2CAUTION • If sound is not output normally, immediately turn power off and check connections. • Be sure to turn the power off before changing the setting of any switch. • If the fuse blows, check wires for shorts, then replace the fuse with one of the same rating. • Check that no unconnected wires or connectors are touching the car body. Do not remove caps from unconnected wires or connectors to prevent short circuits. • Connect the speaker wires to appropriate speaker connectors separately. Sharing the negative wire of the speaker or grounding speaker wires to the metal body of the car can cause this unit to fail. NOTE • Do not connect cables and leads to both RCA cable input jacks and the speaker level input terminals simultaneously, for this may cause malfunction or damage. Speaker level input connections • The genuine-accessory car stereo shall have a maximum power output of no more than 40 W. • The power is turned on and off as the unit detects input signal (Signal Sensing Turn-ON). There fore it is not necessary to connect the power control wire. Speaker output terminals • As this unit accepts speakers with a minimum impedance of 2 ohms, connect speakers with 2- ohms or higher impedance to these terminals. LINE OUT terminal • The signal that’s input from the line input terminal is output.

If the Power indicator does not light when the power is turned on, the protection function may be activated. Check whether there is any indication of trouble. Refer to (page 3). 2 Illumination 3 ISF (infrasonic filter) switch Ultralow frequencies that cannot be reproduced even by a subwoofer speaker do not become sound but become unnecessary oscillations, which affect the sound by causing distortion, etc. Setting this switch to "15 Hz" or "25 Hz" cuts the frequencies below the respective frequency. This improves the reproduction performance of the speakers by eliminating unnecessary oscillations which will not become sound. 4 BASS BOOST LEVEL control Sets the low frequency level to be compensated. 5 LPF(Low-Pass Filter) FREQUENCY control This control adjusts the frequency band output from this unit. 6 INPUT SENSITIVITY control Set this control according to the pre-output level of the center unit connected with this unit, or to the maximum power output of the genuine-accessory car stereo. Use the diagram on the right as a guide. 40 .. .. .. .. .. .. .. 40W – 15W Troubleshooting Guide What might appear to be a malfunction in your unit may just be the result of slight misoperation or miswiring. Before calling service, first check the following table for possible problems. No sound. (Blown fuse.) . Input (or output) cables are disconnected. . Connect the input (or output) cables. . Protection circuit may be activated. . Check connections by referring to . . Volume is too high. . Replace the fuse and use lower volume. . The speaker cord is shorted. . After check the speaker cord and fixing the cause of the short, replace the fuse. The output level is too small (or too large). . The input sensitivity adjusting control is not set to the correct position. . Adjust the control correctly referring to . The sound quality is bad. (The sound is distorted.) . The speakers wire are connected with wrong 9 / · polarity. . Connect them properly checking the 9 / · of the terminals and wires well. . A speaker wire is pinched by a screw in the car body. . Connect the speaker wire again so that it is not pinched by anything. . The switches may be set improperly. . Set switches properly by referring to .
