INPUT SENSITIVITY (LEVEL) CONTROL (Fig.2)
In order to achieve maximum signal-to -noise performance, this control adjusts the signal
level from your Car Stereo/Source, to match the Amplifier’s sensitivity. It is NOT a volume
control.
To adjust, proceed as follows:
a. Set INPUT LEVEL Control at mid-point.
b. Listen for audible distortion as you increase the Car Stereo VOLUME control. If none
is heard, turn the adjustment level control toward to “MAX” in stages, until the onset of
audible distortion is heard, then decrease to “MIN” level prior to the immediate
point of audible distortion.
c. If distortion is immediately heard, turn control to “MIN” until the sound is clear.
NOTE:
NOT PERFORMING ABOVE ADJUSTMENT PROCEDURE AND/OR SIMPLY SETTING THIS CONTROL AT OR NEAR
“MAX” POSITION, MAY INDUCE ELECTRICAL AUDIO NOISE INTO THE SYSTEM.
