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.
