System 220
High Performance Loudspeaker System
Welcome to Atlantic Technology’s world of excellence in sound reproduction. Your new
speaker system is precision crafted to give you years of enjoyable trouble free service.
This manual covers the Atlantic Technology System 220 series of speakers for
home theater. It will show you how to incorporate the following System 220 compo-
nents into your present system as well as how to set up a complete system. (Except the
Model 222 PBM. It is covered in a separate manual.)
The Model 221 LR Front Channel Speakers are two-way systems for use with a
quality subwoofer such as the Atlantic Technology Powered Bass Modules. Each speaker
contains a 4" polypropylene long-throw woofer and a 1/2" ferrofluid cooled tweeter in
an acoustically inert MDF cabinet.
The Model 223 C Center Channel Speaker with ariable Cinema EQ contains
two high power 3-1/2" polypropylene woofers and a 1/2" ferrofluid cooled tweeter. It is
designed for use in home theater systems that use a Dolby Pro Logic decoder.
The Model 224 SR On-Wall/In-Wall Surround Speaker is intended for use in
audio/video sound systems with a Dolby Pro Logic receiver (or a Dolby Pro Logic
decoder and a surround amplifier). Each speaker has two 3-1/2" polypropylene drivers
that are angled and phased to produce ambience without localization for movie
surround sound tracks.
Although the speakers in the Atlantic Technology System 220 are acoustically and
cosmetically matched to each other they may also be used with a wide variety of other
speaker systems.
Note: The 224 SR is not intended for use as a regular right and left front channel stereo
speaker or satellite. Its spatial perfor ance characteristics are not designed for this purpose.
In the Atlantic Technology 220 Series of co ponents, the Model 221 LR fills this role.
Connection
We recommend that you connect your new System 220 speaker components using high
quality stranded wire of 18 gauge or larger for lengths up to 25 feet. Use 16 gauge or
larger for longer runs of wire. Contact your local audio/video specialist for more specific
information.
Warning: To prevent risk of electrical shock or da age to your equip ent, always switch off
the a plifier or receiver when aking connections to the speaker.

You can connect your System 220 speakers by using
spade lugs or “banana” connectors, or by removing 1/2"
of insulation from eac wire end, twisting t e strands
of wire toget er, placing t e wire t roug one of t e
post oles and screwing down t e nut tig tly.
It is important to observe polarity w ile making speaker
connections: red (+) terminals on t e amplifier to red
(+) on t e speaker, black (-) on t e amplifier to black (-)
on t e speaker. Look carefully at t e wires you are using and note t at one of t e wires
in eac pair is marked by eit er a different color, printing, ridges, or a t read inter-
twined wit t e wire strands. Conventionally, t e marked wire is connected to t e
red (+) terminal.

W et er your are connecting a complete System 220, or adding one speaker compo-
nent to your present system, t e wiring s ould look like t e diagram in Figure 2. Before
turning on t e amplifier, be certain t at no stray wire strands are touc ing across t e
two terminals as t is mig t damage your amplifier.
Finally, c eck t e polarity of your front speakers by listening to some music. If t e
sound seems ollow, spread out and as weak bass, rec eck your connections for proper
polarity and reverse t e connections if necessary.

Placement
The design of the System 220 provides you with maximum flexibility when creating a
large, seamless, acoustically accurate soundfield for your home theater or music system.
The best placement of the various components will vary from system to system. Use the
following placement guidelines and Figure as a starting point. Feel free to experiment.
Home Theater
For a home theater system, place your Model 221 LR speakers on either side of the
television. All of the System 220 speakers (except the Model 222 PBM Powered Bass
Module) are magnetically shielded so that they will not interfere with your television
picture. The left front and right front speakers should be far enough apart that you get a
good stereo image, but not so far apart that the sound seems to come directly from the
speakers, distracting you from the picture. If you are using a center channel speaker, a
wider separation of the left and right front speakers is usually possible.
The Model 22 C should be placed directly on or under your television. Place the
speaker base so that the foot cutouts are facing forward. Then, set the speaker on its
base and tilt the speaker so that it points directly at the listener.
The 224 SR’s size and shape allows greater flexibility in placement than most conven-
tional surround loudspeakers. Due to their spatial characteristics, it is possible to place
the speakers virtually anywhere, but usually the best location is nearly straight out to
the sides of the primary listening area, either at ear level or 1-2 feet above.

