Model 4.5 SR Surround Speaker
The Model 4.5 SR Surround Speaker is intended for use in audio/video sound systems with dedicated
surround channel speakers. Each speaker has two 3 1/2" IMG woofers, as well as two 3/4" fabric dome
tweeters which are angled and phased to produce ambience without localization. Its wide bandwidth
and unique construction makes it especially suitable for Dolby Digital and DTS applications. Please
note that there is a dedicated LEFT and RIGHT model 4.5 SR. This is clearly marked on the back of
each speaker.
Note:
The 4.5 SR is not intended for use as a regular right and left front channel stereo speaker or satellite.
Its spatial performance characteristics are simply not appropriate for this purpose. In the Atlantic Technology
4.5 Series of components, the Model 4.5 LR fills this role.
Although the speakers in the Atlantic Technology System 4.5 are acoustically and cosmetically
matched to each other for best results, they may also be used with a wide variety of speakers from
other manufacturers with satisfying results.
Connecting Your System
We recommend that you connect your System 4.5 speaker systems with high quality dual conductor
stranded wire of 18 gauge or larger, for lengths up to 25 feet. Use 16 gauge dual conductor or larger for
longer runs of wire. Contact your local audio/video specialist for specific cable recommendations and
further information for special circumstances.
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 4.5 speakers by using a variety of audio connectors, or you can:
1.
Remove 1/2" of insulation from each wire end.
2.
Twist the stranded wire together, keeping the two ends separate.
3.
Place the appropriate wire through the appropriate postholes in the connectors. These holes are
revealed when you loosen the connector thumbscrew.
4.
Screw down the thumbscrew tightly.
We recommend that you check your local electrical codes to make sure that you are not using an
improper connector.
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 conductors of each pair is
marked by a different color, printing, ridges, or a thread intertwined
with the wire strands. By convention, the marked wire is connected
to the red (+) terminal.
Whether your are connecting a complete System 4.5, or adding a single speaker component to your
present system, the wiring should look like the diagram in Figure 2.
