Use good quality shielded audio cables with RCA plugs at both ends to connect the stereo to the amplifier and keep the cable lengths to a minimum to avoid noise. If the car stereo does not provide low-level outputs, the amplifier may be connected via the speaker (high-level) outputs from the stereo. Wire the speaker leads from the car stereo to the 5-pin adaptor harnesses as shown in the diagram (shielded cable is not required for this application) and plug the connectors into the mating High-Level Input socket on the amplifier. Carefully splice and insulate all wire connections. CAUTION: Use either the low-level or the high-level inputs on the amplifier. DO NOT use both input levels at the same time. -7 HI-INPUTHI-INPUT GNDGND L+L + R+R + LL RR RR LL PWRPWR PRTPRT MINMIN MAXMAX GAINGAIN 40Hz40Hz 80Hz80Hz BASSBOOSTFRQBASS BOOST FRQ XOVERX OVER LPFLPF FULLFULL CAR STEREO White Green Black Brown Gray HIGH-LEVEL (SPEAKER) INPUT (WIRE SIDEVIEW) LOW-LEVEL INPUT Right SpeakerLeft Speaker RCA TYPE SHIELDED EXTENSION CABLES (NOT INCLUDED) USE EITHER HIGH-LEVEL OR LOW-LEVEL INPUT, NOT BOTH.

The protection circuits may be triggered By the temperature of the unit rising above a safe level or by an overload condition. If activated by a rise in temperature, the unit will resume operation after cooling U UUS SSE EE SPEAKER1 SPEAKER2 BATT REM GND Off to a normal operating range. If activated by an overload condition, the source of the overload must be found and corrected to resume operation of the amplifier. Most overload conditions are caused by mis-wiring or operation into incorrect speaker loads. Re-check all wiring and connections if this situation occurs and correct as necessary. 3 Level (Gain) Controls The amplifier is capable of operating from sources supplying a wide range of input levels. The Level controls should initially be set to the mid-rotation position. If it is found that there is not enough output even when the volume control on the car stereo is at its maximum setting, adjust the Level control to increase the output from the system. -10 4 4 5 If, however, there is still output from the amplifier when HPF Crossover Frequency Control the car stereo volume control is at its minimum setting, 6 This Control selects the crossover frequency when the 4or the output level increases too fast with a small Sub woofer Crossover Selector is in the "HPF" setting. rotation of the volume control, adjust the Level control Adjust it to the appropriate position for the characteristics to decrease the output from the system. and crossover frequency requirements of the speaker Once the correct setting is found, these controls should system with which the amplifier is being used. not require any further adjustment. 7 8 Bass Boost Frequency Control Sub-Woofer Crossover Selector Allows the addition of up to +18dB increase in sound This switch allows selection of the frequency filters that level in lower frequencies (0~1...
