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.
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 2 Phillips-head screws on each side
of the cover and remove it.
TEL Input
The telephone input is a 600-ohm, dry loop, balanced input available at the T and R
terminals. Automatic music mute is provided when making a telephone page.
