INPUT
Tel Input to Universal Coupler After properly connecting your Universal Coupler (909) to your Auxiliary Trunk
port, set your switches as follows: C1/C2 to C2; Rocker Switch 3 closed; and all
others open. Coming out of the J2 Jack of the Coupler, connect the blue/white pair
to the amplifier’s T and R terminals.
Music Input A pair of terminals are provided for the connection of a background music source.
Use a pair of wires (not included) to make this connection. This is a mono input and
requires that the output of stereo sources be converted to mono by using a Y-
adapter (not included). Use a LUWMT1A (COM Code: 405891680) to balance the
music input, if necessary, to reduce hum/noise from a grounded music source.
Night Bell Connection An external contact closure activates the night bell function of the amplifier. When
using an external contact closure, connect the closure pair across the Night Bell
terminal and GND. The night ringer follows the cadence of the activating signal.
CAUTION: Do not apply a high voltage (90-105V AC, 20-30Hz) ring signal to the
Night Bell terminals. Use a dry contact closure only.
