Cut Off Frequency Control Power Indicator
The power indicator lights when the power is switched on. If the LPF/HPF select switch is set to LPF or HPF, you can select a cut off
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.
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 Switch
LPF (left) OFF (center) HPF (right)
· 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 amplifier is connected to a Pioneer car stereo (High voltage output type).

Remarks
Connect a sub-woofer. Use if you want to cut the very-low-frequency range* because it is not necessary for the speakers you are using.
For two-channel input, slide this switch to the left. For four-channel input, slide this switch to the right.
* See the "Cut Off Frequency Control" section.
