UNPACKING AND INSTALLATION
Although it is neither complicated to install nor difficult to operate your power Amplifier, a few minutes of your
time is required to read this manual for a properly wired installation and becoming familiar with its many features
and how to use them. Please take a great care in unpacking your set and do not discard the carton and other
packing necessary to return your set for when moving your set and are required if it ever becomes necessary to
return your set for service. Never place the unit near radiators, in front of heating vents, to direct sun light, in
excessive humid or dusty location to avoid early damage and for your years of quality use. Connect your
complementary components as illustrated in the following page.

FEATURES
• SPEAKER LINE CONTROL
Speaker line control can easily be achieved by connecting the RM-916 speaker control terminals to an Inter-M
PX-9116 MATRIX unit.
• CHIME
Four tone pre-announcement chime, activ ated b y push button CHIME switch.
• OUTPUT LEVEL METER
Ten segment LED bargraph on the front panel that indicates instantaneous signal output level of the RM-916.
• MIC BROADCASTING
Easy to use, highly sensitive condenser type MIC for clear broadcasting.
•AUXILIARY SIGNAL INPUT
Auxiliary signal input for Cassette Deck or Tuner makes the RM-916 an ideal remote piece of equipment for
broadcasting background music.
OPERATING PROCEDURE
1. Switch the RM-916 on with the POWER switch. The POWER LED will illuminate.
2. If the announcement is to be broadcast to one of the sixteen loudspeaker zones, press the corresponding
channel switch. The selected channel switch LED will illuminate.
3. If the announcement is to be broadcast to all the sixteen loudspeaker zones, press the ALL call switch. The
ALL call switch LED will illuminate.
4. Press the CHIME s witch for the pre-announcement chime, if required.
5. You can now use the CM-916 MIC for broadcasting across the system.
6. Adjust the v olume to its required level using the relev ant MIC, CHIME or AUX control.
7. When the announcement is finished, Turn off all the channel switches (CH1–16) and the ALL call switch to
ensure that normal broadcasting can take place. The sixteen channel switch LEDs and the ALL call switch
LED will be extinguished.

2. Site the equipment in well v entilated places and a void places of high humidity.
3. Whenever possible, fit Inter-M MIC model CM-916. If a Phantom powered MIC is to be used, we recommend
that it operates on +5V DC.
4. Please observe wiring polarity when connecting DC Pow er to the equipment.
5. Before connecting to the RM-916 LINE OUT terminals, check and match the incoming wiring for HOT, COLD
& GND potential.
