If the receiver works at low volume, but goes into OVERLOAD and shuts down at higher volume, it means you are player the unit too long and too loud. Try yo keep the volume down to a reasonable volume.

Rockola 481 max 2, mechanical overload light comes on, reset button resores play for a short time, what causes it?


Sometimes a motor is too slow because it's dirty and more current is needed to turn it, so everything ramps up and overloads.

The speakers on my flhtcu 2006 cut out if i toggle the speaker switch they come back on. I have replaced the speaker switch. with no effect.


This would seem to be a problem with your usage rather than your equipment, it would be advisable to turn the volume down to see if this will cause the problem to disappear. When an amplifier goes into overload , the common reset is to turn off the speakers. There could be a problem with one or all of the following, speakers or amplifier.

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.

Why the red light comes on when i turn the volume up


Hello
It is an overload indication. Check the wiring of the speakers. If speakers of very low impedence have connected to this amp, they will overload the amp, and its protection circuit will work. Anyway, the output impedence of the amp is now very low than specified. OK.

NAD C326BEE amp problem. Connected to recommended Wharfdale speakers and NAD CD player and previously working fine for a year. Now red light flashing on amp and no sound when system is turned on.


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.

Check for loose speaker connections at the speaker as a root cause for ntermittent shutdown.

Receiver shuts off as volume is turned up beyond


try connecting only 1 speaker at a time. try it on each of the binding posts (connection terminals), crank it up to locate which one of the speaker terminals is overloading the amplifier.

Then connect a different speaker to that terminal to see if it still overloads. This should determine if its the speaker that is overloading that particular terminal or if something is wrong with the amplifier.

Just for fun make sure that the cables you are using don't have any fraying and that none of the speaker binding posts have any loose strands of wire possibly grounding out to the chassis of the receiver.

I have a rockola mystic jukebox & one side of the speakers does not work, i would be greatful for any tips


Either a bad connection somewhere, or one channel in your amplifier is out.

Before you try anything else, switch the amp from 'stereo' to 'mono.' If the speakers come on, your amp is good and you simply have a bad connection somewhere between the amplifier and cartridge (thing that holds the stylus"needle"). Or, possible, but not probable, a bad cartridge.
For a quick fix, switch the amplifier to "mono" and then run all the speakers to the working channel.
In the meantime, if you're handy, try switching the speaker leads and such and see if you can isolate the problem.
