At playback, the Dolby Atmos decoder creates a real-time downmix to place each discrete sound as precisely in space as it can, given the available speakers.

With Dolby Atmos, each sound effect can be stored discretely, along with control code that defines the sound's starting and ending position as well as speed of movement and amplitude. This can create a convincing illusion of movement but it is neither efficient, nor precise. For example, If a sound is supposed to travel from left to right of the rear of the soundstage in an existing 7.1-channel DTS or Dolby mix, the rear left channel will start loud and fade to soft while the rear right channel starts soft and becomes louder. In the old channel-based systems, sound positions are effectively hard-coded into the mix.
Dolby Atmos encodes specific sounds with meta data which defines where the sound exists precisely in three dimensional space. Dolby does add discrete height channels into the mix, which can add a new level of immersiveness, but it's the way that sound is encoded and decoded that sets it apart from other surround formats. Onkyo's PR-SC5530 will be one of the first preamp/processors to support Dolby Atmos surround.ĭolby Atmos is more than just "more channels" than its predecessors or competitive surround formats: it is an object-oriented surround platform.

Onkyo is currently expecting to make the Dolby Atmos firmware update available in September of this year. Each of these receivers already includes the option for height channels, a critical component of Dolby Atmos. Onkyo receivers in the current line that will add Dolby Atmos support include the the TX-NR636, TX-NR737, and TX-NR838 networked home theater receivers. Details on pricing and expected availability of the HTiB systems and speaker packages were not available at press time. Other new products which will feature Dolby Atmos include the HT-S7700 and HT-S9700THX HTiB systems, and the SKS-HT693 and SKH-410 speaker packages. All models include height channels as well as additional channel options: The TX-NR1030 supports up to nine speakers with two subwoofers (9.2) while the TX-NR3030 and PR-SC5530 support up to eleven speakers with two subwoofers (11.2). The TX-NR1030 ($1,699) and TX-NR3030 ($2,399) network A/V receivers, and the PR-SC5530 Network A/V Controller ($2,499) are all currently scheduled to ship to dealers in August. Upcoming Onkyo products which will support Dolby Atmos include two high-end receivers and a new flagship preamp/processor. This means consumers will be able to outfit their home theaters with Dolby Atmos surround for under $700 (for the receiver) and they may already own the receiver. But even better, the company also revealed that it will enable Dolby Atmos in several of its current midrange receiver models via a firmware update coming later this year. This morning, Onkyo announced that select models in its upcoming line of audio/video receivers (AVRs) and home theater in a box (HTiB) systems would feature Dolby's newest surround technology, Dolby Atmos.
