5. PRESET CONTROLS  
A) VOX - P9 (Voice activated switch)  
This pot adjusts the sensitivity of the VOX threshold of the tel/mic input. Make adjustments as follows:  
1) Set the VOX control fully counter clockwise (CCW) (background music should be on).  
2) While someone is talking in the page mode, slowly turn the control clockwise (CW) until  
the VOX circuit triggers and the background music cuts off.  
3) Turn the control an additional 1/8 turn CW and leave at this setting.  
If the VOX function has a tendency to drop out, slightly increase (CW) the control setting.  
B) Noise - P10 (Talkback background noise balance)  
This pot cancels the background noise in the talkback circuit which may be induced into the speaker  
wiring by an outside source. (For use with the PD-2 talkback paging adaptor only.)  
C) Level - P11  
This pot sets the talkback level of the amplifier. (For use with the PD-2 talkback paging adaptor only.)  
6. GROUND TERMINAL  
A chassis ground has been provided to allow separate grounding of the unit, if required.  
7. OUTPUT  
Connect speaker wires to the terminals labelled OUTPUT. The rated output of all amplifiers is 70V RMS.  
Note: To prevent any possible oscillation ensure that the speaker wires are kept away from any input  
wiring connected to the terminal strip described below (Item 9).  
8. TERMINALS 1-9  
In accordance with your particular system installation and requirements, make the following connections  
at the terminal block at the right.  
A) Terminals 1 & 2 - Tel/Mic (Balanced Input)  
Connect to either the telephone system page port, C.O. port, a telephone set or an external microphone  
(600balanced - shield to pin 3) to these terminals. Depending on which source is used, dip switches  
1 & 2 must be set accordingly.  
This voice input can only be activated by the page port dry contacts, the VOX circuit, the C.O. port talk  
battery circuit or a strap across pins 5 & 6.  
CAUTION: This input must NOT be connected directly to the telephone network.  
B) Terminals 3 & 4 - Music/Aux (Unbalanced Input) - (4 - Positive, 3 - Negative)  
Connect a music source to these terminals noting that pin 3 is negative. Reversed connection can cause  
oscillation. It is important that shielded cable be used to avoid any induced hum. If you are using the  
matching PGT-8 tuner, follow the separate instructions included with the tuner. In applications where  
this amplifier is used with an external Aiphone paging adaptor, this input may be used as an AUX  
input with 10K ohms impedance.  
C) Terminals 5 & 6 - Music Mute  
When these two terminals are shorted together, the music/aux output of the amplifier will be muted to  
allow a tel/mic page to be heard.  
D) Terminal 7 - Page C/2  
Connect the appropriate leads from your Aiphone intercom system to this terminal. Refer to the  
following wiring diagrams for more details. Set dip switches 7 & 8 according to your system.  
E) Terminals 8 & 9 - 12/24 VDC  
If an Aiphone intercom system is used in conjunction with this amplifier, connect the matching  
power supply for that intercom system to these terminals. Be sure to observe polarity.  
24VDC: When using the built-in MC-A adaptor.  
12VDC: When using the built-in PD-1/PD-2 adaptor.

INSTALLATION

3
6"  
1. Mount the amplifier on a wall or base plate capable of supporting its weight securely. Be sure no  
heat producing elements are nearby. Also be sure that the area behind the amplifier allows a clear  
path of air to flow and that the air slots at the top and bottom are not obstructed.  
IMPORTANT: To comply with NRTL/C safety regulations, a minimum clearance of 6 inches must  
be maintained above the unit. (See picture at right.)  
2. Loosen, but do not remove the screw at the bottom of the unit to gain access to the terminals and  
switches under the lower cover.  
3. Lift the cover all the way up. In the fully open position you can conveniently refer to the  
labelling which indicates the terminal connections and dip switch settings.  
(Airflow)  
4. Make all the proper connections, determined by which system is being used in conjunction with the amplifier.  
(As you make your connections, the small "plate" rises from the bottom of the terminal to secure the wire.)  
5. Connect the speaker line to the terminals labelled OUTPUT.  
6. Set all appropriate switches and volume levels. (Refer to Names and Functions section.)
