Polycom VSX 8000
Please refer to the Application Note entitled “Vortex - VSX 8000 Integration” for complete instructions on
how to connect a Vortex device to a VSX 8000. Basic instructions follow:
CONNECTING THE VSX 8000 INPUTS AND OUTPUTS
In order to send and receive audio to the Polycom VSX 8000 codec, you need to connect the system as
shown in Error! Reference source not found. and described below.
1. Connect one of the Outputs of the Vortex device to the mixer Input of the codec. By default,
Outputs A, B, or C of the Vortex device are mix-minus versions of the Inputs A, B, or C signals,
respectively. Any of these signals can be used with the default factory preset on the Vortex. If you
are using Polycom InstantDesigner™, choose the input and output that InstantDesigner
recommends.
2. Connect the auxiliary line level output of the codec to one of the line level inputs of the Vortex
device (Inputs A-D). If you have more line inputs, you may use one of the Mic/Line level inputs
instead of a line level input, but you need to disable all processing on that Mic/Line input (AEC,
AGC, NC, Automixer), disable Phantom Power, and set the input to line level versus the default of
mic level.
3. Optionally connect the RS-232 interface between the VSX 8000 and the Vortex device.
