each selection off first.
Add mode. Press this switch to select add mode.
Pressing a PAFL adds to any currently active PAFL
selection, and pressing an AFL adds to any
currently active AFL selection. This lets you check
combinations of signals in the monitor.
PAFL / AFL interaction. Pressing any PAFL while
AFL is active automatically overrides the AFL
selection by turning it off. Releasing PAFL restores
the AFL selection. However, pressing any AFL
while PAFL is active cancels the PAFL selection.
Releasing AFL does not restore the PAFL selection.
This logic suits live sound mixing where you would
monitor an output mix using AFL and interrupt it to
quickly check the input sources using PAFL.
P2 INPUT PAFL. In its up position pressing an
input channel PAFL switch selects PFL. In its down
position stereo in-place AFL is selected. It does not
affect the output AFL switching.
Input PFL (pre-fade listen). The input channel
pre-fade signal is monitored in mono.
Input AFL (after-fade listen). The input channel
post-fade, post-pan/blend signal is monitored in
stereo. It follows the setting of the pan and blend
controls with C mixed into L and R. This lets you
check the level and image of the signal in the mix.
Output AFL. The output channel post-fade signal
is monitored in mono or in stereo pairs.
P3 CLEAR ALL. Press this switch to turn off all
currently selected PAFL and AFL switches. Its LED
lights to show that one or more switches are active
and can be cleared. Note that this switch also
provides the clear/toggle function in SIP mode.
