Administrator's Guide for the Polycom RealPresence Group Series

Connecting Non-Polycom Microphones or a Mixer to a

Polycom RealPresence Group System

You can connect non-Polycom microphones directly to audio input 1 on a Polycom RealPresence Group
system, or through a line-level mixer to the AUX audio input on any Polycom RealPresence Group system.
For more information about configuring these non-Polycom microphones, refer to
Microphones on page 79.
You can connect several microphones to a Polycom RealPresence Group system through a Polycom audio
mixer. The SoundStructure C-Series mixer connects to the digital microphone connector on a Polycom
RealPresence Group system, and no configuration is necessary.
Connecting a Polycom audio mixer to Polycom RealPresence Group systems provides flexibility in audio
setup. For example, it allows you to provide a microphone for each call participant in a boardroom. Refer to
the Integrator's Reference Manual for the Polycom RealPresence Group Series for connection details.
Points to note about the SoundStructure digital mixer:
• Connect a SoundStructure digital mixer using the digital microphone input on the Polycom
RealPresence Group system.
• Adjusting the volume on a Polycom RealPresence Group system changes the volume of the
SoundStructure digital mixer that is connected.
• The following configuration settings are not available on a Polycom RealPresence Group system
when a SoundStructure digital mixer is connected: Audio input 1 (Line In), Bass, Treble, Enable
Polycom Microphones, Enable MusicMode, and Enable Keyboard Noise Reduction.
• The Polycom RealPresence Group system Line Output is muted when a SoundStructure digital
mixer is connected.
• All echo cancellation is performed by the SoundStructure digital mixer.

Connecting Audio Output

You must connect at least one speaker to the Polycom RealPresence Group systems in order to hear audio.
You can use the speakers built into the main monitor, or you can connect an external speaker system such
as the Polycom StereoSurround kit to provide more volume and richer sound in large rooms.
When you connect a SoundStation IP 7000 conference phone to a Polycom RealPresence Group system,
the conference phone becomes another way to dial audio or video calls. The conference phone also
operates as a microphone, and as a speaker in audio-only calls.
Refer to your system's setup sheet for connection details. Make sure that the system is powered off before
you connect devices to it.
For more information about connecting speakers to RealPresence Group systems, refer to
Panel Views on page 171.

Placing Speakers to Play Stereo from Far Sites

The Polycom StereoSurround kit is designed for use with Polycom RealPresence Group systems. It
includes two speakers and a subwoofer.
When a RealPresence Group system is configured for Polycom StereoSurround, the audio inputs and
outputs are all treated as stereo. Otherwise, all audio inputs and outputs are mono.
