Installation
The amplifier is designed for wall mount applications. The 10-watt amplifier weighs
4 lb.
NO
TE: The amplifier will produce heat during operation which will rise and may
cause problems for temperature-sensitive equipment mounted above it. Mount the
amplifier near the top of the backboard so that no other equipment will be above it.
If this is not possible, then allow at least 12" between the top of the amplifier and
the bottom of any equipment positioned above it. Also allow at least 4" between the
bottom of the amplifier and any equipment below it to allow for adequate air
circulation. In addition, because the unit itself gets hot, avoid touching it during
operation.
Wall Mounting To wall mount this unit, use the two 5/8” pan head screws with nylon washers
provided.The screws should protrude approximately ¼" from the surface of the
backboard. Lift the amplifier and place it over the two screws using the keyhole
slots in the flanges at the sides of the amplifier.The screws should engage the
keyhole slots. Once in the keyhole slots, tighten the screws to secure the amplifier.

Wiring Connections
IMPORTANT: Before making any connections or wiring changes to the amplifier
or any equipment connected to the amplifier, make sure that the amplifier is NOT
plugged into an AC outlet.
NO
TE: The amplifier does not have a power switch, so it must be unplugged in
order to turn the power off.
All signal input and control wiring is made to the terminal strip on the front of the
unit.
TEL Input and Control Pair The telephone input is a 600-ohm, dry loop, balanced input available at the T and R
terminals.It is controlled by a dry contact closure that is made between the control
terminals labeled TEL CONT and GND.Shorting these terminals together will mute
the background music input and open the Tel page channel (see Figure 2).
NO
TE: In instances where the amplifier is to be placed permanently in the Tel page
mode, a wire jumper must be installed between the TEL CONT and GND terminals.
