For me, the Eon One has been just an outstanding PA system. It's been able to take the place of our two Bose Compacts, which I sold to a friend.
And, I like the way the Eon One mixer is laid out. I don't like as much the way the Eon One Pro mixer is laid out.
I've never had any input issues with the Eon One as others have stated.
Now I could get interested in an Eon One that is 3/4 the size and weight of the present Eon One, provided it sounded as good.
