Gain Control
The power indicator lights when the power is switched on.
Power Indicator
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. · If you hear too much noise when using the speaker input terminals, turn the gain control 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)
Input Select Switch
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
-- 40 to 120 Hz Full range 40 to 120 Hz --
Speaker Type
Subwoofer Full range Full range
Remarks
Connect a subwoofer.
Cut Off Frequency Control
If the LPF/HPF select switch is set to LPF or HPF, you can select a cut off frequency from 40 to 120 Hz.
Use if you want to cut the very low frequency range because it is not necessary for the speakers you are using.

Speaker terminal
System remote control wire (sold separately) Connect the male terminal of this wire to the system remote control terminal of the car stereo (SYSTEM REMOTE CONTROL). The female terminal can be connected to the auto-antenna relay control terminal. If the car stereo does not have a system remote control terminal, connect the male terminal to the power terminal through the ignition switch.

Note:
· Specifications and the design are subject to possible modification without notice due to improvements.
*Average current drawn
· The average current drawn is nearly the maximum current drawn by this unit when an audio signal is input. Use this value when working out total current drawn by multiple power amplifiers.
