6. OPERATION
The SIGNAL PRESENT LED’s give a continuous indication of the signal from each of the
eight connected amplifiers. Note that very low levels may not be detected.
To monitor a particular amplifier, SELECT the desired amplifier. The listening level may be
adjusted using the MONITOR SPEAKER VOLUME. The PROGRAM LEVEL meter gives accurate
indication of signal from the selected amplifier.
Setting the level:
The monitor speaker level has been designed to accept a wide range of program levels.
Distortion may occur in the MP8 if the speaker volume control is set too high while the
amplifier is producing a high output, as indicated by the program level meter. Check the
setting of the level control and reduce if necessary. If distortion is still present, then check
amplifier operation and affected speaker lines.
Switching the Monitored Zone:
It is possible to select 2 amplifiers at once and monitor them simultaneously, however, this
is not recommended. Fusible isolation protection exists to protect both the external
amplifiers and the MP8.
A NOTE ABOUT MONITORING:
It should be noted that adjusting the monitor speaker level control does not effect
the sound level in the selected zone and nor do the level indications indicate the SPL
of the speakers in any zone. The MP8 should be used to monitor an amplifiers output
signal quality and presence only and as such, it does not reflect the condition of the
actual sound output in any speaker zone.
