Controls
1 Power indicator

of trouble. Refer to <Protection function> (page 3).
2 Illumination
3 ISF (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.
4 BASS BOOST LEVEL control
Sets the low frequency level to be compensated.
5 LPF(Low-Pass Filter) FREQUENCY control
This control adjusts the frequency band output from this unit.
6 INPUT 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.
