Played with Mixer
Despite the cold in my head and throat, I've had a chance to play around with my new Behringer UB1204 mixer and so far everything seems great with it. It turned out I didn't need any extra cables, I just needed to use my brain. It was a little different to set up than my Mackie but I pretty much have everything working the way I want it right now, I think.
Using my amateur hearing, I can detect no difference in quality of the mixer. The preamps sound a tiny bit different to my ear, but I can't really tell if that's a good or a bad thing. I'll probably have to use it a bit more to be able to make some sort of decision on that. I'm assuming that they're probably fine.
All in all, considering the price and quality of it so far, I'm very happy with the unit and I'd recommend it to anyone looking for a mixing board.
