In the first place, that TV studio has been designed to present the very best in entertainment, so the gear and the acoustics are the best.
But one thing to which you should definitely pay attention, and at is levels. Broadcast follows the RP200 level standards.
Even shows thsat you think might be 'hot', aren't. MTV, for example, will not play any video with ANY material over -6. They simply will not air it, no matter who it is from.
I've atteneded many industrials wherein the idot who mixed the content for some of the DVDs went with full scale digital, and of course they were embarassed as their material overloaded every player in the place and the presenters could not show their work until the video crew rounded up some in line pads.
Also, be sure to mix on full range speakers. I have experienced NS10 mixes played back on full range systems,a nd it can get pretty ugly pretty quickly.
