Gain Control Power Indicator
The power indicator lights when the power is switched on.
8. OPERATIONS
1
1
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.
EW,ES models
BFC (Beat Frequency Control) Switch

· 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.
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.

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)
For two-channel input, slide this switch to the left. For four-channel input, slide this switch to the right.
Audio frequency range to be output
Very Low Frequency range Full range Low Frequency range to High Frequency range
Speaker Type
Subwoofer Full range Full range
Remarks
Connect a subwoofer. 4 Use if you want to cut the very low frequency range because it is not necessary for the speakers you are using.
