If the display shows overload, you are playing it too loud, or have too many speakers connected. Overload is a protection method used to shut down the unit, before it's damaged.

There should be a overload to its main power supply regulator section cirlcuit. Actually this section is working well, but when it supplies secondary voltages to the other section circuits, it detects an overload with any other of it, and shuts itself OFF, to prevent further damages, goes to standby mode, and then to protect stage.

NAD M3 power light turns red immediately and PROTECT message displays. Amp keeps functioning but volume control doesn't work up or down.


Hello
Check the connection to speaker with this amp, for any short or any other fault. disconnect the outputs, ie, speakers from the amp, and switch it On, and see the protect display comes or not. If it comes, the fault is internal and the set need service.
Your M3 dual Mono integrated amp, is of high output power and its outputs are protected against any overload or short circuit. If the system detect any among this condition specified above, it will show protect mode display.
Never load this amp, as protection display is there, as it may damage the speaker or its internal power amplifier section circuits, may cause more money to get it repaired. OK.

I dont know how to delete a protected picture off my canon power shot a470 camera. Can you help?


You have to unprotect it first. It's a bit confusing because the menu item probably only says "Protect..." but it also takes care of unprotecting too. Go into the menu for "Protect..." and navigate to the protected one. Whatever button you press to switch the protected status (it's the SET button on my Canon) you can use it to turn the protection off as well. When you exit the protection mode, you can delete it.

The SONY STR DE595 goes into "protect" mode upon turning it on.I recut all speaker wires & vacuumed the receiver ...unplugged,differenet outlets...etc.Any advice?


The protect thing is to do with an overload. It's more than likely that something in the main amp section has failed (perhaps a transistor on the big heat sink). The cause often speaker wiring touching together. You should look carefully at the this section for damage or burning. If you have a ohm meter you can test the transistors. If you place the probes on the terminals of each transistor and you get a responce like you had touch the probes together, you have located the source of the overload.

My home stereo amp goes into protection mode after about 2 min of being powered on do you know why/


The chances are that it does so due to a faulty part. Often these protection circuits are to detect an overload in either the power supply or the main amp section. Sometimes it's due to a speaker wiring problem, cables that are not suppose to touch - touching. They sometimes reset when either the overload has gone or the wire touching has been corrected. This sounds like it might be too late, and now a semi-conductor (on the heatsink) is acting like a piece of wire! Tripping the circuit. If you get power to the unit (lights etc) then it's probably not the power supply section to blame.

The protection lite comes on when amp is given powerand sometimes it does not come on but it is still not getting any sound its not my wires they all work for any other amp tell me is my amp fried


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. Sounds like you are overloading the amp. Please check speakers impedance. .A thumbs up would be greatly appreciated if this answer is helpful to you

Overload message in technics model SA- EX400P-K I have an older Technics system. It has worked great for years but now I get overload whenever I turn it on. Have changed speaker wires but no use. Any...


The overload message is the old version of "protect" mode. This means that a problem has been detected in the output amp section and that section is shutdown to prevent further damage. Your unit uses amp-pacs. One or more are bad. These are marked RSN3305P and cost about $66 each.
