MASTER
MONITORING THE SYSTEM
The PHONES/MONITOR section allows the engineer to
listen to L-R (aux 5-6) either PRE or POST the master
faders, or 2-TRACK return through up to two pairs of stereo
headphones or monitor speaker systems while displaying the
selected source on the L and R monitor meters. The peak
responding LED bargraph meters are positioned above each
group strip.
Pressing any AFL or PFL switch interrupts left and right of
the monitor with the selected signal in mono and displays
AFL (AFL active LED on) or PFL (PFL or AFL+PFL LED
on) on both meters.
Source selection follows this priority:
PFL overrides AFL overrides 2-TRACK overrides L-R PRE overrides L-R POST
2-TRACK RECORD AND REPLAY
2 pairs of phono connectors, SEND and RETURN, allow
convenient connection to a 2-track recorder such as cassette
or DAT. The send may also be used as an additional
unbalanced L-R output. These connections are set as stand-
ard for low level operation (-10dBV). For high level
recording the balanced L-R XLR outputs may be used.
MONO OUTPUT OPERATING MODE
The recessed MONITOR MODE switch determines the
function of the balanced mono output.
For F.O.H. applications (switch up) the main L and R
outputs are summed to drive a centre MONO FILL speaker
system. Alternatively this output may be used for mono
recording or to provide a mono broadcast feed.
For ON-STAGE operation (switch pressed) this output
becomes AFL interrupted by PFL to drive an engineers
WEDGE MONITOR system. The wedge mix is created by
pressing the required aux (group) AFL switch combination
to listen to the monitor send mix. Pressing any PFL switch
allows the engineer to check the channel signals, for example
while setting the gains or EQ.
On-stage monitor systems usually include a graphic equal-
iser on each monitor feed adjusted to tune out the resonances
which cause acoustic feedback. These equalisers should be
patched into the console group inserts so that their effect may
be monitored when AFL is pressed.
THE MAIN L-R OUTPUTS
The L and R output section is identical to the group section
with aux reverse switching which configures the main
outputs for aux 5, 6 when required. Note that the subgroups
always route to the L-R mix and are therefore present at the
aux 5, 6 outputs when reverse is selected. It is possible to set
up an additional stereo or two mono monitor sends from a
combination of monitors (aux) 1 to 4 when SUBGROUP is
selected. Alternatively the four return inputs provide a fully
independent stereo sub mixer when RETURN is selected.
