Dolby Atmos® and Dolby Atmos Height Virtualization - Feel every dimension in Dolby Atmos. Enjoy a 5.1 surround speaker system and two additional overhead speakers or two Dolby Atmos elevation speakers, delivering dramatic overhead effects for truly enveloping audio. For those without in-ceiling or upward firing speakers in their system, Dolby Atmos Height Virtualization technology can simulate the Atmos experience. Configure up to five speakers to replicate the effect of two in-ceiling speakers, or utilize all seven channels to simulate the powerful effect of four overhead speakers.
