370 IN-SR

THX Certified On-Wall/In-Wall Dipole Surround Speaker

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

optimized for use with any multi-channel sound format including Dolby Surround

, 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.

t 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.

Warning: Before turning on the amplifier, be certain that no stray wire strands are touching across the two

terminals as this might damage your amplifier.

Home Theater

Please note that the primary goal of a good home theater is not to make you believe that you are in a

movie theater. It’s to make you believe you are in the scene taking place on the screen.

Note: Most discrete digital home theater systems allow you to select between “Small” and “Large” surround

speakers. Since the 370 IN-SR is a THX certified speaker it has been designed only to work with a subwoofer

used to reproduce frequencies below 80 Hz. Therefore, please set the processor for “Small” surround speakers.

Surround Effects

The 370 IN-SR’s size, shape, and unique ability to mount on, or recessed within, a standard wall

significantly increases its placement flexibility and dramatically reduces its visual room intrusion. The

result is greater flexibility in placement than the vast majority of conventional surround loudspeakers.

Installation instructions for the 370 IN-SR are detailed on the enclosed cardboard mounting template.

Due to the 370 IN-SR’s dipole spatial characteristics, it is possible to place the speakers in a number of

locations, but usually the best location is straight out to the sides of, or slightly behind the primary

listening area, approximately 1-2 feet above ear level.

Note: Since the surround speakers are intended to re-create the ambient sounds taking place in the movie scene

you may not be directly aware of their presence for much of the movie. This is because the signal they receive is

almost overwhelmingly subtle sounds that are intended to make you believe you’re “where the action is.”

Mounting

Note:

In-wall installation instructions for the 370 IN-SR are detailed on the enclosed cardboard mounting

template.

The orientation of the 370 IN-SR’s is important to the proper generation of an involving and diffuse

surround effect. Mount each speaker on the wall or within a wall so that the “direct” soundfield is aimed

toward the front of the room, and the “ambient” soundfield is directed toward the rear. To insure this

orientation, make sure that the RIGHT speaker is on the right side wall of the room, and the LEFT speaker

is on the left side wall of the room. The speakers are marked RIGHT and LEFT on the back.

Models 4.5 LR, 4.5 C, and 4.5 SR

To mount your speakers on a wall, we have installed metal key-hole brackets on the back of the 370

IN-SR. Be sure to use a strong screw whose head and shaft will fit within the keyhole opening and slot.

Also be sure to drive the screw well into a stud or use a mounting device (such as a molly-bolt) that is

capable of holding the weight of the speaker. Never simply drive a nail or screw into sheet rock or

other wall materials. Always follow the above guidelines for safe speaker mounting.

For greatest flexibility, you can use pivoting ball-and-socket wall brackets of suitable weight rating

(e.g., Omnimount 50 Series, Vogel, etc.), usually available from your audio/video retailer. These can be

connected to the 370 IN-SR using the 1/4x20 threaded insert in the back of the cabinet.

Again, for safety, please use suitably secured wall anchors (such as molly-bolts), or screws driven into

wall studs.

Care and Feeding of Your Speakers

Clean your speaker cabinets using a soft cloth moistened with a mild, non-abrasive glass cleaner, being

careful not to wet the edges of the cabinet. Also, be careful not to get any cleaning fluids on the driver

cones or domes. It may be best to dampen the cloth with the cleaner and then wipe the speakers. After

carefully removing the grilles from the speakers by pulling them forward, clean them with a quick pass

from a vacuum cleaner using a soft brush attachment. This should remove any dust accumulation. Avoid

placing your speakers in direct sunlight or near a source of heat that may, over time, damage the finish.

Important: Save Your Boxes! If you can, save the cartons, packing pieces, and plastic bags that came with your

speakers. They’ll be useful in case you move or have to ship your loudspeakers for any reason. In any case, save

all packing materials until you are certain that the systems have suffered no damage in shipment. If you find

such damage, either visible or internal, contact your dealer immediately for the proper return procedure.
