With some help from the
Dolby Setup Guides, here is the way I see it, using the settings available in my NAD T 758 v3.
Dolby ATMOS speaker setup with NAD T 758 v3:
Dolby Enabled = a driver on "top" (see my confusion?) of a speaker with Height sound bouncing off the ceiling and then reaching the listener indirectly.
Top = ceiling mounted driver with Height sound reaching the listener directly.
Dolby Enabled and
Top Modes can both exist in the same system setup.
Confusing Modes Nomenclature:
Dolby Enabled
Surround and Top
Middle
Dolby Enabled
Back and Top
Rear
With two Height speakers total, they are defined by:
NAD Position Setting -
Height 1.
The six possible Mode settings are:
- Dolby Enabled Front or Top Front - two Height speakers in front of the listener
- Dolby Enabled Surround or Top Middle - two Height speakers roughly even with the listener
- Dolby Enabled Back or Top Rear - two Height speakers behind the listener
With four Height speakers total, two are defined by
Height 1 and the other two are defined by:
NAD Position Setting -
Height 2.
Any of the five unassigned Modes above can be used.
Note:
- Although I do not see it stated as a requirement, I would recommend Height 1 speakers being physically in front of Height 2 speakers.
- Although it is allowed in the NAD settings, it is not recommended to use both of any of these pairs of settings in the same system:
- Do not use both the Dolby Enabled Front and Top Front Modes in the same system.
- Do not use both the Dolby Enabled Surround and Top Middle Modes in the same system.
- Do not use both the Dolby Enabled Back and Top Rear Modes in the same system.
