F.CONNECTING LOW LEVEL INPUTS (RCA Jacks)
NOTE:
DO NOT USE IN CONJUNCTION WITH HIGH LEVEL INPUT WIRES.
Wire routing is CRITICAL for NOISE FREE PERFORMANCE,Observe the following:
1.Always use high quality RCA type shielded cables.
2.Always use the shortest lenght possible.If the cable is too long,make an S type
loop(not a coiled loop)in the center of the cable to take up any excess.
3.Never cut the shielded cable and re-splice it.
4.Never route any Amplifier input cables near nor parallel to speaker outputs,high
energy ignition wires,nor near computer controlled ignition circuit units (Computer
units may be found behind or under the dash panel in late model cars).
POWER INDICATOR LED
This METER LAMP will illuminate when the amplifier is turned ON .If it fails to illuminate,
check the power connections to the Amplifier and fuses.
PROTECTION CIRCUIT
Should the Amplifier be SHORT CIRCUITED overloaded or overheated,the protection
circuit will SHUT-DOWN the Amplifier.
CAUTION
THIS AMPLIFIER WAS DESIGNED TO BE USED WITH EITHER 2 OHM STEREO/CHANNEL OR 4 OHM EACH
MONO BRIDGED CHANNEL.IN THE CASE OF TRI-MODE OPERATION,USE EITHER 8 OHM STEREO CHANNEL
SPEAKERS AND 4 OHM SUB OR VICE VERSA.SEE THE SECTION TRI-MODE FOR FURTHER INFORMATION
ON PROPER USE.
INPUT SENSITIVITY(LEVEL) CONTROL
In order to achieve maximum signal-to-noise performance,this control adjusts the signal
level from your Car Stereo/Source,to match the Amplifier sensitivity.It is NOT a volume
control.
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.
To adjust,proceed as follows:
NOTE:
NOT PERFORMING ABOVEADJUSTMENT PROCEDURE AND/OR SIMPLY SETTING THIS CONTROLAT OR NEAR
MAX POSITION,MAY INDUCE ELECTRICAL AUDIO NOISE INTO THE SYSTEM.
