ARC has an automated lip-sync feature, so theoretically, you’ll no longer need to jump into delay settings on your TV or audio gear to get a perfect match of sound and picture, the way you sometimes need to do when using HDMI ARC or optical connections. For HDMI ARC, you’ll need a TV with an HDMI ARC port, and a soundbar, AV receiver, or another audio device with a corresponding HDMI ARC port. With HDMI ARC, you can ditch your soundbar or receiver’s remotes - as soon as you start watching content that originates from your TV, your connected soundbar or receiver will automatically switch to the correct input. For instance, while Dolby TrueHD gives Atmos its best showing, TrueHD can also be used to deliver lossless versions of less exotic audio content like 5.1, 7.1, or plain-old two-channel stereo. Without an eARC port on your TV, it won’t matter if you have the most expensive Blu-ray player connected to one of its other inputs - you won’t be able to transmit hi-res, lossless audio (whether Dolby Atmos or any other format) to your external audio devices. Right now, eARC is going to be most useful for folks who connect all of their content devices to their TV’s HDMI inputs, instead of the inputs on a soundbar or AV receiver.

What equipment do I need for HDMI ARC or eARC? You’ll also need an HDMI cable to connect these two devices - virtually any HDMI cable will do the job as HDMI ARC is not especially demanding when it comes to bandwidth. I really don’t even like referring to it as "the set top box proposal" because the proposal is really aimed at the future of TV-video viewing via apps and connected devices. That’s why we now have enhanced Audio Return Channel (eARC), which has plenty of capacity and can handle lossless hi-res audio up to 24-bit/192kHz, which should satisfy even the most demanding audiophile. This is why positive identification of slow-moving vehicles is important. Even if you don’t plan to take advantage of their benefits immediately, most AV purchases are going to be around for at least 10 years. It’s especially handy for those who own a Dolby Atmos-capable soundbar, like the Sonos Beam (gen-2), Sonos Arc, or Bose Smart Soundbar 900 as these speakers don’t have their own HDMI inputs. Some TVs have their own streaming apps or TV tuners.

There’s also the possibility that streaming services will decide to offer lossless audio as an upgrade in the future. From there, you create a Roku account, and then you can access over 200 streaming channels, including HBO, Amazon Instant and Pandora. The end result might be the same -- you can drive your car again, after all -- but engine control modules and units do sometimes go bad, and they aren't really designed to be repaired -- at least, not by the owner or by an average mechanic. For example, when I turn on the lighting in my office, the battery voltage will drop from 12.9 V to about 12.1 V. After a few hours of use, it will be at 11.7 V or 11.8 V. However, when I turn off the lights at the end of the evening, the voltage rebounds to 12.5 V or 12.6 V. When the battery is charging during the day, what is control cable the voltage reading indicates the state of the charge. However, if you’re buying a small TV for a kitchen or bedroom, and you have no intention of ever connecting it to an external soundbar or receiver, you can probably stick with HDMI ARC (or indeed, no HDMI ARC).

However, throw a newer surround sound format at it, like Dolby Atmos or DTS:X, and it chokes. So is eARC just about getting better Dolby Atmos? But physical media, like Blu-ray discs or game discs for consoles, along with certain downloaded music files, use a higher quality version of Dolby Atmos thanks to the lossless, hi-res capabilities of Dolby TrueHD. That’s a huge difference and it gives eARC the ability to pass a variety of hi-res audio formats. Should my next TV, soundbar, or AV receiver be equipped with HDMI eARC? Before the advent of HDMI ARC, if you wanted to hear these sources on your receiver’s speakers instead of the ones built into your TV, you needed to run a second cable (typically an optical cable) from your TV back to your receiver. But there’s still the chance that you’ll have a high-end audio source plugged into your TV, and at these times eARC would be handy. Beyond that there are dozens of reasons not to perform these procedures and certainly more reasons not to have it done. But the eARC specification does not require that eARC devices are backward compatible, so there may be some instances where this doesn’t work at all.
