Setting the Unit

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.
Input Select Switch
For two-channel input, slide this switch
to the left. For four-channel input, slide
this switch to the right.
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.
Power Indicator
The power indicator lights when the
power is switched on.
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 Audio frequency range Speaker Remarks
Switch to be output Type
LPF (left) * — 40 to 120 Hz Subwoofer Connect a subwoofer.
OFF (center) Full range Full range
HPF (right) * 40 to 120 Hz — Full range Use if you want to cut the
very low frequency range*
because it is not necessary
for the speakers you are
using.
* See the "Cut Off Frequency Control" section.