Music Only System (Model 221 LR only)
If you are setting up a music only system, begin with these general guidelines:
● The distance between your speakers should be about one-half their distance from
your favorite listening position.
● The front of the speakers should point straight at you.
● The distance from each speaker to its three closest room surfaces should be
different.
● In most rooms, you should not place your speakers in the corners.
Next, be creative Try placing your speakers along the long wall instead of the short one.
Toe the speakers in or point them straight ahead. Pull them away from the wall or push
them close. Don’t be timid. You will find that moving your speakers, even a few inches,
can greatly change their sound.
Finally, remember that the best place for your speakers is the one that satisfies you both
visually and sonically.
Cinema EQ Adjustments (Model 223 C only)
The home theater experience is best enjoyed when sounds remain consistent in tonal
balance when panned across the soundstage. For that reason, the Atlantic Technology
System 220 was designed with acoustically matching drivers.
To help achieve this goal when using front speakers from another manufacturer, we
have provided a control on the rear of the 223 C enabling you to adjust its tonal
characteristics to emulate those of your front left and right speakers.
Begin the adjustment procedure by turning the control knob to the 1 o’clock position.
This approximates the Atlantic Technology 221 LR speakers. Next, use your Dolby Pro
Logic receiver/decoder’s “test” mode to generate “hiss” from each speaker and adjust
the 223’s control for the closest match.
Although a perfect match is not usually possible, fine tuning the EQ control while
watching high quality movies will generally yield excellent results. If most of your
listening is Dolby Stereo movies, you may wish to adjust the Cinema EQ control to
compensate for the natural brightness of many movie soundtracks.
Note Some Dolby Pro Logic decoders and receivers offer a choice of “normal or
“wide-band modes for the center channel. The Model 223 C was designed to be used in
the “normal mode.

Mounting
The 221 LR and the 224 SR speakers can be mounted in a variety of ways:
On speaker stands. Atlantic Technolo y 156 ST speaker stands provide an ideal hei ht
(29" above the floor) and fit for most rooms. They are available in black or white.
On the wall. For reatest flexibility, use Atlantic Technolo y 157 WB wall brackets
with their pivotin ball-and-socket joint.
To flush mount your speakers, we have provided metal key-hole brackets. Simply place
the bracket over the oval recess on the rear of the speaker and fasten it usin the
enclosed #6 x 1" screws. Pilot holes are provided for both brackets.
For safety, please use suitably secured wall anchors (such as molly-bolts), or screws
driven into wall studs.
Note: The 224 SR speakers hang upside-down, so you will need to remo e and in ert
the grilles.
On a bookshelf. Adhesive rubber feet are included.
In the wall. The Atlantic Technolo y 254 INRF in-wall kit includes all the necessary
hardware and trim. (224 SR only)
Listening Levels and Power Handling
The power recommendation for these speaker components assumes that you will not
operate your amplifier/receiver in a way that produces distortion. Even ru ed speakers
like System 220 can be dama ed by a moderately powered system if it is producin
distortion.
If you hear a harsh or ritty noise comin from your speakers, turn down the volume.
Prolon ed or repeated operation with a distorted si nal from your amplifier/receiver
can cause dama e to your speakers that is not covered by the warranty.
Care of our Speakers
Clean your speaker cabinets usin a soft cloth and a mild, non-abrasive household
cleaner bein careful not to wet the individual drivers or the ed es of the cabinet. After
carefully removin them from the speakers, clean the rilles with warm water and a
mild dish deter ent, and dry with a soft, lint-free cloth.
Avoid placin your speakers in direct sunli ht that may, over time, fade the finish.
