REAR PANEL
1) AC accessory outlet (Unswitched). Unswitched AC Auxiliary outlet for a 120VAC 50/60Hz
power source.
2) AC fuse holder.
3) MOH output terminals. Provided two MOH output 600 Ohm, 1 Volt and 8 Ohm, 1 Watt.
4) MOH output level control. Controls volume of MOH output. (Music on hold)
5) Contour control on/off switch . Contour switch for AUX-1~3, +8dB @100 Hz,+4dB @10 KHz.
6) AUX output RCA jacks. Provides connection for a booster amplifier. The input impedance of the
equipment should be more than 600 Ohms.
7) AUX-3 input RCA jacks. High impedance input available with parallel RCA jacks. (for
combining stereo output accessories).
8) MIC-3/AUX-3 input selector switch. Allows for selection of either high impedance AUX-3
input or low impedance MIC-3 input.
9) AUX-2 input RCA jacks. High impedance input available with parallel RCA jacks. (for
combining stereo output accessories).
10) MIC-2/AUX-2 input selector switch. Allows for selection of either high impedance AUX-2
input or low impedance MIC-2 input.
11) AUX-1 input RCA jacks. High impedance input available with parallel RCA jacks. (for
combining stereo output accessories).

input or low impedance MIC-1 input.
13) Paging output level control. Controls audio level of telephone output.
14) MIC-1 (XLR connector) input. Accepts a balanced low impedance microphone signal with
an XLR connector.
15) MIC-1 VOX on/off switch: Allows for disabling of MIC-1 input VOX muting of the MIC2~3
and AUX-1~3 input during paging. This allows for multiple MIC pagng/operation.
16) TEL/PAGING balanced input terminals. Accepts a balanced telephone signal.
17) MIC-1 balanced input terminals. Accepts a balanced low impedance microphone signal.
18) MIC-2 balanced input terminals. Accepts a balanced low impedance microphone signal.
19) MIC-3 balanced input terminals. Accepts a balanced low impedance microphone signal.
20) Manual muting terminals. Provides contact closure muting of the AUX-1~3 and MIC-2~3
input during paging.
21) Speaker outputs. Speaker lines must be connected to “COM” and one (and only one) of
the remaining screw terminals.
