Adjusting the RCA input level control will help match the
output of the car stereo to the Pioneer amplifier. If the

turned up, turn this control clockwise. If there is distortion
when the volume of the car stereo is turned up, turn this
control counterclockwise.
• Adjust control O with the supplied adjustment screwdriver.
Keep the screwdriver if you need to readjust the controls later.
BFC (Beat Frequency Control) switch
Note:
Beating is the combining of two or more frequencies to produce
sum and difference frequencies called beats.
If beating is heard when listening to AM stations on you car
radio, change the position of the BFC switch on the bottom
of the amplifier with a small flat-bfaded screwdriver.

Compulsory fan cooling system
This is a high-power amplifier, so it produces a lot of heat.
To keep it cool, it has fan cooling.
• When the power of the car stereo is turned on, the compulsory
cooling fan of this power amplifier works automatically and
cools inside of this amplifier.
• Install the amplifier so there is enough space front and back to
allow the fan cooling to work properly. If the front or back side is
covered, the amplifier may malfunction or fail.
