MOH AMPLIFIER
The Integrated Amplifier provides an independent 600 ohm, 1 Volt
Output, Transformer Balanced MUSIC-ON-HOLD Amplifier . The Input
Source of the MOH Amplifier can be selected from either the AUX or
the PROGRAM Input.
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.
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, 1 Watt MOH Output of the Amplifier. See Diagram above.
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.
LEVEL CONTROL
After the wiring is completed adjust the MOH Amplifier Level Control on
the rear panel to the preferred output level.
MUSIC ON HOLD AMPLIFIER
MOH SOURCE SELECTOR
The Source for the MOH Amplifier can be selected between
the AUX and the PROGRAM Input by setting the Jumper pro-
vided for this purpose. The Amplifier is shipped from the
Factory with the Jumper set for the AUX Input. To change the
setting do the following:
ACCESS TO THE MOH INPUT SOURCE SELECTOR
1) Remove Power Cord from AC Outlet.
2) Remove the four screws on each side of the Amplifier
securing the Top Cover to the Chassis.
3) Lift Cover and carefully slide Cover out towards the rear.
4) Locate the Printed Board No. 3130-3 attached to the rear
panel and below the AUX Input Jacks.
5) Set Jumper as required.
MOH ISSUES - The MOH Amplifier is not affected by the
Paging, Muting Functions and AUX/PGM Level Controls.
