Receiver shows overload because the volume was turned up all the way thank you gina

Your Denon receiver may be going into overload, which comes from playing it too long, and too loud. Try reducing the volume to 1/2 your normal level. If you still have issues or questions, please visit my website at audioserviceclinic.com. Thank you.

This is a fault on the D/A digital / Analogue converter , The volume control being analogue is not processing the data in the cicuit and so there is no change in the level. This can be a fault in the IC - the D/A convertor IC which is not giving any response with the turn of the potentiometer. So check this within the amplifier ONLY if you are able to trace the circuit and replace the IC connected to the potentiometer.

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.

Overloads can be from excessive periods of high output 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 hands-on tech.

OVERLOAD indicator
This lights when an analog signal is too strong (the
SIGNAL SELECT needs to be on ANALOG). It
indicates the sound is distorting and the signal
should be reduced.

Hi Mobius,

Two things cause the overload warning.

• High Volume
• A short in one of the speakers.

More than likely, it's not a problem with the receiver. The fastest way to tell is to disconnect all speakers at the back of the receiver and turn it on. If it does not shut down, your receiver is ok and is just protecting itself from damage. If it stays on, check all your wiring, what it sounds like is that you have one or two braids of wire touching the other terminal. Not enough to cause a "short" at turn on, however, when you turn up the volume the resistance increases and creates a short, thus "overload" shows on the receiver. Hope this helps. If you need more help troubleshooting, post a comment and I can help more.

u can measure the speakers impedance, if is ok. I think this can be a problem, when is speakers with 4ohm conected.

possible short across speaker wires somewhere or even inside speaker

Firstly check all your speaker wiring. Any damage can cause a short which will overload the system. You might not notice it, due to the fact that when you have the system on loud, vibrations move the wires on the cabinets or elsewhere. So make certain there are no loose wires near the speakers terminals into each one. If all that is good go to the next check.
Check If the amp is getting VERY hot when the overload occurs, then it might have a faulty part(s) on it. This might have occurred if you have been using speakers that never did match the amps requirements in the first place.
