YSTEM

High Performance InWall Loudspeaker System

Thank you for purchasing Atlantic Technology products. Our speaker systems

have been designed to deliver exceptional sound and value. We hope you like

what you hear from them, and are happy with your decision to buy them.

Please take a few moments to read these instructions. They're intended not

only to tell you how to mount the speakers, but how to get the best perfor-

mance from them.

Important Considerations

Before Installation

Recommended Wire Sizes

The longer the wire run, the heavier the wire should be. Use the following

recommendations as a guide for your installation. And if you're in doubt,

remember that it never hurts to get the next heavier grade of wire. Also note

that lower gauge numbers equal heavier wire sizes.

Wire Run

<15 ft.

15 to 30 ft.

30 to 50 ft.

50 to 80 ft.

80 to 120 ft.

Location, Location, Location

A major determinant of any speaker's sound quality is the room and its loca-

tion in it. With in-wall speakers there are fewer placement options than with

box speakers, so giving some thought to location can really pay off. Addition-

ally, the wall your speaker is mounted in will affect its sound. Our InWall

Theater Systems have been computer designed to minimize the detrimental

effects wall mounting can have on sound, so they sound better than most, if

not all in-wall speakers.

Locations of Choice

Assuming that you'll be using System 5 speakers for more than simple back-

ground listening, here are some placement recommendations:

Stereo Systems

For stereo music reproduction the speakers are best located at approximately

ear level when seated, both on the same wall, facing the prime listening

location. A separation of approximately six to eight feet between the left and

right speakers is usually good. Ideally, the distance between the two speakers

will be the same as the distance from the speakers to the listening position.

The speakers and the listening position will then form an equilateral triangle.

There is a benefi t to mounting the speakers approximately the same distance

from the side walls, so they both create the same refl ective patterns.

Hard surfaces create lots of sound refl ections in the room while soft surfaces

tend to absorb sound. Note the speaker's location in terms of proximity to

glass and other highly sound refl ective or absorptive surfaces. A simple pair

of curtains can make a major difference in sound quality and intelligibility!

The more similar the speaker's surroundings, the more consistent the sound

will be. So placing one speaker directly adjacent to a glass wall, with the

other speaker by an open archway, will make for two dramatically different

sounding speakers.

Note that as bass frequencies refl ect within the room, some locations may be

bass heavy while other areas may be bass shy. With an external subwoofer,

changing its placement within the room may reduce these effects. But when

in-wall speakers are utilized full range, the only real option is to change the

listening position, if you end up in a diffi cult bass area.

Home Theater Systems

Today's home theater systems require you to place six or more speakers in

your room. Placement for these speakers is potentially more critical than

with pure music reproduction alone. That's because the goal of setting up

a good home theater isn't to put you in the movie theater; it's to put you

in the movie! That's right, we want you to believe you're in the jungle, the

restaurant, the offi ce, or wherever the video scene is taking place. If you keep

this goal in mind throughout the system development process you'll end up

with a better home theater, for sure.

Left/Center/Right Locations The front three speakers should be at ear

height when seated, just as with stereo speakers. Unfortunately, the presence

of the television tends to make this diffi cult, if not impossible to achieve.

(Unless you're using a front projector and a perforated screen with the center

channel speaker directly behind it). The closer you can get to this ideal the

better, however. Try to keep the left and right speakers within 3 feet to either

side of the TV screen. If possible, place the left and right speakers no more

than 2 feet above or below the height of the center channel speaker. The

center speaker itself should be centered on, and directly above or below the

TV screen.

IMPORTANT: The System 5 LCR speaker may be used in a vertical (portrait) or

horizontal (landscape) orientation.

The All Important Surround Speakers In order to achieve optimum perfor-

mance we strongly recommend Atlantic Technology Dipole or TriVector sur-

round speakers. If you are using our dedicated surround speakers please follow

the placement recommendations included in their installation instructions.

Non-Dipole Surrounds If you decide to use the System 5 LCR as a surround

speaker keep the following in mind. The more a direct radiator like the System

5 LCR is aligned with your ears, the more localizable its sound will be. And

since the vast majority of surround information consists of sonic cues that

aren't supposed to be localized, this is particularly undesirable. Generally

then, when used as a surround speaker, place the System 5 LCR on the side

or rear walls at least 2 feet above ear level, when seated.
