Polycom Vortex EF2241 Application Note

Polycom ViewStation EX
CONNECTING THE VIEWSTATION EX INPUTS AND
OUTPUTS
In order to send and receive audio to the Polycom ViewStation EX codec, you need to observe the following
procedure:
2. Connect one of the Outputs of the Vortex device to the mixer input of the codec. By default,
Outputs A-C of the Vortex device are mix-minus versions of the Inputs A-C signals.
4. Connect the auxiliary line level output of the codec to one of the line level inputs of the Vortex
device (Inputs A-D). You may use one of the Mic/Line level inputs, but you need to disable all
processing on that input (AEC, AGC, NC, Automixer), disable Phantom Power, and set the input to
line level versus the default of mic level.
Follow the diagram below to make the proper physical connections to the codec. Do not
use any other audio inputs or outputs as they could cause an audio loopback to occur
within the codec.
