Input Wiring

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.

NOTE: 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 and RCA connectors beneath the left side access cover. Loosen the two Phillips-head screws on each side of the cover and remove it.

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 and COM. Shorting these terminals together will mute the background music input and open the Tel page channel (see Figure 4).

NOTE: In instances where the amplifier is to be placed permanently in the Tel page mode, a wire jumper must be installed between the TEL and COM terminals.
