LOCAL MONITOR LEVEL
stereo local monitor output jacks. This does not affect the level in the
headphones.
PFL ENABLE
With this underpanel switch in its down position PFL
automatically overrides the selected source in the local monitor output.
The switch is tamperproof to prevent accidental operation. In the up
position PFL affects the headphones but not the local monitor. This
lets the engineer or presenter cue channels using PFL in the
headphones only. This is typical in broadcast or club monitoring. In
broadcast, the local monitor could also be used to feed guest speakers
or headphones.
Here, PFL should be disabled so that only the
presenter is able to cue the channels. In club mixing the local monitor
may feed a booth speaker system. The DJ may prefer to cue using
headphones only.
DIM
Press this switch to mute the local monitor output. An internal
option reconfigures this to attenuate the signal by 20dB rather than
mute it if required, for example to keep some program audible at all
times. The red LED lights when the monitor is dimmed. This function
can be remote controlled by options wired internally. For example, in a
broadcast application a switched fader could be fitted and wired to
mute the studio monitor speakers when the presenter mic is live.
Refer this work to competent service or installation personnel. Further
information is available in the applications section of this User Guide.
SPLIT PFL
Press this switch to change the way PFL operates.
Normally, pressing a channel PFL switch overrides both left and right
monitor program signals with the mono PFL signal. With the switch
pressed, PFL overrides just the left channel. The left program signal
sums with the right so that the program remains in the right channel
but in mono. The left monitor meter displays the PFL signal, right
displays program. This is important in applications such as broadcast
or club mixing where the main program should remain audible while
cueing other channels ready to bring them into the mix. It is most
effective when using headphones.
MONO
Sums the left and right monitor signals together so that the
selected stereo source can be checked in mono. Use this to check for
mono compatibility and phase problems, especially important in
broadcast and recording applications. A drop in level or loss of low
frequencies when pressed indicates reversed phase between the left
and right signals.
