 Ground terminal

4

 Power control terminal

Controls the unit ON/OFF.

NOTE

Controls the unit power. Be sure to connect it with all the systems.

5

 Speaker output terminals

As this unit accepts speakers with a minimum impedance of 2 ohms, 
connect speakers with 2-ohms or higher impedance to these terminals.

2

CAUTION

The rated input of the speakers should be no less than the maximum output 
of the amplifier. Otherwise malfunction may result.

6

 BASS BOOST LEVEL control 

Sets the low frequency level to be compensated.

7

 LPF(Low-Pass Filter) FREQUENCY control

This control adjusts the frequency band output from this unit.

8

 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.

9

 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.
Use the diagram on the right as a guide.

NOTE

For the pre-output level or the maximum power output, refer to the 
<Specifications> in the instruction manual of the center unit.

•  Do not connect cables and leads to both RCA cable input jacks and 

the speaker level input terminals simultaneously, for this may cause 
malfunction or damage.

•  Connect the power control lead to a power supply which can be turned 

ON/OFF by the ignition key switch (ACC line). With this connection, shock 
noise may be generated when the power of the genuine-accessory car
