A diode/rectifer or voltage stabliser, or leaky capacitor in the power supply.
Also the main transistors in the power amp or if it has an output IC - that!
If you can in anyway disconnect the power supply section from the amp circuit, you can isolate which part is faulty. For if it blows when disconnected from the power amp, you know it's just the power supply that's gone. And if it does not blow - then it's the amp!
You could check the 115/230 switch. If you are getting power to the unit no fuse or circuit breakers tripped, and you have 8 ohm speakers connected, and a signal in you should get a signal out. Level controls should be up. If all of those things are true, then the amp is broke and needs an electronic technician to repair it.
First of all the EXA-3940 is rated at 350watts per channel in to 8 ohms. The 1400 watts is bridged into a 4 ohm load. Second, the speakers can handle 1000Wats peak with an average of 600 continuous (i'm guessing). That tells me that the amp is underpowered for the speakers. The sensitivity of the amp is such that the mixer is overdriving the input stage. That is what is causing the clipping. If you are looking for more volume, you are probably better off purchasing another amp and running them in bridge mode, 1 per speaker cab. Be careful though, not to overdrive the speaker cabinets either.
please confirm from your speakers cables in good condition and from your speakers.make maintenance to your amp by air blower-clean air filter-keep good ventilation around.after cleaning and good ventilation make test with any media while you are connecting one speaker only and then connect the other one.
Trying to use the computer controlled JVC AM/FM Tuner Model FX-333.
I am attempting to use the pre-set stations desired for listening pleasure, but I have not been successful. Can you help me?
The FX-333 Tuner is linked to the AX-R441 Amp.
