Troubleshooting guideWhat 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 SOLUTIONNo sound.(No sound from one side.)(Blown fuse.)
• Input(oroutput)cablesaredisconnected.• Protectioncircuitmaybeactivated.
• Volumeistoohigh.• Thespeakercordisshorted.
• Connecttheinput(oroutput)cables.• Checkconnectionsbyreferringto
<Protectionfunction>.• Replacethefuseanduselowervolume.• Aftercheckthespeakercordandfixingthe
causeoftheshort,replacethefuse.The output level is too small (or too large).
• Theinputsensitivityadjustingcontrolisnotsettothecorrectposition.
• Adjustthecontrolcorrectlyreferringto<Controls>.
The sound quality is bad.(The sound is distorted.)
• Thespeakerswireareconnectedwithwrongª/· polarity.
• Aspeakerwireispinchedbyascrewinthecarbody.

The unit is a 5-channel amplifier incorporating 2 stereo amplifiers and 1 monaural amplifier in a single body. The stereo amplifier on one side is called amplifier A, while the one on the other side is amplifier B. The monaural amplifier is called the amplifier SUB. This unit is compatible with a large variety of systems by combining the switches and functions described in the following.1 Fuse (40 A x 2)
