MOH AMPLIFIER FUNCTIONS
MOH AMPLIFIER
a) The MOH Amplifier can only receive programs from
INPUT 2 or INPUT 3.
b) Selection of the input source is by rear panel ZONE 1
Switch.
c) The two independent 600 Ohm and 8 Ohm Outputs
may be used simultaneously.
d) The MOH 600 ohm Output is Transformer Balanced.
e) The Rear Panel ZONE 1 Level Control operates both
the 600 Ohm and 8 Ohm Outputs simultaneously.
MOH AND ZONE 1-2 OPERATION ISSUES
1) Paging from the Microphone Input or the Telephone Input
(INPUT 1) does not effect the MOH/ZONE 1-2 Amplifier.
2) Position of the INPUT 2 and the INPUT 3 Level Control
does not affect the MOH/ZONE 1-2 Amplifier Output Level.
3) Position of the INPUT 2 ATTENUATOR does not affect
the MOH/ZONE 1-2 Amplifier Output Level.
4) Muting of the INPUT 2 or the INPUT 3 Channels during
Paging (from Microphone or Telephone) does not effect the
Output of the MOH/ZONE 1-2 Amplifier.
5) Signal Source from INPUT 2 is sent to the MOH/ZONE
1-2 Amplifier only if the INPUT 2 Switch is set on PROG.
ZONE 1 OUTPUTS - 600 Ohm MOH AND 8 Ohm
The Integrated Amplifier is equipped with an independent 1 Watt
Amplifier that can be utilized as a MUSIC ON HOLD AMPLIFIER
and as a SECOND ZONE AMPLIFIER. The MOH Output provides
a 600 ohm, 1 Volt Transformer Balanced Output. Simultaneously a
Second Zone 8 ohm, 1 Watt Output may be utilized to drive up to
4 Speakers.
MOH AND 8 Ohm AMPLIFIER INPUT SOURCE SELECTION
The program source for the Input of the 600 ohm MOH Output and
the 8 ohm Output can be selected from either INPUT 2 or INPUT
3 source. Set the Independent ZONE 1 SOURCE SWITCH to the
desired INPUT (2 or 3).
OUTPUT LEVEL CONTROL
Adjust the ZONE 1 Output Level Control to the desired level.
