10 Audio-Board
The optional audio board has two line-in interfaces, Lin-In and Mic-In and
two line out-interfaces, Line-out and Head-out. It also has a serial interface
for future use.
In this firmware version, the audio interface works only as an intercom
solution. It builds a bidirectional audio-channel between a transmitter and a
receiver.
To activate the audio function, select the “audio” (audio board) icon in the
“stream” folder on the receiver unit.
This audio stream will be streamed parallel to the video/audio-stream from
the main board. The stream is not compressed and HDCP and FEC have no
functionality in this stream.
In the folder “audio,” select whether “Line-In” or “Mic-In” should be active.
You can also adjust the gain and boost the Micro-In with +20 dB.
