4.11 Content Audio connection

About content audio (no speakerphone connected)
The ClickShare Button captures the audio output of the user's laptop and sends it to the Base Unit together
with the video signal. The audio can be output at line levels from the mini jack socket (3.5mm), TOSLINK
socket or via the HDMI connector (can be set in the configurator).
It is up to the user to decide whether or not to send the audio signal together with the video signal. The user
can decide this by using the same tools as he would to control the laptop's speakers or a headphone: the
audio controls of the operating system or the physical buttons on the keyboard of their laptop (mute/unmute,
lower volume, higher volume).
There will be synchronization between the audio and video signal when the user is sharing content.
About content audio (speakerphone connected)
The content audio captured on the user' laptop is transmitted via the sharing Button to the Base Unit and is
send to USB port with speakerphone connected.

necessary. The audio signal is sent together with the video signal to the display.

is attached.
