Unpacking the Speakers
Use care when unpacking the speakers. Remember to keep the original
boxes and packing material,in the unlikely event the speakers need servic-
ing, or if you move.
Removing the Grilles
The included grilles are attached to the top of the enclosures with plastic
stems that are inserted into rubber grommets. If you wish to remove the
grille to view the speaker element,simply grasp the frame of the grille cover
and gently lift the grille out.To re-attach it, reverse the process by lining up
the plastic stems into their corresponding receptacles and push down on
the grille frame.

What is Dolby Atmos
What is Dolby Atmos?
Dolby Atmos® adds the essential characteristic that’s been missing from
the home theater experience: the sense of true audible three-dimension-
ality. Dolby Atmos-encoded movies deliver this experience, like no other
movie format can.
You’ll get a great immersive experience, no matter what kind of Dolby
Atmos home theater setup you have.Dolby Atmos content is mixed as audio
objects instead of traditional channels.This means the content is not tied to
any specific playback configuration. Further, the technology automatically
adapts the object audio to take full advantage of the number and place-
ment of your speakers, from systems with five speakers on the floor and
two speakers producing overhead sound to a system with as many as 24
speakers on the floor and 10 speakers producing overhead sound.
Additionally,the new Dolby surround upmixer used in today’s A/V receivers
and Processors allows for legacy channel-based content that has not been
mixed for Dolby Atmos to be expanded to fill the flexible speaker layouts
of a Dolby Atmos system providing a new dimension to your old movies.
Description
TheAtlantic Technology 44-DA speaker was specifically designed to be used
as the“elevation” component in a Dolby Atmos surround system.
Working closely with Dolby Laboratories, Atlantic Technology’s research
and engineering team developed the 44-DA with its unique vertically-firing
Concentric Driver Array (CDA™) to deliver the excitement and realism of
Dolby Atmos-encoded soundtracks with startling impact and holographic,
three-dimensional realism. The 44-DA’s frequency response and radiation
pattern have been specifically engineered to meet these requirements.
The 44-DA speaker itself embodies the same high quality compo-
nents—such as its long-excursion damped polypropylene 5 ¼”woofer, 1”
silk-damped dome tweeter and optimized 1st-order Butterworth cross-
over—and meticulous attention to detail that are the hallmarks of all
Atlantic Technology products.
The speaker module is designed to fit perfectly on top of Atlantic Technology’s
THX- certified 4400 LR speakers, creating an integrated,“one-piece” look.
Additionally,because of their compact design and neutral appearance,the
44-DAs are well suited to being used on top of other speakers or, equally
important, as “stand-alone” Dolby Atmos enabled speakers as part of a
complete Dolby Atmos system.

Placement in a Dolby Atmos-enabled
System
The 44-DA delivers the “overhead” dimension in a Dolby Atmos-enabled
home theater system.The Dolby Atmos-enabled speakers are used in addi-
tion to the usual speakers in a 5.1 or larger home theater system.
The 44-DA speakers allow you to experience overhead sounds when the
speaker is placed at the same level as a traditional speaker. These Dolby
Atmos-enabled speakers direct sound upward to reflect off the ceiling,
as Figure 3 shows, to create a faithful reproduction of audio coming from
above.
Figure 3
VERY IMPORTANT: The 44-DA speaker projects its sound from the
top of the cabinet, not from the front like a conventional speaker.
Do not place anything on the cloth grille on the top of the speaker,
place the speaker in a cabinet or below a shelf. These situations will
obstruct the sound path, impairing the performance, and possibly
damaging the speaker elements beneath the cloth.

