CobraNet by Peak Audio was first (Score 1)

But this is nothing new -- Peak Audio's CobraNet has been used for several years for exactly this purpose -- moving multichannel pro or semi-pro audio from place to place in a venue. http://www.peakaudio.com/CobraNet/ It really shines in venues like sports arenas or outdoor concerts with significant distances involved. It's much more cost-effective than long multichannel snakes. Rane http://www.rane.com/nm84.html and QSC http://www.qscaudio.com/products/amps/rave/rave.ht m Peavey http://mediamatrix.peavey.com/ (and others) even build CobraNet input modules into their power amplifiers. Now I'm just waiting for them to extend it to the emerging 10 Gigabit networking... http://www.10gea.org/ WECo.
