96. II (Group/Matrix/Aux meters and indicators)
On 24 and 32 channel mainframes, these four
meters monitor the correspondingly numbered
busses, as described above in item [95].
In 40 or 48 channel mainframes, these eight
meters display the eight group outputs or the
eight matrix outputs (redundant with the first
two selections for the I set of meters [95]), or the
aux outputs. This AUX selection differs from the
AUX choice in the I set of meters [95] in that it
displays the levels for aux stereo 1 and 2 outputs
(L&R), the monitor A output (L&R), the TB
output, and the OSC output.
The GRP, MTRX or AUX indicator above the
meters is illuminated to designate the output
levels on display.
97. ST L, ST R (Stereo output meters)
These two jumbo meters monitor the left and
right sides of the stereo master output. These are
dedicated meters that always monitor the same
signals, regardless of any meter select, cue or solo
mode switching.
98. AUX ST 1L, MON A L
AUX ST 1R, MON A R (meters and indicator)
These two meters normally monitor the corre-
spondingly labeled auxiliary 1 stereo (left and
right sides).
When the an input or bus CUE switch is engaged,
the meters display the Monitor A output signal
(which is the cue signal), and the MON indicator
above the meters turns on.
99. AUX ST 2 L, TB
AUX ST 2 R/OSC (meters and indicator)
These two meters normally monitor the corre-
spondingly labeled auxiliary 2 stereo (left and
right sides).
When the the talkback switch is engaged, the
AUX ST 2L meter instead displays the Talkback
output signal and the TB OSC indicator above
the meters turns on. When the oscillator output
is switched on, the AUX ST 2R meter instead
displays that oscillator signal, and again the TB
OSC indicator above the meters turns on.
100. MON meter function switch
If you wish to force the accompanying pair of
meters to indicate the monitor output levels when
no cue switch is engaged, press this switch. The
accompanying pair of meters will now display the
MON A left and right levels instead of the AUX
ST 1 levels.
