Connecting Non-Polycom Microphones or a Mixer to a Polycom HDX System
You can connect up to two microphones directly to the Polycom HDX system,
or you can connect several microphones to the Polycom HDX system through
an audio mixer. Refer to your system’s setup sheet for connection details.
Connecting a Polycom Vortex® mixer to Polycom HDX systems provides
flexibility in audio setup. For example, it allows you to provide a microphone
for each call participant in a boardroom. For top performance, you need Vortex
firmware 2.5.3 or later and Conference Composer™ version 3.0.1 or later.
For more information about connecting non-Polycom microphones, refer to
Settings for Non-Polycom Microphones on page 4-10.
