5. Input Sensitivity Adjustment
This control adjusts the amplifier’s sensitivity to match the signal strength coming from the
source unit. Input sensitivity is variable from 200 Millivolts to 8 volts. Clockwise increases
sensitivity. Counterclockwise decreases sensitivity. THE KNOB IS NOT A VOLUME
CONTROL. A lower signal level will require increased sensitivity for full power. A higher sig-
nal will require decreased sensitivity.
6. Low Level Input RCA Jacks
These inputs are for signal cables from the source unit or other processor. Always use
high quality shielded RCA cables.
7. Low Level OUT RCA Jacks
The LINE OUT allows you to build multiple amplifier systems without having to use splitter
cords to distribute the signal. Now it is a simple matter of bridging one set of RCA cables
into the first amplifier, then using the line out RCA jacks as the feed to the next amplifier.
8. LED indicator (Status)
- PRT (Protection) : The amplifier protection circuitry will disable the amplifier if input
overload, short circuit, or extremely high temperature conditions are detected. When the
protection mode is in operation, the LED indicator on the side panel will be illuminated,
indicating the amplifier has gone into a self-preservation mode.
-PWR (Power) : This LED will illuminate when the amplifier is turned “ON”. If it fails to il -
luminate, check the power connections to the amplifier and fuses.
