AYOUT
The audio components for the room are 16 tabletop microphones, 2 Vortex EF2280's, 1 video codec, 1
program audio source, 1 SoundStation VTX 1000, 1 Vortex EF2201, and 8 ceiling loudspeakers.
Microphones 1-8 will be connected to Vortex EF2280 ID 00 and microphones 9-16 will be connected to
Vortex EF2280 ID 01. The interface module will use Input B / Output B. The video codec will use Input A /
Output A. The program audio will use Inputs C and D. The amplifier will use Outputs 1 and 2 and the
subwoofer will use Output D. There will be 2 sound reinforcement zones with 4 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 EF2201 so that narrowband telephone
calls can be controlled via an external control system. The P HONE jack of the Vortex EF2201 is connected to
the phone jack on the VTX Interface Module in order to facilitate wideband calls from the SoundStation VTX
1000.
