Setting the Unit Gain Control Adjusting the gain controls A and B will help match the output of the car stereo to the Pioneer amplifier. Normally, set the gain controls to the "NORMAL" position. If the output is low, even when the volume of the car stereo is turned up, turn these controls clockwise. If there is distortion when the volume of the car stereo is turned up, turn these controls counter-clockwise. • If you only use one input plug, set the gain controls for speaker outputs A and B to the same position. • When using with an RCA equipped car stereo (standard output of 500 mV), set to the NORMAL position. When using with an RCA equipped Pioneer car stereo with max. output of 4 V or more, adjust level to match the car stereo output level. Power Indicator The power indicator lights when the power is switched on. Cut Off Frequency Control Combining LPF/HPF/BPF and LOW/HIGH select switch settings lets you select between cut off frequencies from 40 to 120 Hz and 3k to 9k Hz. (Example: LPF and HIGH) (dB) 0 -3 Level (3 kHz) (9 kHz) Frequency (Hz) 3 BFC (Beat Frequency Control) Switch If you hear a beat while listening to an MW/LW broadcast with your car stereo, change the BFC switch using a small standard tip screwdriver.
