Definitive Technology A90 Manuel Du Propriétaire

It’s important to know that the A90 elevation module is a height speaker that bounces sound off a ceiling and 
back toward your viewing area. With that in mind, your ceiling plays an important role in the experience.  

To achieve the best Dolby Atmos or DTS:X experience possible:

• Your ceiling should be flat

• Your ceiling material should be acoustically reflective (examples include drywall, plaster, hardwood or other 

rigid, non-sound absorbing material)

• Ideal ceiling height is between 7.5 and 12 feet

• Maximum recommended height is 14 feet

To experience either revolutionary sound technology, you must have a way to play or stream Dolby Atmos or 
DTS:X content. 
Note: please reference your receiver/processor owner’s manual for complete directions, or give us a call.

Options to Play or Stream Content

1. You can play Dolby Atmos or DTS:X content from a Blu-ray Disc through an existing Blu-ray Disc player. Be 

sure you have a player that’s fully compliant with Blu-ray specifications.

Or

2. You can stream content from a compatible game console, Blu-ray, or streaming media player. In both cases, 

be sure to set your player to bitstream output.
