Been using a Rolls 351 and want to take the next step to a full wireless. Looking at the MIPRO 808, Shure PSM200 and AT M2, all appear to do basically the same thing. Any opinions on these? The MIPRO seems to out perform the others, but virtually no reviews anywhere except one guy that pushes them pretty hard. All within $50 of each other. I want to be able to mix a aux out from the board with my bass signal. With the Rolls, I have been using the effects out to the Rolls, aux out from the board, works OK. Question - will any of these accept either the effects out or DI off the back of the amp for the bass input? I can run the DI to the wireless then plug the board into the pass through on the wireless unit. Now that I think about it, I am going to try this with the Rolls. Any help or advice is appreciated!
