This is called "clipping" and is caused by the amp overcurrent circuitry, too low of impedence in speaker system, or insufficient power to amp

Jvc rx 5052 overload when volumes open


Could be....
  1. There's a short in your speaker wiring somewhere
  2. or a blown speaker
  3. or you are recycling the speakers from an old all-in-one system and they're too low Ohms
Check your speakers first. If they are less than 8 Ohms, or there's no label on them which gives the Impedance (in Ohms) then I'll lay money that they aren't suitable for the amp. Stop using them and get some proper 8 Ohm speakers.

Wiring shorts might be only a single strand of copper wire. But it's enough that at higher volumes it conducts enough current between the speaker terminals to trip the amp's protection mode.

Fix the problem. Go through your wiring. Check using a torch. If all looks good then it's a blown speaker.

Remove the speaker wires from the amp. Switch the amp on and turn the volume up full. The amp should stay on. Turn the volume down and switch off.

Now connect ONE speaker only. Try the amp on and volume up again. If it trips out then that's the faulty speaker. Repeat by adding one more speaker each time. When the amp trips, the last speaker added is the culpret.

Tip

My Amplifier shuts off at high volume


Basically, at low power the amplifier is not asking for a lot of power from the electrical system to power your sub woofer. For lack of a better term and probably the best way to explain it is. It uses up all the power in the wires leading to it at a high volume, and has to wait for more. Kind of like when someone squeezes a garden hose2_bing.gif when your trying to use it. That would be the high volume, starving the amplifier. The capacitor stores power in it to power the amp at high volume. 2 farads would probably be bulletproof on a single amplifier system, but 1 farad should work well enough. Or seek help from an expert on exactly what size capacitor you should use. If you find yourself saying: My amp cuts out.

If this assisted in solving your problem, please take the time to rate it, as I took the time to write it. Thank you.

If you've done all the simple stuff, then what's left is a problem with one of the output transistors. It needs the output transistor(s) replaced inside the unit. These directly drive the loudspeaker outputs on the receiver itself, and one or more of them being shorted (closed circuit), will trigger the error on the display of the receiver, and it will not go off until the problem is repaired. They are not user-replaceable as they are PCB mounted, and thermally coupled to a heatsink. In this case, the unit is in need of service.

When i try turn it on from standby the red protection light flashes 7 times? why and how do i fix it?


This is a common question on this site. Amps of all types have protection circuits to keep them from doing a self meltdown. Testing follows this logic. 1. Remove all speaker wires. 2. Keep the volume down - all the way. 3. Turn the unit on. 4. If it does not trip off, then there is a problem either in a speaker or the wiring. a. Reconnect one at a time until/unless it trips off b. That will tell you where to look further.
If it does trip off, then there is an internal circuit issue in the amp and probably requires professional help to fix.

My amp turns on but when i turn volume up it starts to thermal protect


Unless there is something wrong with the amplifier, there must be a shorted connection. Try doing the same with no speakers plugged in and see if the protection breaker trips. If it does not, then one of your speaker cables is shorted. Try installing the cables one by one, and test it, to see which one is at fault. Another remote possibility, is that one of the speakers is blown, or has a load lower than what the amp will accept.

My europower ep2500 amp the braker trips when I power it on


Hi,circiut braker trips only when the load on it is to much.
That is carry what is bigger than it watt, or can not carry too well. If you have another amp., you can put some load on that to reduce to braker always tripping off.

If that is the only amp. you have in what you are doing, just reduce the amp. volume to half(setting at 12 O CLOCK). it will work, but will not be too loud as before.

Take care.

Trips and switches off


Hello Fixya customer,

Thank you for your question.

The best way to fully isolate the fault is to disconnect all the speaker wires, and verify that there are no strands of wire shorting between the speaker terminals on the rear of the unit.

Turn the volume all the way down, full CCW, and if it goes into shut down with the STBY light blinking then there is a fault in one of the amplifier's.

Thank you for using Fixya, and if I can be of further assistance please ask.

Turn on, in a few seconds Flashing "OVERLOAD"


Overload  usually only appears if you have been using higher volumes for a period of time and this trips to protect your speakers and amplifier. Turning off your amplifier and leaving for a while and it automatically resets. other wise a would check your speaker cabling to see if any wires are  touching shorting out the circuit. Try removing you cables from your amp then turn on. If it turns on without Overload appearing the problem is between amp and speakers. Check your cables at both ends and while at it give them a clean then hook up everything ( Amp should be off) then turn on the amp and see if you get message. If you still get this message you could have  dry/ broken soldering on the inside and the amp is detecting a dc short in the system. This seem to a common thing these days. In which it will be a repair job.  Low impedance speakers or speakers that have a wide impedance swing when they are running at high volume can cause a amp to trip if it hasn't got enough current to drive low impedance speakers. Hope this has been of help.

When I turn the volume up even a little bit, the protect light comes on and stays on


Hiya,

Try disconnecting the speaker cables, then turn it up and see if it protects. If not, then connect one speaker at a time (on very low volume otherwise could pop the amp) and see if you can identify a faulty speaker/channel. Then try a known working speaker on the amp channel that is giving problems (to eliminate a fault with the amp). If the known working speaker also trips the amp, then it is that channel faulty. Hopefully you get away with a bad speaker wire though!!

Best of luck
