REAR PANEL DESCRIPTION
1
BALANCED MAIN OUTPUT connectors:
Provide a fully balanced Main Output signal—pin 2 is (
+
), pin 3 is (
–
) and pin 1 is
signal ground. Pin 3 must never be grounded for unbalanced operation. Use only pin 2 as hot and pin 1 as return for any unbalanced
operation
.
2
UNBALANCED MAIN OUTPUT connectors:
Provide Main Output signals on ¼" TS (tip-sleeve) unbalanced connections.
3
BOOTH OUTPUT connectors:
The Left Output only supplies a mono Booth Monitor Output; connecting to both Left and
Right provides a stereo Output.
4
ZONE OUTPUT connectors:
The Left Output only supplies a mono Zone Output, connecting to both Left and Right provides
a stereo Output. The Zone Outputs are located Post-EQ, which includes the Microphone Output. An internal jumper block pro-
grams the Zone to Pre-EQ (and no mic) if required. (See Service Information on page Manual-9.)
5
MAXIMUM OUTPUT GAIN REDUCTION control:
Decreases the maximum Level of the balanced and unbalanced MAIN
OUTPUTS of the MP 24z as it is rotated counter-clockwise.
6
METER SENSITIVITY ADJUST:
Clockwise rotation decreases the full-scale sensitivity of the PEAK PROGRAM METER, as
indicated by the full-scale voltage calibrations around the control.
7
SYSTEM MONO/STEREO switch:
Engaging this pushbutton converts all Outputs (except tapes and loops) to MONO, regard-
less of the nature of the Input signals.
8
EQ RANGE switch:
In the out position, the maximum boost/cut available from the Program Equalizer is ±8 dB. In the switch’s
in position, this range is reduced to ±4 dB.
9
LIGHT CONTROL OUTPUT jack:
Provides a transformer-coupled mono program signal for use by a lighting controller’s trig-
ger input. This is a balanced ¼" output—the tip is positive, the ring is negative and the sleeve is floating.
0
LIGHT OUTPUT LEVEL attenuator:
Counter-clockwise rotation reduces the Output Level at the LIGHT CONTROL OUT-
PUT jack.
