15 MASTER VOLUME knob
By turning this knob one adjusts the volume of the
sum of all intercom signals as heard in the
loudspeaker and/or headset. This knob may also
adjust the master volume control for both the
intercom and the PGM (Program Audio) signals,
depending on the position of jumpers #44.
16 PGM VOLUME
By turning this knob one adjusts the listen volume
of the PGM input. The signal of the PGM input can
only be heard on the speaker and/or headset of
the PS 6379 Mk2 and does not appear on the
intercom lines.
If a TALK button is pushed and the speaker is On,
the speaker is automatically attenuated. This
diminishes the effect that the PGM signal goes
from the speaker into the microphone).
The position of jumpers #44 determine whether
the program audio listen level is also controlled by
the Master Volume knob (#15).
17 STAGE ANNOUNCE button
By pushing this button the microphone signal is
directly routed to the line level output at the rear
panel. The microphone signal (the 'Announce') is
not sent to the intercom channels. Whilst the
Stage Announce button is kept pushed, the
channel TALK buttons are disabled (the built-in
LEDs extinguish if they were lit before) and the
speaker is automatically switched off. To achieve
that the speaker is not automatically being
switched off, the position of a certain DIP switch
has to be changed. See section 11.0 DIP switch
D).
