PROGRAM INPUT
The PROGRAM Input is a balanced high level input (1 Volt
Sensitivity) provided specifically for direct connection to a
Satellite Receiver with a balanced Output or other high
level Balanced Program Source. An independent Output
Level Control is provided on the front panel of the Amplifier.
CABLE
To connect the Satellite Receiver to the PROGRAM Input
use a dual conductor shielded audio cable with stripped
wires on both ends. Connect the audio leads to HOT and
COM and the shield to G.
Balanced
NETWORK APPLICATION
In applications requiring the use of multiple Amplifiers with
a single Satellite Receiver, the Balanced Program Input of
the Amplifier may be used. The Amplifiers are cascaded as
shown in Diagram 13B and then connected to the Satellite
Receiver Balanced Output.
The Music Output Level may be adjusted by using the
PROGRAM Output Level Control available on the front
panel of each Amplifier.

WIRING
To connect the Satellite Receiver to the Amplifiers PRO-
GRAM Input use a dual conductor shielded audio cable
with stripped wires. Connect the audio leads to HOT and
COM and the shield to G.

The PROGRAM Input can be Muted or not when the VOX
is activated by Paging from the MIC Input or the Phone
Input. The same occurs when the Direct Muting is applied.
