the signal level is approaching a clipping (distorted) level. The
next ten LEDs are yellow, indicating a normal level range, and the
remaining LEDs are green. The left member of the pair indicates
the level of the signal’s left channel, while the right member of the
pair indicates the level of the signal’s right channel.
The first VU METER PAIR shows the level of the PGM
output, while the second VU METER PAIR (the SWITCHED
METER PAIR) shows the level of the signal that is selected for it.
The SWITCHED METER PAIR can meter any signal appear-
ing at a console input connector, in which case the input’s left
signal appears on the left meter and the input’s right signal appears
on the right meter.
The SWITCHED METER PAIR can meter PGM, AUD, or the
combination of MONO1 and MONO2, with MONO1 appearing
on the left meter and MONO2 on the right meter.
If any channel is placed in cue, or if the TALKBACK button
is being held down, the SWITCHED METER PAIR will auto-
matically switch to meter CUE on the left meter and the console’s
talkback bus on the right meter. The SWITCHED METER
display (see below) switches to show “Q/TB”.
The SWITCHED METER PAIR can meter the caller feed
mix-minus buses (CF1 on the left meter and CF2 on the right
meter), or the general purpose mix-minus buses (MXM1 on the
left meter and MXM2 on the right meter).
METER SELECT BUTTON. - selects the source for the
switched meter pair.
METER DISPLAY - four character display shows the source
that has been selected for metering by the SWITCHED METER
PAIR.
Tallys
The console has two tally outputs. The first tally output is used
to drive user-provided external circuitry that will in turn operate
the control room on air indicator, and is called the ON AIR
TALLY. It is automatically activated whenever the control room
mute is activated. Thus, turning on any module that activates the
control room mute also turns on the on the on air tally. The second
tally is independent of muting, and can be used as a studio on air
tally, as a skimmer control, or for any other application requiring
a logic signal that depends on the ON status of one or more inputs.
Ask the technical person in charge of the console if TALLY 2
is used, and if so, what it is set up to do.
