MOH/ZONE 1 AMPLIFIER SOURCE SELECTOR
MOH AMPLIFIER
An independent 600 ohm, 1 Volt Output, Transformer Balanced
MUSIC-ON-HOLD Amplifier is provided. The Input SOURCE of the
MOH Amplifier can be selected from either the AUX 1 or AUX 2.
MOH - 600 OHM SYSTEM
Most Phone systems operate on a 600 ohm Input Impedance, if the
Impedance required is 600 ohm connect the Amplifier to the Phone
System MOH by using the diagram above (Reference 3).
MOH - 8 OHM, 1 WATT SYSTEM
Some older Key Phone systems require a 1 watt Power Output having
an Output Impedance of 8 ohm to drive the Music on Hold feature. If
the Impedance required is 8 ohm connect the Phone system MOH to
the 8 ohm, 2 Watt MOH Output of the Amplifier (Reference 4).
CABLE
Use a cable consisting of a twisted pair of at least AWG 18. Use care
in extending the cable and avoid routing near power lines, fluorescent
lights and other systems that may generate a disturbing electric field.
SOURCE SELECTOR
Select the Input Source desired by following the instructions at right.
CAUTION: REMOVAL OF THE COVER PRESENTS AN ELECTRI-
CAL SHOCK HAZARD !
MUSIC ON HOLD AMPLIFIER
MOH/ZONE 1 SOURCE SELECTOR
The Source for the MOH/ZONE 1 Amplifier can be selected

2) Remove the three screws on each side of the amplifier
holding the amplifier cover.
3) Lift Cover and locate the Jumpers Set No S107 on the

Amplifier Level Controls on the rear panel to the desired out-
put level (Reference 1 and 8).
