I'm pretty sure every wireless vendor out there "thinks" about doing wireless
digital IEM. The problem is to get latency down to acceptable level - a problem
you virtually don't have with analog wireless systems. This is largely why
the wireless digital IEM market is... "underdeveloped". :-)
I've read somewhere about the L6 stuff having a latency in the range of 2,5ms.
Works for me in guitar usage, but is already a lot when combined with digital
mixers etc... you're already in the latency range where you get ugly comb
filtering effects (combination of body sound and IEM headphone sound for
singers) or even get problems playing tight because IEM is too delayed.
Think of 2,5ms mic/guitar wireless, plus 2-3ms for digital mixer, plus
2,5ms for wireless IEM... and you are already on your way out of the worst
comb filtering area but getting into noticable delay territory.
Looking at the industry, it seems that "fixing" the latency problem of digital
wireless systems is non-trivial.
I for one would certainly love to see an affordable ultra low latency digital
wireless IEM system. And yes, it's almost christmas time again. :-)
