Jimmylennon, I went through 2-SX4882 Eurodesk. The first I spilled some liquid in it or water, spend days taking it apart and it is heavy and not easy to take apart. I gave up fixing it (became noisy) and bought a new one. After a year with the new one I had trouble with the sound dropping out on the op-amps on 1-2 channels, using channels 1-24, I switched to channels 25-48 and used those until I sold it. It could be the power switch, I always used a remote control AC power strip or control to turn it on because it was hard reaching to the back the way my desk is set up. Try changing the line AC cord, it is standard. The Eurodesk made before the 4882, I think it was the 8080? Same schematic but different op-amps, it had a external power supply box, the power supply on the 4882 is inside, and a pain to get to, there is no user parts, or standard IC components to replace, it's wired to main board if I remember and no disconnect plugs. It's a gamble, but buy a A/C power remote, or power strip. Plug the 4882 in it, turn on the remote A/C strip or controller, cycle the power switch on the 4882 until it comes on, if it does do not touch that power switch on the 4882, use the remote from now. It could be the power supply there are no circuit breakers in the 4882 and fuses only work once. I got the Westek RFK306LC on Amazon, and connected it to my power strip. It says outdoors, but works fine indoors to and has a great current rating. It cost less than $15. Note if it is the power switch, the unit is a pain to take apart and jump out. Good luck. I know there are a lot of people that say Behringer makes crappy products, but every company has a return and repair department. As far as mixers, I built a few for my own and a few small studios since the late 60's. You use what you got and get the best sound you can with it. Once the final mix, mastering is done and even before, with a good engineers you can't say what mixers were used or how much they cost, used Windows or Mac. But back in the day you could see the difference between Betamax and VHS. You walked into a studio and you used what they had, if you're good you can work on anything and get the best out of what's there. It's like a mechanic in a auto shop, some can fix everything and others can only work on what they were trained on or need aid with a computer. It was much easier when I had one compressor with two knobs, than to think today which one would sound better with this. I'd be there all day if tried everyone. Again I hope it's the A/C power line cord, and then maybe the switch. Since the model is discontinued I doubt if you could get the parts, and getting it fixed because it is so heavy and hard to take apart may not be possible.
