Polycom Vortex EF2241 Application Note

Polycom iPower 9000 Series
CONNECTING THE IPOWER 9000 SERIES INPUTS AND
OUTPUTS
In order to send and receive audio to the Polycom iPower 9000 Series codec, you need to observe the
following procedure:
1. Connect one of the Outputs of the Vortex device to the left channel (colored white) of Input 2. Only
use the left channel of Input 2. By default, Outputs A-C of the Vortex device are mix-minus
versions of the Inputs A-C signals.
Do not use the PowerMic Input to send audio into the codec.
2. Connect the left channel line level output of the codec (colored white) 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.
