With the release of AirPlay 2 earlier this year and the follow-up addition of Dolby Atmos support for Apple TV with tvOS 12, there have been significant improvements in the home entertainment experience for Apple users.
While AirPlay 2 support initially launched for HomePod with other speaker and receiver brands to come, the rollout has taken a bit of a time, and in fact there are still only a few brands that support the standard. Sound United's Denon and Marantz brands were the first standalone receivers to gain AirPlay 2 support back in August, and I've had a chance to test out the setup using a Denon AVR-X3500H receiver.

Denon AVR-X3500H
For those unfamiliar with component home theater systems, the AV receiver acts as the center of your entire system, managing both audio and video to connect all of your various content sources to outputs like your television and speakers.
They've become increasingly packed with technology over time depending on how much you're willing to spend, offering support for such features as decoding various surround sound formats, driving an ever larger number of speakers, accepting direct wireless audio streaming via Bluetooth or AirPlay, connecting to Internet services via Wi-Fi or Ethernet, and more.
I've paired the Denon receiver with Focal's Sib Evo 5.1.2 system that includes Dolby Atmos support, giving me the opportunity to check out both of the recent technological additions to the Apple ecosystem for a quick overview.

The Sib Evo 5.1.2 includes two front loudspeakers with upward-firing Dolby Atmos speaker drivers, three satellite speakers with one intended to be turned on its side and used as a center speaker, and a Cub Evo active subwoofer.

Denon's AVR-X3500H can handle eight HDMI inputs and up to three HDMI outputs. With support for Dolby Atmos, DTS:X, and DTS Virtual:X, all of the top surround sound formats are included. Add in AirPlay 2 and Alexa voice control, and you've got a powerful and flexible centerpiece for your home entertainment system.
AirPlay 2
If you're an Apple fan, you likely already have an Apple TV hooked up to your home entertainment system, so you can stream multi-room audio to the system via the Apple TV. But built-in support for AirPlay 2 on the AVR-X3500H and other Denon receivers gives you another option for direct delivery of audio to what in some cases may be the best speakers in your house.

When you set up the Denon receiver for the first time, it walks you through a network setup process that can grab your Wi-Fi network details from an iOS device, getting your receiver online so that it can directly access content and serve as an AirPlay 2 destination. As is pretty typical for electronics like this, the on-screen setup process isn't particularly pretty, but it makes each step clear and relatively easy to navigate through using the receiver's remote.
Once you have the receiver online and set up for AirPlay 2, you'll see it pop up in your list of speakers in the music widget on your iOS device. With AirPlay 2, you can send synchronized audio to multiple speakers located throughout your home and control all of it right from your iPhone, iPad, Apple Watch, or iTunes on Mac.

Setting up the receiver in the Home app lets you assign it to a room and zone, allowing it to integrate with other speakers in various areas around the house.
When sending audio to multiple speakers via AirPlay 2, you'll see several sliders for controlling volume, allowing you to control either individual speakers or the entire set. If you have different speakers set at different volume levels, adjusting the master volume slider will change the individual speaker volume levels proportionally.

You can use AirPlay 2 to route audio directly to an Apple TV hooked up to a home audio system, so I wouldn't run out and buy a whole new receiver just for AirPlay 2 support, but it's nice to have the extra option for direct AirPlay 2 streaming to a receiver if you don't have an Apple TV on that setup or just want to cut out the middleman and stream directly to your high-quality speakers.
Dolby Atmos
Dolby Atmos takes advantage of three-dimensional space to offer a more immersive sound experience for your home theater system, typically using either downward-firing speakers mounted in the ceiling or upward-firing speaker drivers to reflect sound off of the ceiling, and when combined with the rest of the traditional speakers in your system, you'll find sounds coming at you from all angles.
Focal's Sib Evo system uses upward-firing drivers built into the main front left and right speakers. The Atmos drivers use their own speaker wire connections and connect to their own terminals on the receiver, and the Denon manual walks you through exactly which terminals to use for which speakers, as a host of speaker configurations are supported.

A key component of the Dolby Atmos experience is speaker calibration, which ensures that output from the receiver is properly adjusted for optimal sound quality. With different sizes and shapes of rooms, sound can bounce around in unpredictable ways, and it's important that your home audio system be configured for your unique environment. That's particularly true with the Dolby Atmo... Click here to read rest of article
