Avaya LU250WAMP manual Microphone Cable

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 Tip and Ring. Connect the brown/white pair to Tel and Com on the control terminals.

Music Input A single RCA connector is provided for the connection of a background music source. Use a male RCA-to-RCA cable (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 to balance the music input, if necessary, to reduce hum/noise from a grounded music source.

Microphone Input A high gain, low impedance microphone input is provided in this amplifier. It is designed to work with microphone LUSZMIC (Com Code: 408186238, PEC Code: 5335-400). Connect the microphone's black wire to the amplifier's "-" (negative) terminal under the MIC BAL connections. Connect the microphone’s Red wire to the "+" (positive) terminal. Connect the shield wire from the microphone to the adjacent GND terminal. Connect the microphone's white lead to the Control terminal marked MIC and the green lead to the COM. (See Figure 5.)

Two conductor shielded microphone wire should be used to extend the cable from the microphone. 22 AWG shielded, twisted pair speaker cable (Com Code: 401882956, PEC Code: 2734-SPK) will also work. When extending microphone cable, be sure to connect the shields of the microphone cable to the extension wire.
