Dolby Surround Upmixer
When you invest in a Dolby Atmos home theater, you expect to get full use of all the components, even when the content you are playing is not mixed in Dolby Atmos. This includes taking advantage of overhead and Dolby Atmos enabled speakers to further enhance the playback experience.
Included in the Dolby Atmos technology bundle is a new advanced upmixer designed to be compatible with traditional channel-based as well as Dolby Atmos speaker systems. The Dolby surround upmixer expands the audio of channel-based content, including native stereo, 5.1, and 7.1 content, for playback through a Dolby Atmos system-regardless of speaker number or placement-while simultaneously honoring and maintaining the artist’s intent for the mix.
The Dolby surround upmixer analyzes and processes multiple perceptually spaced frequency bands, accurately steering each individually. The result is a surround playback experience characterized by precisely located audio elements and a more spacious ambience.
In a Dolby Atmos system, the channel-based mix is fully honored. Dolby Atmos enabled speakers and overhead speakers are employed to lend a sense of atmospherics or room effect to the listening experience. This new technology will process and upmix channel- based content to as many as 17 speaker locations at listener level and to 10 Dolby Atmos enabled or overhead speakers. Note: To maintain an accurate frontal audio image, the upmixer will not send upmixed audio to the left wide and right wide speakers or any speakers that are located between the left, center, and right speakers. Audio is not upmixed to the center surround speaker.
A center spread on/off control enables you to spread the center image across a wider front soundstage. This optional feature is ideally suited for playback of two-channel music content or playback of channel-based content in a home theater design that employs a wider screen configuration than typical installations.
Select the Dolby surround and center spread function from the user interface of the AVR or preprocessor, or from the system’s remote control.
