是否需要支援 HDMI eARC 的電視?
No. Beam (Gen 2) can connect to TVs with eARC, ARC or optical outputs. For greatest compatibility, eARC is recommended.
If you connect to a TV with eARC, the Dolby audio formats supported include Dolby Atmos, TrueHD, MAT, Dolby Digital Plus, and Dolby Digital.
If you connect to a TV using ARC, the Dolby audio formats supported are dependent on your TV model and manufacturer. The TV may be capable of sending Dolby Atmos, Dolby Digital Plus and Dolby Digital. An ARC connection cannot support TrueHD or MAT.
How do I know if I'm getting Dolby Atmos?
Dolby Atmos is dependent on the source material as well as the TV passing an Atmos signal through the HDMI port. If the soundbar is receiving an Atmos signal, this will be displayed on the Now Playing screen and Settings menu in the Sonos app.
If you connect to a TV using the optical adapter, the Dolby audio formats supported are dependent on your TV model and manufacturer. The TV may be capable of sending Dolby Digital. An optical connection cannot support Dolby Atmos, TrueHD, MAT, or Dolby Digital Plus.
