When you enable it for non-Atmos multi-channel content, the Dolby surround upmixer expands the audio so that it takes advantage of your entire system, including the ceiling or Dolby Atmos enabled speakers while still honoring and maintaining the artist’s intent for the mix. Dolby surround upmixer replaces the Dolby Pro Logic II family of upmixers, offering greater flexibility and superior audio performance.
Unlike previous wideband upmixing technologies, the Dolby surround upmixer operates on multiple perceptually spaced frequency bands for a fine-grained analysis of the source signal. Dolby surround upmixer can individually steer frequency bands, producing surround sound with precisely located audio elements and a spacious ambience. The Dolby surround upmixer will provide audio to the same set Dolby Atmos enabled or ceiling speakers configured in your system.
Unlock the Dolby Atmos® experience by adding a minimum of one pair of in-ceiling speakers, Dolby Atmos enabled speakers or Dolby Atmos enabled add-on speaker modules to your compatible Onkyo Receiver.
Set your Blu-ray Disc or media player to direct bitstream output, insert your Dolby Atmos®-encoded Blu-ray, and be transported to another world of sound.
