Setting the Unit
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 Hz to 120 Hz.
BFC (Beat Frequency Control)
Switch
BFC switch is on the bottom of the unit.
If you hear a beat while listening to an
MW/LW broadcast with your car stereo,
change the BFC switch using a small
standard tip screwdriver.
Terminal Cover
Before setting up the unit, unfasten the
screws with a 4 mm hexagonal wrench
(not supplied) and remove the terminal
cover.
Input Switch
It is possible to input from a car stereo
external output (subwoofer output) or a
car stereo speaker output. When using
an external output (subwoofer output),
slide the switch to the left. For connec-
tion instructions, see the “Connection
Diagram” section. When using a speak-
er output, slide the switch to the right. In
this case, it is necessary to use the sup-
plied speaker input wire with RCA pin
cord. For details, see the “Using the
Speaker Input” section.
