7. High Level Inputs
8. Input Gain Level Control
For adjusting the output of the amplifier to the input of the source unit. Adjustment range is from 0.2V to 8.0V.
9. 24dB Low Pass Variable Control
Adjustable low pass crossover frequency from 50Hz-250Hz
10. Bass control
11. Protection LED
The Red color LED indicates fault condition of amplifier.
When a fault condition occurs such as an overload, excessive heat or short circuit of speaker
terminals, the protection circuit is engaged to protect both the subwoofers and amplifier.
12. Power LED
The Blue color LED indicates that the power is on.
13. 24dB High Pass Variable Control
Adjustable high pass crossover frequency from 50Hz-250Hz
14. Crossover
HIGH/LOW PASS VARIABLE CROSSOVERS (50HZ-250HZ)
a) For use as a dedicated subwoofer channel(front or rear),select Lo pass switch. This activates the
low pass filter circuitry.
b) For us as a mid to hi range channel(front or rear),select Hi pass switch. This activates the hi pass
filter circuitry.
c) For normal full-range amplifier use, set to “FULL”.
CONNECTING HIGH LEVEL INPUTS
NOTE: DO NOT CONNECT THESE HIGH LEVEL INPUT WIRES IF YOU ARE USING THE LOW LEVEL INPUT RCA
JACKS.
YELLOW
: Connect to Right (+) Speaker output of Car Stereo
WHITE
: Connect to Right (-) Speaker output of Car Stereo
GREEN
: Connect to Left (+) Speaker output of Car Stereo
BLUE
: Connect to Left (-) Speaker output of Car Stereo
BLACK
: Connect to Car Stereo Ground Wire
CONNECTING LOW LEVEL INPUTS
NOTE: DO NOT USE THESE RCA JACKS IN CONJUNCTION WITH HIGH LEVEL INPUT WIRES.
1. Always use high quality RCA type shielded cables
2. Always use the shortest length possible. If the cable is too long, make an “S” shape 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 or parallel to speaker outputs, high energy ignition
wires, or 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 GREEN LED will illuminate whenever the Amplifier is turned “ON”. If it fails to illuminate, check
the power connections to the Amplifier and fuses.
PROTECTION CIRCUIT
Should the amplifier become shorted, overloaded or overheated, the protect circuit will “SHUT-DOWN”
