OPERATIONS AND SPECIFICATIONS - 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 switch 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. • Set the gain control to “NORMAL” when this amplifier is connected to a Pioneer car stereo with RCA output jacks. If the sound level is too low or distorts, adjust the gain control. • Adjust the gain control to the “MIN” side of “NORMAL” when this ampli- fier is connected to a Pioneer car stereo (High voltage output type). Power Indicator The power indicator lights when the power is switched on. RCA Input Select Switch For two-channel input, slide this switch to the left. For four-channel input, slide this switch to the right. Cut Off Frequency Control If the LPF/HPF select switch is set to LPF or HPF, you can select a cut off 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) * — 50 to 120 Hz Sub-woofer Connect a sub-woofer. OFF (center) Full range Full range HPF (right) * 50 to 120 Hz — Full range Use if you want to cut the very-low-frequency range* because it is not necessary for the speakers you are using. * See the “Cut Off Frequency Control” section. 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 21 GM-X624, GM-X524 Connection Diagram Fuse (30 A) Grommet RCA input Special red battery wire [RD-223] (sold separately).
