OPERATIONS Power Indicator The power indicator lights when the power is switched on. BFC (Beat Frequency Control) Switch (GM-X574/XR/EW,X574/XR/ES) 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. LPF (Low-Pass Filter)/HPF (High-Pass Filter) Select Switch Set the LPF/HPF select switch as follows according to the type of speaker that is connected to the speaker output connector and the car stereo system: LPF/HPF Select Audio frequency range Speaker Remarks Switch to be output Type LPF (Left) Very Low Frequency range Subwoofer Connect a subwoofer. OFF (Center) Full range Full range HPF (Right) Low Frequency range to Full range Use if you want to cut the High Frequency range very low frequency range because it is not necessary for the speakers you are using. Input Select Switch For two-channel input, slide this switch to the left. For four-channel input, slide this switch to the right. 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-clock- wise. • 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. • If you hear too much noise when using the speaker input terminals, turn the gain control counter-clockwise. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 25 Connection Diagram Fuse (30 A) Grommet RCA input Special red battery wire [RD-223] (sold separately) After making all other connections at the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery.
