ZONE 1 AND 2 OPERATION
The Amplifier is equipped with two independent 1 Watt, 8 ohm Outputs des-
ignated ZONE 1 and ZONE 2. The Outputs may be utilized to power up to
4 speakers in various combinations as described in the diagrams on this
page. This feature will provide a SECOND and THIRD ZONE (in addition to
the main output) with up to 1 Watt of power and will amplify only the Source
from either INPUT 2 or INPUT 3 (see source selection) and will not be
affected by the Paging (from MIC or TEL) 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.
SOURCE SWITCH SELECTOR
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 and 2 Level Controls on
the rear panel to the desired output level.
