I've been using this for close to a year now for shows and practice. Once you get your mix dialed in Its bearable. One of the necessary evil musical investments I've had to make.
Solid IEM system. Good sound quality, no latency, and solid construction. Mixmode works great for blending my signal with my band's mix. We operate two of these systems, both in the G20 range with no crosstalk issues.
My gripes are: 1. Receiver antenna is not replaceable. While it's not exactly flimsy, breaking the antenna ruins a $500 receiver. I wish the replaceable antenna from the P9RA had been used on this. 2. Rechargeable battery system is prohibitively expensive. Battery packs are $114 USD each and don't even come with a charger, which is another $80 USD for a basic model. Unlike the GLX wireless system, the batteries can't be charged in the belt pack. I opted to use Panasonic Eneloop Pro rechargeable AA batteries, which work very well at a fraction of the cost.
