The Omni has 4 inputs. 2 XLR/1/4" on the front and 2 1/4" on the back. The front inputs have volume controls/preamps and phantom power. The rears are line level (I assume). I use the rears as a stereo input from the POD and the fronts for mics.
If you want more than four inputs we'll have to wait for someone else to post.
