Hey guys. I just bought a new Gemsound EXA-3955 amplifier and first time out of the box i plug it in and turn it on, and it works great. I dont turn it up too loud or change any wiring. Then I turn it on to show my friend the next day and the right channel wont work, and all i hear on that side is a low hum. Can anyone help me fix this problem. I checked all the wires and connections and they are all fine. Please help!
Lol i bought a Gemsound EXA-3955 cheap then the right fan stoped working i replased it with a computer fan before i let it burn up it payed for it self and im still tacking it around with 2 18" folded horn im 18 years old this is not rocket science
You sure you didnt flip the bridge switch on the back? its the tiny little black switch under the bridge output plug, if you have it set to "bridged mode" any input sent into the right channel produces only a hum, only left channel input works.

I Think that something like a transistor is getting hot and then shutting down. Exploring inside might solve the problem of what's getting really hot. You could even get some Servisol Freeze Spray, and wait for it to go off then spray it on the suspected part. That will cool it down and it should start up again. If it does come on, that part will have to be replaced.
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.
where is your location my friend? did you check your amps power input requirements. you may be having the wrong voltage supplied to your amp. unless there is a defect on the amp unit you bought otherwise check your voltage settings first
