Australian Monitor
The Australian Monitor Installation Series MP8 is a 2 RU monitoring panel that allows you to monitor any of up to 8, constant voltage or low impedance speaker lines. This can be done via the on-board 2.5" monitor speaker or via the 8 segment VU meter. The MP8 also provides signal present LED’s for each amplifier as well as LED’s to indicate which amplifier is currently selected for monitoring. The MP8 operates from either an AC/DC 12V-24V plug pack or via 24 VDC & boasts ample label space.
We thank you for choosing Australian Monitor Installation Series &, as with all our products, the MP8 contains many clever features & is contractor friendly.

¬ Monitor Speaker:
A 2.5” speaker is located behind a cloth grille. No cleaning is required.
Monitor Speaker Volume Conrol:
This knob controls the volume level of the monitor speaker.
NOTE: The Speaker Volume Control does not affect the level of the VU indicator
nor does it affect the amplifiers or speaker lines that are connected to the MP8.
® VU meter:
This meter indicates the output level of the currently selected amplifier. The 0dB level is referenced to 100V. This is an RMS meter, not a peak meter.
¯ Selector Switches:
These switches select which amplifier is connected to the monitor and meter circuits. The switches are mechanical interlocking push buttons, meaning that when one button is pushed, the previously selected switch is mechanically deselected.
° Select Indicator:
This LED indicator will illuminate to show which amplifier is selected for monitoring.
± Signal Present:
This LED will light dimly when the signal from the corresponding amplifier reaches approximately -24dB (6.3Vac) indicating signal is present and will get progressively brighter with increased signal level.
NOTE: Signal present indication is irrespective of which amplifier is selected. This
indicator is a passive circuit across the amplifier input and will indicate signal across each speaker line even when the MP8 is not powered.

¬ Power Socket:
This 2.1mm socket accepts AC or DC voltage between 12V and 24V. For DC, tip is positive.

4. INSTALLATION
Wiring:
Connect the speaker output of the first amplifier to INPUT terminals labelled AMP 1, maintaining correct polarity. Connect the speaker load for this amplifier to OUTPUT terminals labelled ZONE 1.
Repeat for additional amplifiers and speaker loads.
Always use appropriate cable for amplifier to MP8 and MP8 to speaker wiring.
Power Requirements:
The MP8 can operate on the supplied plug pack and/or separate 24V DC power supply.
A NOTE ABOUT GROUNDING: It may be necessary in some circumstances to ground the MP8 to eliminate noise from the monitor speaker. This can be done using the negative terminal of the 24VDC IN binding post or by making sure that the chassis is electrically connected to the equipment rack (which should be grounded).
A NOTE ABOUT SPEAKER ISOLATION: When a zone is selected for monitoring it is isolated from the other amplifiers by 1kohm resistors. The negative input is also AC referenced to chassis ground with a capacitor.

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.
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.
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.
