The unit allows you to enjoy audio in a variety of listening
modes. This section lists the types of listening modes
available on the unit and describes their functions.
¼ Future listening mode update
A future firmware update is planned to enable the unit to
support playback in DTS:X audio format. For this reason,
the available listening modes will vary depending on the
firmware version.
Versions before the release of an update with support for
the DTS:X audio format
Neo:6 Cinema and Neo:6 Music are available.
Versions that support the DTS:X audio format
DTS:X and DTS Neural:X are available. (Neo:6 Cinema
and Neo:6 Music become unavailable after the update.)

¼ AllCh Stereo
Ideal for background music, this mode fills the entire
listening area with stereo sound.
¼ Direct
In this mode, audio from the input source is output as-is.

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.

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.
