If the monitoring source is AUDIT (audition bus), the monitor speakers are
either dimmed (DIM key illuminated), muted (CUT key illuminated), or
not affected at all, according to the configuration (see
chapter 11.2.2 for
details).
If talkback is active, the level of the monitor speakers is dimmed by 20 dB
and the DIM key is illuminated.
External CR DIM: Provided that the corresponding Customer Code has been activated, an
additional control input signal on the “SIGN.” connector allows to reduce
the level of the CR monitor speakers by 20 dB (refer to
chapters 11.2.11
and 14.11 for details).
The signal on the PFL bus is reproduced by the console’s built-in speaker.
The same speaker is used for talkback. The volume is adjusted with the
PFL/TB potentiometer.
For monitoring purposes, a headphones connector is provided on the left
side below the hand rest of the console. Three keys allow different moni-
toring modes, as described below:
Key Function Description
PFL
The headphones signal is the stereo PFL signal.
PFL is illuminated if selected.
PFL/CR monitor
The left headphones signal is the mono PFL
signal, while the right headphones signal is the
mono CR signal as selected by the monitor
source selector. If no PFL is selected, the head-
phones signal is the stereo CR signal as selected.
MON/PFL is illuminated if selected.
CR monitor
The headphones signal is the same stereo signals
as selected by the source selector for the monitor
speaker. MON is illuminated if selected.
The CUT and DIM keys have no effect on the headphones signal. The
headphones output is not muted if one of the control room microphones is
on. The incoming talkback signal from the studio is mixed to the head-
phones output. For improved intelligibility, the monitoring signal is at-
tenuated by 20 dB.
The PFL to MONITOR function feeds the PFL signal to the monitor loud-
speakers, if PFL is selected on any channel. The normal monitoring signal
is muted for as long as any PFL keys are active.
Key Function Description
PFL to MONI-
TOR
The PFL signal is routed to the monitor speakers
if PFL on any channel is active. If no PFL is se-
lected, the monitoring signal is the stereo CR
signal as selected. PFL > MON is illuminated if
active.
A volume control knob (PHONES ) adjusts the headphones listening
level.