Three Basic Configurations
We will cover three basic configurations for Dolby Atmos systems. See Fig-
ure 8 opposite page.
• A 5.1.2 system, in which there are two 44-DA speakers in
addition to the existing five speakers
• A 5.1.4 system, in which there are four 44-DA speakers in
addition to the existing five speakers
• A 7.1.4 system, in which there are four 44-DA speakers in
addition to the existing seven speakers
In all three system configurations, one pair of 44-DA speakers is located
at the front of the room, very nearby or on top of the front Left and Right
speakers.For optimal effect and to minimize the distracting effect of audio
radiating directly at the listener position, the 44-DA should be no lower
than the ear height of a seated listener.Also,try to avoid placing the speaker
higher than one-half the height of your wall.
The 44-DA is sized and styled to fit perfectly on top of Atlantic Technology’s
THX-certified 4400 LR as shown. See Figure 4.
However, the 44-DA can be used with any high quality Left/Right speaker,
from Atlantic Technology or another quality speaker brand.See Figure 5.
If space or room/furniture layout restrictions dictate that you cannot place
the front 44-DA speakers directly atop the front L/R speakers, then place
the 44-DA’s as follows:
Laterally: within 2-3 feet max of the associated L/R speaker
Ve r t i c a l l y : at least as high, but no more than 18” higher than the associ-
ated L/R speaker
For the side or back surround channels in a 5.1.4 or 7.1.4 system:
Either place the 44-DA directly on the associated surround speaker,or place
it no more than 2-3 ft away laterally and within ±18”vertically.
NOTE: If you are incorporating the 44-DA’s into an existing 5.1 or 7.1 sys-
tem with Dipole/Bipole surround speakers we recommend you set the sur-
round speakers to Bipole and move them to ear level height if possible.
If you need guidance for a more complicated setup, or if you want more
information about Dolby Atmos please visit their website at http://www.

Combination: Overhead and Dolby Atmos Enabled
Speakers
In some instances,a home theater system may already have overhead speak-
ers that can be used to generate overhead audio. In this case, Dolby Atmos
enabled speakers may be used to complement existing overhead speakers
to create a full, four-speaker height experience. If existing speakers are in
the front of the room,then Dolby Atmos enabled speakers may be used in
the rear of the room and vice versa.

Connecting Your System
Speaker Placement
Connecting Your System
We recommend that you connect your system using high quality dual
conductor stranded wire of 16 gauge or heavier, for lengths up to 25 feet
(8m). Remember, the lower the gauge number, the heavier the wire. Use
heavier gauge wire for longer runs. Please contact your audio/video dealer
or installer for specific cable recommendations and further information
regarding special circumstances.The terminals themselves are designed to
allow the use of very heavy speaker wire or angled pin connectors.
WARNING: To prevent risk of electrical shock or damage to your
equipment, always switch off the amplifier or receiver when making
any system connections.
You can connect your speakers by using angled pin connectors,or you can:
1. Remove ½”(13mm) of insulation from each wire end.
2. Twist the stranded wire together, keeping the two ends
separate.
3. Place the appropriate wire through the postholes in the
connectors. These holes are revealed when you push on the
connector’s cap.
4. Release the cap to “grab” the wire.
We recommend that you check your local electrical codes to make sure that
you are not using improper connectors.
It’s important to observe polarity while making speaker connections:
Red (+) terminals on the amplifier to red (+) on the speaker, black (–) on
the amplifier to black (–) on the speaker.
Look carefully at the wires you are using and note that one of the conduc-
tors of each pair will typically be identified either by color, printing on the
outer jacket, ridges on the outer jacket, or a thread intertwined with the
wire strands.
By convention,the marked wire is connected to the red (+) terminal.
Whether you are connecting a complete system,or adding a single speaker
component to your present system, the wiring should look like the system
wiring diagrams on the opposite page. Because terminology varies among
manufactures please consult your A/V Receiver or Processor’s instruction
manual to identify the proper terminals to use when connecting Dolby
Atmos-enabled speakers. In many cases they will be identified as either
Dolby Atmos or Elevation or Height channels.
WARNING: Before turning on the amplifier, be certain that no stray
wire strands are touching across any terminals as this might damage
your amplifier.
