Setting the Unit
<ENGLISH>
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-clockwise.
• 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.
