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 
control counter-clockwise.
Power Indicator
The power indicator lights when the
power is switched on.
BFC (Beat Frequency Control) Switch
(GM-X572/XR/EW, X572/XR/ES)
If you hear a beat while listening to an
MW/LW broadcast with your car stereo,
change the BFC switch using a small stan-
dard tip screwdriver.
