Listening Mode Types
In alphabetical order
AllCh Stereo
Ideal for background music, this mode fills the entire listening area with
stereo sound.

Direct

In this mode, audio from the input source is output as­is. For example, if a 2
ch source from a music CD is input, the output will be stereo, or if Dolby
Digital signal is input, the sound field will be controlled in accordance with
the number of channels present.
Dolby Atmos
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.
