Important Use either the low level or the high level input, do not use both at same time. Low level input Use a pair of shielded stereo audio cables with RCA type jack.

CAD11, CAD15 Bass boost control Bass boost control is used to set the bass volume. You can select the amplification between 0 dB and +18 dB at a 45 Hz center frequency. This function is used to compensate for the bass box function and to adjust for your own taste of bass. Set level control at 0 dB if you want it to be inoperative. Remote Bass level control Bass Boost You can fine tune your bass level from the front of your car.

CAD15 Professional Tip: Professional Tip: NOISE PROBLEMS SPEAKER POLARITY CHECK. WHINING NOISE VARYING WITH ENGINE REVOLUTIONS: All speakers in a car audio system should be connected in phase (the same polarity). All speaker cones must move in the same direction. Out of phase speakers will cause a lack of bass, and a poor stereo soundstage. Do this: 1. Rewire the power supply (12 V) to source unit direct from battery. 2. Rewire ground wire from source unit to clean position on chassis. 3.
