Here another add on suggestion:
Line6 could develop a in ear monitoring system (IEM) connected over Line6-Link to the Stagescape.
I found the Quadra wireless IEM in the net: http://www.lectrosonics.com/Wireless-Monitors/quadra.html
If you develop a transmiter with 4 channels in one box, connected over one cable to the mixer, that would be a very nice and easy solution.
Thank you for this recommendation. It is a good one and it definitely makes sense as part of the live sound environment. Recommendations like this can be submitted to our product feedback page here: http://line6.com/company/contact/productfeedback/
But feel free to add these suggestions on the forums.
