Connecting Audio Input
Make sure that the system is powered off before you connect devices to it.
To pick up audio from your site, you must connect a microphone to the Polycom RealPresence Group
systems. Refer to your system’s setup sheet for connection details.
For more information about connecting audio inputs to RealPresence Group systems, refer to System Back
Panel Views on page 171.
Connecting Polycom RealPresence Group System Table or Ceiling Microphone
Arrays
Polycom microphone arrays contain three microphone elements for 360° coverage. You can connect
multiple Polycom microphone arrays to a Polycom RealPresence Group system.
For the best audio experience, do the following:
● Place the microphone array on a hard, flat surface (table, wall, or ceiling) away from obstructions, so
the sound will be directed into the microphone elements properly.
● Place the microphone array near the people closest to the monitor.
● In large conference rooms, consider using more than one microphone array. Each Polycom
microphone array covers a 3-6 foot radius, depending on the noise level and acoustics in the room.
Using the Polycom EagleEye™ View and EagleEye Acoustic Microphones
Polycom EagleEye
TM
View and EagleEye Acoustic cameras include built-in stereo microphones. The
following tips can help you achieve the best audio when using these cameras:
● Enable Polycom StereoSurround.
● Place the camera at least 1 foot away from any walls to minimize boundary effects.
● Ensure that the people speaking are no more than 7 feet away from the EagleEye View or EagleEye
Acoustic camera. The maximum distance covered depends on the noise level and acoustics in the
room. If you connect a Polycom microphone, Polycom SoundStation
®
, or Polycom SoundStructure
®
to the RealPresence Group system’s microphone input while an EagleEye View or EagleEye
Acoustic camera is connected to the system, the camera’s built-in microphones are automatically
disabled.
● Polycom recommends connecting other audio input devices in conference rooms larger than 12 feet
by 15 feet.
