Video Conference Collaboration
The FLX2 System is equipped with balanced analog audio input and output to be
connected to 3
rd party video or PC conferencing system. This allows the FLX
Microphones and Speaker to be used as Microphones 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 page 44), change the Aux Audio setting for Aux Out
to MIC. Then connect one of the AUX OUT on the FLX2 Base Station 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 FLX2 Base Station should be connected, via the
appropriate mono balanced or unbalanced 3.5mm cable, to the ‘line output’ of the video
conference system. See page 77 for a list of audio cables required for the most
common video conferencing systems available in the market.
As the FLX system provides the Echo Cancelation for the call, any Echo Canceler 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 video call. Please
visit the documentation of your video conferencing unit on how to disable the Echo
Canceler.
Any audio device like external speaker or TV speaker attached to the video
conferencing unit needs to be disabled. The FLX Speaker and Microphones become
your only audio devices for the Video Conferencing call. Any other devices will affect
the Echo Canceler and will cause negative impact on the audio of the call.
NOTE: For security reasons the FLX Microphones will not send
any audio to the AUX OUT while in the Charger Base. The
microphones have to be removed from the Charger Base to send
audio data to the AUX OUT connector.
Configuring the Analog Audio
For best audio results, the AUX IN and AUX OUT connectors have to be configured in
the right way to receive best results with your video conferencing unit. This requires
testing and setting of the values in your environment. See page 40 on setting 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 FLX2 System acts as a wireless Microphone, Speaker and mixer for the video
conference call. Once configured, a video call can be made using the 3
rd party user
interface supplied with the video conference system. Simply remove the Microphones
from the charger to activate the analog audio input.
