X-microphones will be panned hard left, and Y-microphones will be panned hard right.
Spot microphones will be panned to their correct position in the final L-R image.
Earlier we mentioned conflicting monitor requirements; a problem arises when
monitoring an S-channel after its S-switch has been selected. In this case +S would
appear on MON left and -S on MON right - not very useful! To overcome this
difficulty, swing the monitor BAL control (11) hard left and select MONO (14), thus
isolating the in-phase signal from the S-channel. Alternatively, and if the engineer
has requested a restricted swing on the BAL control (11), selecting either of the
MTX switches and MONO (14) will achieve the same result.
When mixing in the M-S domain, M-channels will be panned hard left and
S-channels will be panned hard right. Spot microphones will be panned left to mix
with M-channels only. Any X-microphone will be panned centre and any Y-
microphone will be panned centre and have its S-switch (15) selected - thus
converting the X-Y microphone to the M-S domain.
MON on an M-channel will audition the M-signal on monitor 1 left output, and MON on
an S-channel will audition the S-signal on monitor 1 right output. By selecting
MONO (14) on the monitor module, each of these signals will appear on monitor 1 left
and right outputs. If the M- and S-channels are selected simultaneously to MON, the
resultant (M-S) signal is incomprehensible, but can be converted to the L-R
domain by selecting MTX 2 (13) on the monitor module. By using the monitor
BAL control (11), this L-R signal can now have its width changed and potential
realised without changing channel settings.
An M-S main mix may be matrixed to the L-R domain for the final output from the
mixer by MTX (6) on the output module (before any final limiting).
When mixing in the L-R domain without M-S microphones, X-Y (A-B) microphones will
be panned hard left (X) and hard right (Y), and any spot microphone will be panned to
its correct position in the final L-R image.
CH (1) on the monitor module and MON selected on both channels of an X-Y pair
auditions each stereo microphone. MON on a spot microphone is solo-in-place
usage of the monitor system.
When monitoring an X-Y microphone, MTX 1/BAL/MTX 2 will reveal the potential of
angular changes to the microphone - or possibly a change of position - without having
to gain access to the microphone.
(All auxiliary sends will be in the L-R domain.)
