CONNECTING THE IPOWER 600 SERIES INPUTS AND
OUTPUTS
In order to send and receive audio to the Polycom iPower 600 Series codec, you need to observe the
following procedure:
1. Connect one of the Outputs of the Vortex
®
device to the PowerMic Input of the codec. By default,
Outputs A-C of the Vortex device are mix-minus versions of the Inputs’ A-C signals.
You must use the PowerMic adapter cable in order to send audio into the codec. You
may order one by contacing your Polycom reseller and requesting part number CBL-
LINEAUDIO. You can also make your own cable. Click here for instructions.
2. Connect the 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.
