POWER SUPPLY
The Amplifier provides a 24 Volt - 250 mA DC Regulated
Auxiliary Power Supply Output (Reference 7).
CABLE
To connect the Power Supply Output to accessories use a
two conductor wire not less than AWG 18. This minimum
wire gauge is necessary to minimize potential Voltage
Drops in long wire connection applications. For wire resist-
ance refer to Table below.

NOTE:
When calculating the Wire Resistance for each run
using a two conductor Wire the wire Resistance
should be doubled.
EXAMPLE: The Total Resistance of a 1000 Ft. run
of a AWG 24 two conductor Wire is:
25.67 X 2= 51.34 Ohm
REMOTE VOLUME CONTROL
The Amplifier features a Remote Volume Control Capability: The INPUT 3 (AUX
1) Remote Volume (Reference 10). A 10 K ohm Potentiometer is required.
Mount the 10 K Pot on a suitable Wall Plate or any other convenient surface
and connect to the Amplifier RVC Terminals as shown in the Diagram. The
Paso Model RVC10W Decora Style Remote Volume Control may be used.
INPUT 3 (AUX 1) OPERATION
When connected the Remote Volume adjusts the INPUT 3 (AUX 1) Level only.
Usually this input is utilized for the Music Source (Sat. Receiver, CD Player,
etc.).
CABLE
To connect the Remote Control to the Amplifier use a two conductor wire not
less than AWG 20. While the Remote Volume System uses DC rather than
audio caution should be exercised in the layout of the wire. Always avoid rout-
ing next to power lines. If the total wire resistance exceeds 3 K ohm the Volume
may not go down to zero.
