Well, I took one to the job tonight and set it up. It sounded very good to me. I couldn't hear any noise at all, just music.
I just ran it flat, and used effects and mix from the Audya.
After the night was over, I tried "shooting" the room with the RAC thing, and it made it sound tinny and metallic. I probably did it wrong. Then I set it to the "Natural" preset and it sounded very good, but I couldn't say that it was better than it did before, just different.
I will fool with it some more when I get a chance. I need to re-read the manual about the white noise and all that. Back to the porcelain library.
It's a good little mixer though, especially since they seem to be dumping them at really low prices.
