Video Conference Collaboration
The S850i System is equipped with balanced analog audio input and output to be connected to Aastra’s BluStar for Con-
ference Room solution or PC conferencing system. This allows the S850i Microphones and Speaker to be used as Micro-
phones and Speaker for video calls. It also provides Acoustic Echo Cancelation and Noise Control to the video call.
Connecting a Video Conference System
In the Advanced Audio setting (see "Advanced Audio" on page 55), change the Aux Audio setting for Aux Out to MIC. Then
connect one of the AUX OUT on the S850i Wireless Base Unit via an appropriate mono balanced or unbalanced cable with
3.5mm plugs to the "Mic Input" on the video conference system.
The line level audio AUX IN on the S850i Wireless Base Unit should be connected, via the appropriate mono balanced or
unbalanced 3.5mm cable, to the "line output" of the video conference system.
As the S850i System provides the Echo Cancellation for the call, any Echo Canceller in the video conferencing unit should
be switched off. Not switching off the Echo Canceler in the Video Conferencing unit might negatively affect the audio on
the S850i Speaker and Microphones. Please visit the documentation of your video conferencing unit on how to disable the
Echo Canceller.
Any audio device like external speaker or TV speaker attached to the video conferencing unit needs to be disabled. The
S850i Speaker and Microphones become your only audio devices for the video conferencing call. Any other devices will
affect the Echo Canceller and will cause negative impact on the audio of the call.
Configuring the Analog Audio
The AUX IN and AUX OUT connectors have to be configured in the right way to receive best results with your video confer-
encing unit. This requires testing and setting of the values in your environment. See "Advanced Setup" on page 55 on set-
ting the volume for the AUX IN and AUX OUT connectors and how to set the level (Microphone level or Line level) for the
AUX IN connector.
Making a Video Call
The S850i System acts as a wireless Microphone, Speaker and mixer for the video conference call. Simply remove the
Microphones from the Charger Tray to activate the analog audio input.
Note:
For security reasons the S850i Microphones will not send any audio to the AUX OUT while in the Charger Tray. The
Microphones have to be removed from the Charger Tray to send audio data to the AUX OUT connector.
