In this mode, audio from the input source is output as-is.

of channels present.

Introduced first in the cinema, Dolby Atmos brings a 

revolutionary sense of dimension and immersion to the 

Home Theater experience. Dolby Atmos is an adaptable 

and scalable object based format that reproduces 

audio as independent sounds (or objects) that can be 

accurately positioned and move dynamically throughout 

the 3 dimensional listening space during playback. A key 

ingredient of Dolby Atmos is the introduction of a height 

plane of sound above the listener.
