Question about Samson SX1200 Amplifier
SOURCE: samson sx1800 power surge
Manufacturers install protection devices in their audio systems that are there for that purpose, any loud 'thump' or 'crack' trips the protection device so the loud speaker wont be burnt out. Speakers are expensive so the manufacturer does his best to allow you to listen to very loud sound and yet provided protection in case you exceed the sound rating of the output protection device.
In your case it sounds like the protection device has done its job but has not reset, to allow more listening...
Check the operational manual that came with the amp system to see if there are re-set instructions available to you....
If you dont have the reset detail, then phone/e-mail the manufacturer to obtain the reset information...
If there is no resetting you can do as a consumer then it should be no problem for a service shop to do the reset for you...
It may be a simple internal fuse that has blown but if its not accessible from the outside then I dont suggest you go inside and make changes unless you are skilled and trained in electronic servicing...
Cheers for now YUBEUT

SOURCE: Gem Sound clipping problem
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.
