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 components 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 Variable 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 performance characteristics are not designed for this purpose.
In the Atlantic Technology 220 Series of components, 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 damage to your equipment, always switch off
the amplifier or receiver when making 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 each wire end, twisting the strands
of wire together, placing the wire through one of the
post holes and screwing down the nut tightly.
It is 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 wires
in each pair is marked by either a different color, printing, ridges, or a thread intertwined with the wire strands. Conventionally, the marked wire is connected to the
red (+) terminal.

Whether your are connecting a complete System 220, or adding one speaker component to your present system, the wiring should look like the diagram in Figure 2. Before
turning on the amplifier, be certain that no stray wire strands are touching across the
two terminals as this might damage your amplifier.
Finally, check the polarity of your front speakers by listening to some music. If the
sound seems hollow, spread out and has weak bass, recheck your connections for proper
polarity and reverse the connections if necessary.
