sure to protect all cables and important equipment
such as fuel lines, brake lines and the electrical
wiring from damage.
• DO NOT allow amplifier to come into contact
with liquids due to, for example, the location
where the amplifier is installed. Electrical shock

Setting the Unit
Gain Control
If the sound level is too low, even when the volume of the car stereo used along
with this power amplifier is turned up, turn gain control clockwise. If the sound
distorts when the volume is turned up, turn the gain control counterclockwise.
• 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.
ENGLISH
LPF (Low-Pass-Filter) Cut Off Frequency Control
You can select a cut off frequency from 40 Hz to 240 Hz.
Power Indicator (Blue)
The power indicator lights when the power is switched on.
BFC (Beat Frequency Control) Switch
If you hear a beat while listening to an AM broadcast with your car stereo, change the BFC
switch using a small standard tip screwdriver.
Input Switch
It is possible to input from a car stereo external output or a car stereo speaker output. Switch
the input switch before turning on the power. Since switching the input switch while the
power is on can cause a loud noise to be emitted from the speakers, the power is turned off
by a protection function. When using an external output, slide the switch to the right (RCA).
For connection instructions, see the "Connection Diagram" section. When using a speaker
output, slide the switch to the left (SP). In this case, it is necessary to use the supplied speak-
er input wire with RCA pin cord. For details, see the "Using the Speaker Input" section.
Bass Boost Control
You can adjust a bass boost level from 0 dB to 12 dB.
For instruction of connecting the bass boost remote control to the amplifier, see the
"Connection Diagram" section.
