Positioning Dolby Atmos
Enabled Speakers
(cont.)
In a 7.1.4 con
fi
guration the back
two Dolby Atmos-enabled speak-
ers should be placed in the back
left and right speaker locations
130 to 150 degrees off axis from
the primary listeners.
If you opt for 2 Dolby Atmos
enabled speakers in a 5.1.2 or
7.1.2 con
fi
guration, you can still
get an immersive experience
with sounds moving overhead.
Simply place the 2 Dolby Atmos-
enabled speakers at the front left
and front right speaker locations
22 to 30 degrees off axis from
the primary listeners.
Mixing Atmos Enabled Height
Speakers with Ceiling Speakers
You can combine Dolby Atmos
enabled speakers with ceiling-
mounted speakers in your home
theater
with certain electronics
(Verify with your AV Receiver
manufacturer)
. This can be useful
if, for instance, you have two
speakers already installed in your
ceiling and want to add two more
height speakers but cannot install
a 2nd pair in or on the ceiling.
Instead, add two Dolby Atmos
enabled speakers and repurpose
the two existing ceiling speakers.
You
wil
l hear the top-level
overhead sounds whether you’re
using ceiling speakers, Dolby
Atmos enabled speakers, or a
combination of both.

Compatibility
Dolby’s TrueHD format, used in Atmos Blu-ray discs, carries Dolby Atmos
content in a special losslessly encoded object-based mix. Dolby Digital Plus™
used by leading streaming video providers supports Dolby Atmos, so you can
play Dolby Atmos content from streaming devices as well. The current HDMI
spec (v1.4 and later) fully supports Dolby Atmos. Dolby Atmos audio tracks are
backward compatible and will play traditional 5.1 or 7.1 audio on non-Dolby
Atmos systems.
For compatibility with non-Atmos recordings
, Dolby Atmos electronics include
an upmixer that upconverts all legacy non-Atmos record
ings
into a surround
experience that uses Atmos height speakers to
playback
a spacious
overhead
ambience
which Atmos extracts organically from the recording
. You can choose
to enable this feature or not.
Home Atmos – Speaker types
Dolby recommends two different ways for Atmos to recreate overhead sounds in
the home with height speakers:
• Dolby-enhanced speakers
add a
top-firing
height
channel to a conventional
forward
fi
ring
LCR type
speaker. Both forward and
height channels have
independent inputs and are
fed by independent outputs
on the AVR
and
ampli
fi
er.
Positioned at listener level
and aimed at an upward
angle, the top height channel
re
fl
ects sound off the ceiling toward listeners. Its
frequency response and directivity must meet very rigid and unique spec
ification
s
in order for Dolby certify it for Atmos.
