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.
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 connection instructions, see the “Connection Diagram” section. When using a speaker output, slide the switch to the right. In this case, it is necessary to use the supplied speaker input wire with RCA pin cord. For details, see the “Using the Speaker Input” section.
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.
