Did a gig last night where the sound tech has the X32 desk, and 4 of these IEM controllers. Cringe - I was impressed. Good sound quality, and the user interface was good. Didn't take long to pull a reasonable mix. I was considering getting the controllers and the rack converter to set up for the band regardless of what desk we get at a gig - just using a TRS snake to take direct outs off the channels straight into the converter. Just wanted to share my experience.
