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 on the front of the
power amplifier clockwise. If the sound
distorts when the volume is turned up,
turn the gain control counter-clockwise.

• 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 con-
trol counter-clockwise.
