SYSTEM LAYOUT 
 
The audio components for the room are 8 tabletop microphones, 1 EF2280, 1 VSX 8000 video 
codec, 1 program audio source, and 4 ceiling loudspeakers.   The video codec will use Input A / 
Output A.  The program audio will use Inputs C and D.  The amplifier will use Output B. 
 
On the VSX 8000, either the left or right input / outputs can be used for mono operation. 
 
We will assume that the microphones, amplifier, program audio, and VSX 8000 have balanced 
connections.
