I've been asked to put some numbers together for a location recording of 60 pc orchestra, performing live to clicktrack & picture. (We have the hall, the players are union, and there's a finite budget already in place.) The conductor wants a click track into headphones for all 60 players (!!!) in addition to two plasma screens - one for him and one for the players, both playing picture from a DVD with burned-in time code and click track. Aside from the obvious logistical aspects of this, (I have plenty of mics and multitrack recording capabilities to pull off the recording side of things), I will need prices for headphone amps & rentals. Anyone have any contacts or knowledge of cost and availability for this sort of thing? I will be building a price list for the HP and amps rental for a 3-day session. (Which will mean probably four day rental - delivery & return, etc.) I'll probably have to rent from NYC or anywhere else on the East Coast, but I'm open to suggestions. I can't tell you who it's for yet, but if it happens, I'll tell all once it's completed.
