ZONE 1 AND 2 OPERATION
The Amplifier is equipped with two independent 1 Watt, 8
ohm Outputs designated ZONE 1 (Reference 4) and ZONE
2 (Reference 5). The Outputs may be utilized to power up to
4 speakers in various combinations as described in the dia-
grams on the next page. This feature will provide a SEC-
OND and THIRD ZONE (in addition to the main output) with
up to 1 Watt of output power and will amplify only the
Source from either AUX 1 - AUX 2 or MODULE (see input
source selection) and will not be affected by the Paging
(from MIC or TEL), VOX or MUTING.
It can be used in any area (up to 1 Watt) where only a
Program Source is desired uninterrupted by Paging.
CABLE
Use an AWG 18 jacketed, twisted pair cable.
ZONE 1 AND 2 OPERATION ZONE 1 AND 2 SETTINGS
INPUT SOURCE SELECTOR
Independent JUMPER SETS for ZONE 1 (SW702) and
ZONE 2 (SW701) are available to select the Input Source
for the two 1 Watt Amplifiers.
DUAL PROGRAM SOURCE CAPABILITY
If desired separate program Sources may be used for
ZONE 1 and ZONE 2.
EXAMPLE: Use the program source from AUX 1 for ZONE
2 and the program source from AUX 2 for ZONE 2.
Select the Input Source desired by following the instructions
in the MOH Amplifier Source Selection section.
LEVEL CONTROL
After the wiring is completed adjust the ZONE 1 (
Reference
