PFL/TB: Volume control for the built-in PFL/TB speaker.
EXT PFL: The EXT PFL input can be used as an external PFL input to the monitor-
ing unit. If pressed, the key is illuminated, the external signal is routed to
the PFL output, and the external PFL control output is active.
If PFL is active on any channel, the PFL signal is routed to the main
monitor speakers. If no PFL is selected, the monitoring signal is the stereo
CR signal as selected. The PFL>MON key is illuminated if active.
: Headphones volume control. The headphones socket (6.3 mm TRS jack) is
located below the hand rest on the left side of the console.
Three keys allow different monitoring modes:
PFL: PFL and TB signals are routed to the headphones.
The left-channel headphones signal is the mono PFL signal, while the
right-channel headphones signal is the mono CR signal as selected by the
monitoring source selector [1]. If no PFL is selected, the headphones sig-
nal is the stereo CR signal as selected.
MON: The headphones signal is the same stereo signal as selected by the moni-
toring source selector [1]. It is, however, not affected by the DIM and CUT
functions.
Selector for five talkback destinations:
Connection between the talkback microphone* in the control room and the
corresponding clean-feed (N–1) output; this allows talking e.g. to the con-
nected telephone hybrid(s) or communication lines.
Connection between the talkback microphone* in the control room and the
AUX 2 or AUX 1 outputs.
STUDIO: Connection between the talkback microphone* in the control room and the
studio speakers and headphones.
The built-in PFL/TB loudspeaker and/or the headphones are used for talk-
back listening in the control room.
* If a console is equipped with an external talkback microphone, this micro-
phone is used instead of the integrated talkback microphone.
Spare keys for future functions.
ON-AIR Is turned on by a control signal on the "SIGN." control connector on the
monitoring part of the connector panel.
CR-MIC Is on if at least one microphone in the control room is routed to the pro-
gram or to the record output (i.e. the corresponding output is selected, the
input channel is ON, the input channel fader and the master fader are
opened).
Is on if at least one microphone in the studio is routed to the program or to
the record output (i.e. the corresponding output is selected, the input chan-
nel is ON, the input channel fader and the master fader are opened).
