    Same thing, only happens when being fed a dolby digital signal. Other sources such as interntal FM tuner and 2 Channel audio work fine. Just happened while watching a movie.

    I had the same problem with my technics sa-ex800, when I had both a and b speakers on I would try and go to pro-logic sound. I would get an error message. ( this was because I had the b set of speakers still on. I did not have a middle or surround speakers hooked up. the unit would give me the same comment yours did. The only way I could get rid of it was to unplug it for a long period of time.

    I have the same problem - just happened today. I had plugged in my Ipod, and noticed the sound was very low - i had it on max sound, and could only just hear it. Then it switched itself off and came up with the error message - OVERLOAD

Sounds to me like a thermal shutdown. If it's no longer under warrenty, try opening the housing and spraying the inside with compressed air to free up any dust. Dust acts as an insulator and doesn't allow the heat to dissipate.

Beyond that, I'm not sure what else could be done without a service manual.

I have a pioneer vsx 07 11 and it says amplifier error


You see, the error message is coming from the power protection circuit which is constantly monitoring current being drawn from the receiver power supply. When the current exceeds the trip level it shuts down and give the error message.


power amplifiers has been shorted and the output transistors (one or more) have gone into breakdown and causing the excessive current drain. This will happen even though the speakers may not be connected to the amp outputs.

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 pioneer amp vsx d508 reads overload.what to do?


Sounds like a bad amplifier IC.
Unhook all speakers at the back of your pioneer. turn it on and turn down the volume. If it's no longer in overload you have a bad speaker or speaker wires touching somewhere.
If its still in overload it's prlobley a amp IC and will cost between $25-$60 just for the part if you can replace it yourself.

Problem with pioneer vsx-916 av receiver


Be sure you have proper impedance with both sets connected. Some units have a selector switch in the back of the receiver to set the proper bias. ...accordianman

The best way to do this (if you haven't done this already) is to enable the Dynamic Range Control. This neat little setting makes the difference between loud and soft to be not so much, making soft sounds (like talking in your case) louder and something like explosions not so loud. This is also called Midnight Mode on some receivers. To enable this setting, grab your remote and turn the receiver on. Press the "Receiver" button, then hit the left arrow on the remote until you see something along the lines of "Dynamic range control" pop up on the LCD (should be the 8th setting). You probably want to set this to "Max", but you can also select "Mid" if you find that Max does too much.

If this still does not work, you can bump up the relative volume of the center channel a bit (or a lot of bit). Hit the "Standard" button on your remote, then "Test Tone" until "C" or "Center" comes up on the LCD. Then hit the "Level +" button a few times, making the center channel a little louder. Listen to it a while and adjust it to your liking.

The combination of these two settings should get you where you want to be. By the way, do a search on your favorite search engine for something like "manual Pioneer VSX-D512" and you should be able to download a manual from somewhere (it looks like Pioneer no longer hosts the manual on their site). Hope this helps!

All you have to do is connect the coaxial out from pc to any audio i/p at the back of vsx d512.but ensure you select the right channel to play the audio ( eg. tape i/p select tape at front control, aux i/p select the aux at front control )
