- SETTING THE UNIT
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.
BFC (Beat Frequency Control) Switch (ES and EW models)
If you hear a beat while listening to an AM broadcast with your car stereo, change the BFC switch using a small screwdriver.
· 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 is too low or distorts, adjust the gain control.
