This 4K HDMI ARC/eARC Audio Adapter is capable to output Dolby Atmos

audio from an external HDMI source to eARC/ARC sound systems. Since

compliant with audio formats such as LPCM, Dolby True HD and DTS-HD

Master Audio, this adapter is a perfect solution for connecting SONOS

ARC/BOSE 500/BOSE 700 Soundbars and other eARC/ARC audio/video

receivers. It also provides a dedicated HDMI output port for outputting audio

only when connecting with legacy AVR without eARC/ARC function.
