You can connect several microphones to a system through a Polycom audio mixer. Connecting a
Polycom audio mixer to RealPresence Group Series systems provides flexibility in audio setup. The

configuration is necessary.
When incorporating a SoundStructure digital mixer, remember the following:
• Connect a SoundStructure digital mixer using the digital microphone input on the room system.
• Adjusting the volume on a system changes the volume of the SoundStructure digital mixer that is
connected.
• The following configuration settings are not available on a system when a SoundStructure digital
mixer is connected: Audio input 1 (Line In), Bass, Treble, Enable Polycom Microphones, Enable M-
Mode
™
, and Enable Keyboard Noise Reduction.
• The system Line Output is muted when a SoundStructure digital mixer is connected.
• All echo cancellation is performed by the SoundStructure digital mixer.
The digital mixer allows you to provide a microphone for each call participant in a boardroom. For
connection details, refer to the Polycom RealPresence Group Series Integrator Reference Guide.
