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 described below.

• 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
• 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
• Optionally connect the RS-232 interface between the VSX 8000 and the Vortex device
