Thank you for choosing Atlantic Technology home theater products. Your new speaker system is
precision crafted to give you years of enjoyable, trouble free service. This manual covers the Atlantic
Technology 370 IN-SR Dipole On-wall/In-wall Surround speaker. This unique speaker has been

, Dolby Pro-Logic

,
Dolby Digital 5.1
®
and DTS
®

The Model 370 IN-SR Surround Speaker is intended for use in audio/video sound systems with
dedicated surround channel speakers. Each speaker has two 5-1/4" CCMG (Coated Composite Molded
Graphite) 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 370 IN-SR. This is clearly marked on the back of each speaker.
Note: The 370 IN-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. This speaker will
work with any number of home theater systems including, but not limited to, Atlantic Technology Systems
450 THX, 370 THX, 270, and 4.5. As a THX certified Dipole surround the 370 IN-SR may be used with any
THX certified or non-THX certified system. Although the speakers in Atlantic Technology Systems 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 speakers 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 audio/video dealer 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 370 IN-SR 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.
