How to resolve miswiring problem on jvc steeo car


MIS WIRING" is displayed when there is a DC offset voltage detected at the speaker terminals ('+' and '-').

This is normally caused by connecting a '+' or '-' speaker wire to either GND or Vcc (+12V)

1. Collect cable not being used and make sure they are tapped off and reset

2. Remove a connected cable one at a time and press RESET

3. If after a cable removal and reset the error goes away, last cable removed was fault. Examine cable for short.

4. If you remove and reset all cables except for (RED, YELLOW, and BLACK) and you stilll have error, the short is internal of unit and requires service

Kenwood with dc offset


DC offset is most often caused by the bias level for the output transistors changing for some reason. This could just be that the control is dirty and needs to be cleaned and re-adjusted, or the biasing network has a problem, most likely the diode or transistor that is being used to set the reference. The diode or transistor is often mounted to the heatsink for thermal feedback, which allows the bias to change depending on how hot the output transistors are getting, There is no mention as to how high the DC offset is. The usual range for DC offset adjustment is less than +/- 1 volt. If your offset is higher than this, there usually is a problem with the bias circuit that needs to be repaired. If it is MUCH higher, then one of you output transistors or driver transistors is most likely defective.

My kenwood ddx616 indash keep showin DC OFFSET ERROER?


You could have a speaker wire or speaker tensile (flex) lead that is shorting to ground, on a floating ground BTL head unit (all that claim 18-25 watts RMS per channel) all 8 speaker wires are always floating at about half of the supply voltage, IE if the voltage is 14.4 with the engine running the speaker wires will all measure about 7 volts to ground.

The flex leads are the wires on a speaker that go from the terminals to the cone.

DC Offsets on output - protection don't allowd to switch on


you don't want to do this( bypass the protection0
that d.c. output will burn the coils in your speakers with out making a sound!! you have a biasing problem
or like you said a d.c. offset problem it is best to work on this problem with out a load on the amp, this will allow you to trace back where the trouble is starting at. caps will cause this sort of problem but leaky transistors can also do this, even diodes.
this will require an experienced trouble-shooter.

What does the offset light mean on sony xplod amp


THIS IS "DC OFFSET". MOST AMPLIFIER PROTECTION CIRCUITS REACT TO THIS CONDITION BY SHUTTING THE AMPLIFIER DOWN. THIS IS A CONDITION, NORMALLY BROUGHT ON BY SHORTED OUTPUT TRANSISTORS, THAT ARE TRYING TO PASS THE POWER SUPPLY DC CURRENT TO THE SPEAKERS, WHICH IN A MATTER OF SECONDS, WOULD BURN THE VOICE-COILS IN THE SPEAKERS. MOST TIMES THIS WOULD BE CHARACTERIZED AS HOOKING THE SPEAKERS UP AND OBSERVING THEM SIMPLY POKING OUT OR IN CONSTANTLY WHICH CREATES MUCH EXCESS HEAT. THIS IS WHY THE AMPLIFIER WILL SHUT DOWN TO PROTECT THE SPEAKERS. YOU CAN TRY TO DISCONNECT THE SPEAKERS AND THE RCA INPUTS THEN POWER THE AMPLIFIER UP. IF THE DC OFFSET LIGHT STILL ILLUMINATES, THEN YOU WILL HAVE TO HAVE THIS UNIT REPAIRED. ONCE REPAIRED, BEFORE REINSTALLING IT, MAKE SURE TO CHECK YOUR SPEAKERS FOR DAMAGED VOICE-COILS, WHICH COULD HAVE BEEN THE PRIMARY CAUSE OF FAILURE. OK. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE....V

When the amplifier shows an offset fault, it's generally because there is DC voltage present on the speaker terminals. The amp has shut down to protect the speakers.
