The acoustic properties of vehicle compartment tend to cause oscillation due to 

resonance or unclearness of sound due to standing waves at certain frequencies.

The band reject filter can solve the problems of resonance or unclear sound 

with minimum influence on the sound quality because it eliminates only the 

frequencies causing resonance or standing waves.

  Adjustment method:

The band reject filter cuts only the limited frequencies to minimize influence 

on the sound quality. Therefore, its effect cannot be obtained unless the 

cutoff frequencies are set accurately to the frequencies causing resonance 

and standing waves. The band reject filter can be adjusted according to what 

you feel through your ears, but we recommend the use of a signal generator 

or a spectrum analyzer with a fine frequency measurement capability for the 

adjustment.

• Adjustment using a signal generator:

Output a sine wave, vary its frequency to find the frequencies at which 

the vehicle compartment resonates or volume increases (standing waves 

occur), and set the B.R.F. FREQUENCY control to the position with which the 

resonance and standing waves disappear.

• Adjustment using a spectrum analyzer:

Output white noise (sound in which all frequencies are at a certain level), 

find the peak frequency observed on the spectrum analyzer, and set the 

B.R.F. FREQUENCY control to the position with which the peak observed on 

the spectrum analyzer disappears.

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.

PROBLEM

POSSIBLE CAUSE

SOLUTION

No sound.

(Blown fuse.)

•  Input (or output) cables are disconnected.

•  Protection circuit may be activated.

•  Volume is too high.

•  The speaker cord is shorted.

•  Connect the input (or output) cables.

•  Check connections by referring to "Protection function".

•  Replace the fuse and use lower volume.

•  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 

+

 /

-

polarity.

•  A speaker wire is pinched by a screw in the car body.

•  The switches may be set improperly.

•  Connect them properly checking the 

+

 / 

-

 of the terminals 

and wires well.

•  Connect the speaker wire again so that it is not pinched by 

anything.

•  Set switches properly by referring to "Controls".

The sound does not change 

even when you have changed 

it with the Amplifier Control.

•  The AMP CONT has been turned "OFF".

•  Turn the AMP CONT "ON".

The set value cannot be 

changed by the Amplifier 

Control of the unit.

•  The AMP Control of the Center Unit is being used.

•  Release the AMP Control mode of the Center Unit.

The Amplifier Control cannot 

be operated from the Center 

Unit.

•  An incorrect ID number is used for the Master amplifier.

•  The ID number of the amplifier has been changed.

•  Always set the ID number of the Master amplifier to "0".

•  After you have changed the ID number of an amplifier, turn Off 

the POWER switch of the Center Unit first, then turn it On again.
