Quite honestly, I can’t tell you all the things that this stuff does cause it’s just way too long a list and way too cool. But what I can tell you is that as far as wireless transmission goes, this is pretty much as high-tech as it gets.
You probably won’t use this stuff on set so much (the box is too big) but the LAV portions of this set-up are amazing, lightweight and top of the line. If you’re looking for as-good-as-it-gets sound transmission, look no further, Sennheiser has it for you. Not for amateur use, there’s cheaper stuff for that.
