This is the Sennheiser digital 1000 wireless system that I just got from Sennheiser 2 days ago..I had sent mine in for a repair because I was going to sell it and they sent me a brand spankin new unit!! Comes with the hard case,Manual and a rack adapter customized by me to run the cable from the reciever to the front of the rack. 4 internal antenna's so no need for any external but...If your playing a huge stadium you can get the optional surface mount antenna's from sennheiser...$265.00 puts it on your door!!! /emoticons/default_smile.png
