ARC and eARC: The Audio Feature that Enhances Your Home Theater Experience

With the boom in flat screen TVs, high-performance projectors, gaming monitors and audio equipment, the electronics needed to create home theaters with large screens and powerful speakers have become both affordable and readily available for casual streamers and film enthusiasts alike. Learning to set up may seem hard at first, but one key thing that these newcomers might not know is that their TVs, projectors or gaming monitors may already be equipped with the feature that will make creating their own home theater an even smoother and more straightforward process, and by that, we are talking ARC.

What is ARC?

ARC, or Audio Return Channel, is the feature that allows any HDMI port with ARC to both send and receive audio signals for cinema-quality sound. On TVs, projectors or monitors, this functionality allows it to be connected to any compatible sound system or soundbar and easily output the audio from the TV, projector or monitor’s native content. In an alternative scenario, TVs, projectors or monitors can pass on full resolution audio from connected devices such as set-top box, gaming consoles, or Blu-Ray players. Read on and learn how to connect with four easy steps.

This functionality greatly reduces the number of connections needed to setup a home theater, since a single connection between a TV/projector or monitor and a soundbar can deliver audio signals from all connected sources to the soundbar, and two, it consolidates and simplifies the type of connections used, since a user will only need to purchase HDMI cables to connect all their devices. Lastly, it allows the home theater to take advantage of the speed and bandwidth of the HDMI interface to support audio formats, such as Dolby Atmos, which other type of connections might not.

What is eARC?

As mentioned above, most TVs and projectors on the market in the last decade do feature at least one HDMI port with ARC capabilities, but as the consumer electronics market evolves at the pace that it has these past few years, the next generation of ARC has already arrived with eARC, or Enhanced Audio Return Channel. eARC is the latest iteration of ARC that implements the most recent HDMI 2.1 specifications to further bolster its already high bandwidth and speed. With this added capacity, eARC can deliver even higher quality audio formats such as Dolby TrueHD and DTS-HD Master to keep it in step with the advances made on the video side of the home theatre equation. Thus, with eARC, you are able to match the next-level visuals of your 4K 120” projector with sound that is able to recreate object-based effects and true three-dimensional sound for the full cinematic experience you expected to have.
