Otherwise malfunction may result. 6 SIGMA SERVO FEED BACK terminals (See p.8) 2CAUTION Be sure to make proper connections to the SIGMA SERVO FEED BACK terminals. Incorrect connection may result in lack of sound output or other malfunctions. 7 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. 8 LOW PASS FILTER FREQUENCY control This control adjusts the frequency band output from this unit. 9 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. 15 0.3 0.2 0.5 1 2 345 (V) (W) 25 10 4 English NOTE For the pre-output level or the maximum power output, refer to the “Specifications” in the instruction manual of the center unit. 0 RCA cable ground lead terminal ! LINE IN terminal @ Speaker level input terminals Power indicator ¦ Power indicator: When the power is turned on, the Power indicator lights. 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. ¦ The protection function is activated in the followingsituations: This unit is equipped with a protection function for protecting this unit and your speakers from various accidents or problems that can occur. When the protection function is triggered, the Power indicator goes off and the amplifier stops operating. • A speaker cable may be short-circuited. • A speaker output may be in contact with the ground. • The temperature of the internal parts may be higher than 120°C (248°F). • The sigma servo connection may be erroneous. • The fuse of this unit may be blown. • The unit may be malfunctioning and sending DC signal to the speaker output. • The grounding cable of this unit may not be connected with a metallic part which is electrically connected with the negative terminal of the battery. • The power control cable may not be connected to this unit. • The grounding cable of the center unit (cassette receiver, CD receiver, etc.) may not be connected with a metallic part which is electrically connected with the negative terminal of the battery.
