Gnd. ­2­ FUNCTIONS 1 CROSSOVER POINT SELECTOR (SUBWOOFER) Controls the subwoofer output frequency at 45,80,150,200Hz 2 SUBWOOFER INPUT SWITCH When your car radio has subwoofer output to connect the unit's subwoofer input;Push the switch to the "OFF" Position. If your car radio only has line output to connect the unit 's line input; Push the switch to the "ON" Position ­3­ 3 PHASE SHIFTER SELECTOR (SUBWOOFER) Allows you to change the phase of your subwoofer from 0 to 180 degrees to help compensate for timing differences between drivers. 4 BASS BOOST CONTROL (40Hz) Frequencies around 40Hz can be boosted at the maximum of +10dB. 5 STEREO/MONO SELECTOR (SUBWOOFER) Set the selector to MONO to make subwoofer output monaural. 6 FLAT CHANNEL GAIN CONTROL By turning this control clockwise you increase flat channel level. 7 SUBWOOFER GAIN CONTROL By turning this control clockwise you increase subwoofer channel level. 8 MIDDLE RANGE CROSSOVER POINT SELECTOR The high Pass frequency(100,150,200Hz,Flat) should match the low crossover point, the low frequency(2.5k,3.5k,5k,Flat)should match the high crossover point. 9 MIDDLE RANGE GAIN CONTROL By turning this control clockwise you increase middle range channel level. 0 PHASE SHIFTER SELECTOR(HIGH PASS) Allows you to change the phase of your high pass from 0 to 180 degrees to help compensate for timing differences between drivers. q HIGH PASS CROSSOVER POINT SELECTOR Control the high pass output at 2.5k,3.5k,5k,7k. w HIGH PASS GAIN CONTROL By turning this control clockwise you increase high pass channel e POWER ON INDICATOR The LED light up when the units is powered on. ­4­ FUNCTIONS r SUBWOOFER INPUT CONNECTORS t FRONT INPUT CONNECTORS y FLAT OUTPUT CONNECTORS u SUBWOOFER OUTPUT CONNECTORS i MIDDLE RANGE OUTPUT CONNECTORS o HIGH PASS OUTPUT CONNECTORS ELECTRONIC CONNECTIONS & WIRING Power connection · B + ( l 2 V ) :Connect a red wire(at least l0-12 gauge)to the car battery or other power source. · REMOTE :Connect an orange wire to remote activating(l2V DC)wire of car stereo or equalizer. · GND :Connect a black wire(at least l0-12 gauge)to the car chassis for ground connection. ­5­ ELECTRONIC CONNECTIONS & WIRING Signal connection ­6­ TROUBLE SHOOTING SECTION 1. SIGNAL PROCESSOR DOES NOT TURN ON: Check all fuses. Check all power(positive ,remote) wire connections. Check that ground wire is properly connected. 2. LED POWER ON INDICATOR NOT GOING ON: Same as sign l remedy. 3. SOUND DISTORTION AT LOW VOLUME LEVEL: Output level not set correctly. 4. LEVEL OF SOUND IS LOW: Check input gain control ,match to deck output. Check the RCA patch cords for loose or misconnected cables. 5. A WHINING SOUND CAN BE HEARD THROUGH THE SPEAKERS AT LOW VOLUME LEVEL WITH RUNNING ENGINE: Check the power wire(red)with good connection directly to the battery and ground point must make good contact with chassis ground.
