1 Power indicator
When the power is turned on, the Power indicator lights.
If the Power indicator does not light when the power is turned on, the
protection function may be activated. Check whether there is any indication
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 PHASE switch
When this switch is set "180°" (Reverse) the speaker output phase is reversed.
5 BASS BOOST LEVEL control
Sets the low frequency level to be compensated.
6 LPF(Low-Pass Filter) FREQUENCY control
This control adjusts the frequency band output from this unit.
7 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.
Troubleshooting Guide
What might appear to be a malfunction in your unit may just be the result
of slight misoperation or miswiring. Before calling service, first check the
following table for possible problems.
No sound. (Blown fuse.)
✔
Input (or output) cables are disconnected.
☞
Connect the input (or output) cables.
✔
Protection circuit may be activated.
☞
Check connections by referring to <Protection function>.
✔
Volume is too high.
☞
Replace the fuse and use lower volume.
✔
The speaker cord is shorted.
☞
After check the speaker cord and fixing the cause of the short, replace the
fuse.
The output level is too small (or too large).
✔
The input sensitivity adjusting control is not set to the correct position.
☞
Adjust the control correctly referring to <Controls>.
The sound quality is bad. (The sound is distorted.)
The speakers wire are connected with wrong 9 / · polarity.
✔
Connect them properly checking the 9 / · of the terminals and wires
