Pioneer amplifier vsx-d512 overload message


This indicates the audio output stage in the receiver is loading down and triggering the overload protection circuit to kick in. Check the speaker wires for shorts, if okay! you will need a professional to assess the cost for repair.

My amplifier when i put it at -50 and more it write overload .....pionner vsx-d511


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Hello, Problem is that after a few seconds the display shows "overload. " integrated circuits seem to be good, and I say this because I measured the voltage on each output amplifiers, and I have...


ALL the IC's are ok?

You'd measure 0 vdc if it was turned off, too, so that doesn't prove much.

VSX-859 RDS turns off


This is pretty close to the same Operating Manual.

This is the service manual, for what it's worth.

Power overload


That is a good thing, your receiver is going into "protect mode" that means the receiver is shutting down to keep from damaging delicate internal circuitry, it is sensing a speaker bottoming out or some other electrical "short" that could be damaging!
Also could be from over driveing the amp and then it starts to overheat thus going into "protect mode".
If your speakers are "clipping or distorting" turn it down, you are going to ruin your amp. Good luck !

Woofer problem


If I am not mistaking here, you need a self powered subwoofer to use with this unit. Those are line driven outputs for this unit. Make sure there is a wall plug on the sub that is plugged in. Good Luck
