Re: 4200

Lets try to narrow down your trouble here... you are using the amp with all 7channels working at -23 right? how long wil it run at -23 level? can you try running it a t stereo mode only using main 2 channels and see if it will also trip at the same level. if it doesn't, try trurning off then the main speakers and run only the remaining sets of speakers under the same level. observe again. did it trip? also you can try sending audio to left chanlle only then right channel only. see if it also trips.

if both ways it did not trip at -23 when you redcued the loads, it may not be really overload but overheating. does this model has a built in cooling system? Im not sure about this brand/model but can you give me an idea what year mnodel it is? it is 7 channels so it may be having its own DSP.

Re: 4200

Amp has 70 watts x 5 . speakers can handle up to 100 watts per speaker , so it is not overload. and -23 is not loud as the system can handle up to + 16 . protection mode just kicks in for no apparent reason. danny

Re: 4200

Are you using a right load for the amplifier. what the rated output power of your amplifier. and know the output of your speakers.

well sometimes it protects you from being deaf.. for maybe its too loud so it goes to protection mode. dont know if -23 could make a person deaf.

well I hope I helped you with my solutions.. ^.^ please dont hesitate to respond us..

My Harmon kardon is stuck in protect mode

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you. Worth fixing.

Mamantz amp is on stand by mode , pls advise

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.

The OVERLOAD on my Marantz PM 44-SE is tripping out even at very low volume setting - using any of the inputs with either speakers connected or disconnected. I can even hear it tripping when no inputs or...

Overload is another form of protect mode. See the link below for an explanation of protect. Also, in your specific case, the problem is definately internal to the amp rather than an external cause. Expect a parts cost in the $40 range. Feel free to post additional questions.

When I turn my amp on it stays on for one second and then goes into standby mode. I have unpluged it for five minutes and turned on again and no change.

It is possible that the amplifier is going into the Protect Mode as there are some errors in the board. The prime suspect can be the output section of the amplifer as it might be short therby comsuming higher current for the protection to activate.
Remvoe speakers to test, if not checck the output stages, disconnect power to confirm.

Unit is in protection mode

Disconnect all speakers from it, then turn it back on. If the unit is OK, it should come out of protection. Turn it off, then reconnect one speaker and power on, repeat until it goes into protection, then you know where the problem is. Now disconnect the speaker wire that caused the problem but this time at the speaker. Make sure your wires do not touch, then turn it back on. If it stays on, it's a speaker problem, if it shuts off it's a wire problem. If you still need more help, post a comment and I will help some more. Hope this helps

Eltax avr-200 no sound

Eltax AVR-200 will start up in protection mode if the amplifer went into protection mode due to high volume before it was turned OFF and it will start at the same volume level as it had before power OFF.

To correct this you must shift to another input without signal, then turn the volume down before it goes into protection mode again.
