ARC soundbars use Audio Return Channel over HDMI to carry TV audio to the soundbar, while eARC supports greater bandwidth for higher-quality formats and advanced surround sound, such as Dolby Atmos. Choose ARC when your TV and sources support standard ARC audio, or choose an eARC soundbar when your TV has an eARC port and your system calls for higher-bandwidth audio.

ARC soundbars typically connect to a TV through an HDMI ARC or eARC port, allowing one cable to carry audio and, on compatible systems, volume and mute commands from the TV remote. If the TV lacks ARC or eARC, many models also support optical or analog audio connections, though those options may require the soundbar’s remote for control.

Yes, many ARC soundbars also support optical or analog audio connections, allowing them to work with televisions that do not have an Audio Return Channel (ARC) port. Check the soundbar and television inputs before installation, then select the matching connection and use the television or soundbar remote to adjust volume.

When selecting an ARC soundbar, compare HDMI ARC or eARC connectivity, supported formats such as Dolby Atmos, DTS:X, Dolby Digital, or DTS, subwoofer configuration, dialogue-enhancement modes, and 4K HDMI support for movie and gaming setups. For music and installation flexibility, also consider Bluetooth streaming, multiroom support, available optical or analog inputs, and the soundbar’s mounting options and profile.
