The Polycom Vortex ® mixer connects directly to audio input 1 on a Polycom
HDX 9000 series system or the AUX audio input on a Polycom HDX 8000
series or Polycom HDX 7000 series system. For more information about
configuring the Polycom HDX system to use a Polycom Vortex mixer, refer to
Polycom HDX System Settings for a Polycom Vortex Mixer
Connecting a Polycom audio 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. Refer to the Integrator's Reference
Manual for Polycom HDX Systems for connection details.
Points to note about the SoundStructure digital mixer:
• Connect a SoundStructure digital mixer using the digital microphone input on
the Polycom HDX system.
• Adjusting the volume on a Polycom HDX system changes the volume of the
SoundStructure digital mixer that is connected.
• The following configuration settings are not available on a Polycom HDX 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 HDX system Line Output is muted when a SoundStructure digital
mixer is connected.
• All echo cancellation is performed by the SoundStructure digital mixer.
You must connect at least one speaker to Polycom HDX 9000 series, Polycom
HDX 8000 series, Polycom HDX 7000 series, and Polycom HDX 6000 series
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
HDX 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. For more information, refer to the Integration Guide
for the Polycom ® SoundStation
HDX ® System in Unsupported VoIP Environments and User Guide for the
Polycom ® SoundStation ® IP 7000 Phone Connected to a Polycom HDX
Unsupported VoIP Environments on the Polycom web site.
Refer to your system's setup sheet for connection details. Make sure that the
system is powered off before you connect devices to it.
