Application Diagram
Description:
The Octava HD41-ARC HD video and audio switch is designed to
enhance HD display system integration with optical audio based sound
system for optimal viewing and listening experience.
Built in EDID Management is configured with 2Ch PCM,5.1 audio
fields ensuring that the connected sources can output 5.1 audio (when
available) when your display does not supported it.
The Optical Audio Output can operate in 3 modes thus allow users
total flexibility:
1) Convert HDMI Input source to Optical Audio Format
2) Convert HDMI ARC from HDTV to Optical Audio Format
3) Switch directly from 4 Optical inputs to the Optical Output
When used in the Optical switching mode, the Optical source can be
independent from HDMI source selection. For example, you may view
a video on the HDTV while listening to a different audio source via
Optical Input.
