in the network.

Advanced Mode: Audio

You can set the gain of the audio signals to suit your specific requirements. The current video
image is shown in the small window next to the slide controls to help you check the audio
source and improve assignments. Your changes are effective immediately.
If you connect via Web browser, you must activate the audio transmission on the LIVEPAGE
Functions page (see Section 10.13 Advanced Mode: LIVEPAGE Functions, page 76). For other
connections, the transmission depends on the audio settings of the respective system.
Audio
The audio signals are sent in a separate data stream parallel to the video data, and so increase
the network load. The audio data are encoded according to G.711 and require an additional
bandwidth of approx. 80 kbps for each connection. If you do not want any audio data to be
transmitted, select Off.
Line In 1
You can set the line input gain. Make sure that the display does not go beyond the green zone
during modulation.
