A very good unit
I ordered the Behringer Xenyx X2222USB and Audeo Interface with Effects from Sweetwater. Thanks Alan for the help with it. I found this small mixer to exceed my expectations. I haven't read the manual through yet, so I'm optimistic about what I may discover when I do. I play organ in a smallish church and work with a praise team of five people. I believe that there is room to grow with this unit and I plan to get more mics in the future. It has worked with all of the gear I've connected to it, with aplomb. The price is right, and the abilities of the unit are good. My personal head worn mic has plenty of volume without feeding back. A better mic will likely work even better. The effects are very believable and useful especially the reverb.
I recommend this unit for anyone with a small group and limited performance space and a limited budget.
