Dave,
 
Here are some links with additional information on both the system and the 
theater requirements.

I work for Dolby Laboratories, although not in the Cinema group.  I record 
classical music (mostly choral and chamber) as my passion, and have recently 
expanded my mic selection to include a Soundfield SPS200 in addition to my 
Schoeps DoubleMS rig for 4.0 surround - which explains why I am here.  :-)
