The audio components for the room are 12 tabletop microphones, 1 Vortex EF2280, 1 Vortex EF2241, 1 video 
codec, 1, 4-channel amplifier, 1 program audio source, 1 SoundStation VTX 1000, and 8 ceiling 
loudspeakers.   Microphones 1-8 will use Inputs 1-8 on the Vortex EF2280 and Microphones 9-12 will use 
Inputs 1-4 on the Vortex EF2241.  The video codec will use Input A / Output A of the Vortex EF2280.  The 
program source will use Inputs B and C of the Vortex EF2280.  The Interface Module for the SoundStation 
VTX 1000 will use Input B / Output B of the Vortex EF2241 and the subwoofer will use Output D of the 
Vortex EF2241.  The amplifier will use Outputs 1-4 of the Vortex EF2280.  There will be 4 sound 
reinforcement zones with 2 loudspeakers assigned to each zone. 
  
We will assume that the microphones, program audio, and amplifier have balanced connections (.775 Vrms 
professional nominal levels).  The Interface Module, subwoofer,  and video codec will have unbalanced 
connections (typically .3 Vrms consumer nominal levels).   
 
We will set the output to the subwoofer at -30 dB in order to protect the subwoofer from "bottoming out" 
on high-amplitude transient sounds.    
 
The telephone wall jack is connected to the L
INE
 jack of the Vortex EF2241 so that narrowband telephone 
calls can be controlled via an external control system.  The P
HONE
 jack of the Vortex EF2241 is connected to 
the phone jack on the VTX Interface Module in order to facilitate wideband calls from the SoundStation VTX 
1000.
