3ISF (infrasonic filter) switch

Ultralow frequencies that cannot be reproduced even by a subwoofer speaker do not become sound but become unnecessary oscillations, which affect the sound by causing distortion, etc. Setting this switch to "15 Hz" or "25 Hz" cuts the frequencies below the respective frequency.

This improves the reproduction performance of the speakers by eliminating unnecessary oscillations which will not become sound.

4BASS BOOST LEVEL control

Sets the low frequency level to be compensated.

5LPF(Low-Pass Filter) FREQUENCY control

This control adjusts the frequency band output from this unit.

6INPUT SENSITIVITY control

Set this control according to the pre-output level of the center unit connected with this unit, or to the maximum power output of the genuine-accessory car stereo.
