Amp switches off at about -10db volume level

The amp switches off at higher volume levels. When I turm it back on, the display reads - " check speaker cables" or something similar. The cable I have used is Monster variety maybe 12 gage even for the center and rears. All speakers are 8 Ohms. All cable lengths are matched for fronts and rears. Thought it was a heat issue - fitted a fan to blow air from top and out bottom - made no difference - got any ideas how to stop this happening ??

Re: Amp switches off at about -10db volume level

Sun Prairie here again. I finally solved my own problem, although I never figured out exactly what was causing it. If I keep the volume setting low on the receiver everything is OK. I can still raise the volume at the wall speaker switches without shutting the system down and triggering the Check Speaker Wires message.

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.

Hi Strange problem with Marantz pm7001 When ever I turn the volume upto around 1/3 and 1/2 of the way, the amp cuts out and reset it self down to minimum volume. It seems like the amp ins't enough power...

What's probably happening is that the amplifier is shutting down or cutting back the volume as protection from damage. You may have a partial short in the speaker wiring that is not a problem at lower levels, but at higher ones causes the amp to see too low a load. There may a problem with a speaker or crossover component that is breaking down at higher volumes. Or something in the amp's output stage is unable to handle the load.

Test the system with a known good speaker system and length of wire and see if the trouble continues. If it does, you'll know it's the amplifier that needs to be checked. If the test speakers can reach normal volume, you can start checking the wiring and other speakers for the source of the trouble.

Did you try changing the front & center speakers to a higher level as well as setting the surrounds to a lower level? Are all speakers using the same wire gage?

It says protector mode what does that mean

If PROTECT , PROTECTOR or a P is flashing in the display of the A/V receiver, there may be an incorrect connection or an improper setting. Try following these steps to resolve this issue:

NOTE: Because each of these steps represents a possible solution to this issue, check the A/V receiver status after completing each step.
  1. Check the speakers and speaker wires for proper connections.
  2. Reduce the volume level. IMPORTANT: If the A/V receiver is used at maximum volume level, it may enter the PROTECT mode. Maximum volume listening will cause the A/V receiver to run very hot and may drain the output capacitors.
  3. If applicable to your model, disable the surround sound option if both the A and B speakers are being used simultaneously.
  4. Ensure the top of the A/V receiver has proper ventilation to keep it from overheating.
  5. If the message only occurs when using a DVD player, the sampling frequency may be set too high. IMPORTANT: Some A/V receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the owners manual for specific information.
  6. Unplug the AC power cord for approximately 1 to 2 hours to reset the output transformers.
If the issue is still unresolved, service may be required.

I have Bose speakers hooked up with JVC RX668V and the rear speakers aren't loud enough! What can I do to get more volume?

What models of speakers all around? Certain combinations of speaker efficiencies won't be within this unit's capabilities to compensate the volume.

Starting on Page 17 they discuss how you can adjust the Digital Acoustic Processor (DAP) mode to modify the levels of the rear speakers -10dB to + 10dB.

Starting on Page 20 they have similar settings for 5.1 discrete analog inputs.

It turns off with an error to Check Speaker wires. It's done this in the past, usual if I push the volume too it's threshold. It would always bounce back. Now it shuts down at just about it's mid-peak...

Did the fact that it was responding negatively to the loud volume not suggest it might be a bad idea to keep doing it?

The threshold on the volume knob is NOT where normal undistorted listening levels are found. Given a normal level of input you could be pushing your amp so hard that it clips or distorts and kills your speakers.

Do what it asks: check the speaker wires for shorts. Or disconnect the speakers and pray it comes back to life, then isolate the shorted (dead) speaker.
