High Performance THX Home Theater Loudspeaker System

Congratulations on your purchase of the Atlantic Technology System 370 THX loudspeaker system. With proper care, your new speaker system will provide many years of trouble-free, high quality sound reproduction.

The System 370 THX was designed to provide accurate, uncompromised reproduction of high fidelity music and movie soundtracks. Nothing was spared in the development of the speaker components and cabinetry to provide superior performance, while maintaining an elegant, compact design that is easily integrated into the home.

What Is Home THX?

1. A need to correct the audible tonal and spatial errors caused by the reproduction of movie soundtracks designed for playback in large theaters in the smaller environment of the home.

2. A need to more accurately reproduce the complex and competing soundfields present in multichannel soundtracks.

370 THX

A Home THX audio system is the ultimate in sound for multi-channel home theater systems. The system incorporates a series of patented electronic and loudspeaker developments designed to reproduce all multi-channel sources accurately in the home environment. The driving force behind the creation of Home THX was the observation that, in the home environment, conventional audio components could not accurately reproduce soundtracks as they were originally intended. Two basic requirements were identified:

Why THX Loudspeakers?

Conventional high fidelity loudspeakers, even very expensive ones, are not ideally suited to the demands of multi-channel soundtracks. The Atlantic Technology System 370 THX is ideally suited to the accurate reproduction of high fidelity music and multi-channel sound. Here’s why:

A Word About Digital Surround Technologies and THX

It is important to remember that THX technologies work in conjunction with whatever processing technology it is paired. THX, on its own, is not a decoder or processor. It enhances and adapts the surround sound processor it is paired with to more accurately reproduce movie soundtracks in the home environment.

The new digital surround technologies, such as Dolby Digital improvements in channel separation and dynamic range over conventional multi-channel analog matrix formats such as Dolby Surround

and Dolby Pro Logic®. THX sound systems, with their

(AC-3®) and DTS®, offer dramatic

outstanding dynamic, spatial, and tonal performance, are ideally suited to convey the benefits of digital multi-channel formats. THX technologies will continue to be essential for the accurate reproduction of all multi-channel sources, both now, and in the future.

Connection

We recommend that you connect your new System 370 THX speaker components using high quality wire of 16 gauge or larger. There are many respected manufacturers in the audio industry that specialize in speaker wire and interconnect cables who make suitable products for your new system. We recommend that you consult your local audio/video specialist for more specific information.

Warning: To prevent risk of electrical shock or damage to your equipment, always unplug all component AC cords before proceeding with speaker and component connections! The last step in wiring your system is plugging in the AC cords!

You can connect your System 370 THX speakers by using a variety of 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. We recommend that you check your local electrical codes to make sure you are not using an improper connector.

one speaker or subwoofer to your present system, the wiring should usually look like the diagram in Figure 2. When installing an Atlantic Technology subwoofer into your system, refer to the subwoofer’s instruction manual for other wiring options. Before turning on the amplifier, be certain that no stray wire strands are touching across the two terminals as this might damage your amplifier.

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. By convention, the marked wire is connected to the red (+) terminal.
