• HPF (High Pass Filter) position Only frequencies of 150 Hz or higher are output. (Frequencies below 150 Hz are cut.) • LPF (Low Pass Filter) position Only frequencies of 80 Hz or lower are output. (Frequencies above 80 Hz are cut.) The Lch and Rch will be mixed before output even if the operation switch is set to STEREO. • OFF position The original sound without filtering is output. #INPUT SELECTOR switch This switch selects the input method of the signals to be amplified by amplifiers A and B. • A B position: Amplifies both of the signals input to amplifiers A and B. • A position: Amplifies only signal input amplifier A with both amplifiers A and B. 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 following situations: 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. • When a speaker wire may be short-circuited. • When a speaker output contacts ground. • When the unit malfunctions and a DC signal is sent to the speaker output. • When the internal temperature is high and unit won’t operate. • When a ground wire of the center unit (cassette receiver, CD receiver, etc.) or this unit is not connected to a metal part serving as an electrical ground passing electricity to the battery's negative -terminal. 2CAUTION NOTE Controls 25 LEFT BRIDGED POWER IN SPEAKER FUSE(25A) BATT.

(Low pass) Capacitor (C): Passes high frequencies and blocks low frequencies. (High pass) Example: When it is required to set a crossover frequency of 120 Hz using speakers with an impedance of 4 ohms. fc=Cut of Frequency (Hz) R=Speaker Impedance (.) • If you wish to bridge-connect a speaker, the speaker impedance must be no less than 4 ohms. Connecting a speaker with an impedance lower than 4 ohms may damage the unit. • Be sure to connect capacitors to speakers to which high frequencies will be passed. Failure to do so will result in a drop of the combined impedance with the subwoofer. • Ensure that the withstand voltage and current ratings of the capacitors (C) and coils (L) are sufficient. 2CAUTION ...
