The Concept
Two audio source devices are connected to the trasmitter: a Blu-ray player which has embedded digital
audio on HDMI; and a media player which sends analog audio to the transmitter. On the receiver's side there
is two audio source device: an HDTV which can receive digital audio on HDMI; and an audio amplifier which
can receive analog or digital audio signals as well.
As the transmitter is able to embed the analog audio signal to the HDMI signal, the user can transmit the
audio of the Blu-ray player or the audio of the media player as well.
INFO: One audio (embedded or analog) and one video signals can be transmitted via the optical output
at the same time.
The receiver has built-in de-embedder function so the user can transmit audio signal to the audio amplifier
and HDTV as well.
All related audio settings are available in the Lightware Device Controller software, see the
Windows section.
