Safety Precautions

IMPORTANT NOTE

InWall Subwoofer System

Features

These instructions are for Atlantic Technology InWall Subwoofer systems using the SA-350 Mono and SA-700 Dual Mono Subwoofer amplifiers. All instructions and information pertain to both systems. Note that the SA-350 amplifier only has one set of front mounted controls and one set of input/output connectors on the back and is designed to work with a single 8 SUB woofer module.

The unique design of these drivers and amplifiers means that they must only be used together, with each other. You sh ou l d

never attempt to use a different amplifier with these woofers or different woofers with these amplifiers.

Safety Precautions

CAUTION: To reduce the risk of electric shock, do not remove

the cover (or back). No user serviceable parts inside. Refer to qualified personnel.

WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture.

The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within

the product’s enclosure that may be of sufficient magnitude to constitute a risk of electrical shock to persons.

The exclamation point within an equilateral triangle

is intended to alert the user to the presence of important operating maintenance (servicing) instructions in the literature accompanying the appliance.

8 SUB Woofer

■

Ultra-long-throw 8" Coated Composite Molded Graphite polymer cone drivers with vented 8 pound motor structure and 1-3/4" high temperature, 4 layer voice coil

A massive magnetic motor assembly and high temperature parts combined with a bumped out rear plate and compliant suspension allow very long travel capability for the cone. The result is amazing bass performance from a relatively small footprint. One of the most powerful 8" subwoofer drivers ever designed, the motor assembly is much more consistent with 15" woofers!

■

Sealed enclosure design provides for low distortion deep bass output

This design is inherently low in distortion and naturally delivers deep, smooth bass response with a gradual and predictable rolloff below resonance, ensuring accurate musical bass reproduction along with terrific special effects.

SA-350 and SA-700

■

Linear power high current discrete Class G amplifier conservatively rated at 350 watts RMS per channel with short term peak output ability in excess of 550 watts

The fully discrete design utilizes audiophile grade component parts including an independent power supply for each channel with its own custom-wound, low-hum Toroidal transformer. Class G design means each of the power supplies is dual mode in operation, one for long term operation and the second for short term very high power peaks. High peak current delivers exceptional driver control.

■

Servo-control circuitry

This circuit monitors woofer performance. If the servo-control detects driver distortion it immediately regains control and eliminates it, resulting in very high output levels at unusually low distortion levels.

■

Built-in Parametric Equalizer (pages 5 and 13)

Designed to flatten and smooth bass response deviations caused by standing waves at the listening position in your room.

■

Four Built-in Program Equalization and one Reference setting (pages 7 and 14)

We’ve carefully chosen and built in several preset bass EQ curves, plus a flat/THX response setting, to enhance your enjoyment of all program materials .

■

Wireless Remote Operation (pages 7 and 14)

Control program EQs, volume trim adjustment, and full subwoofer muting from your listening position.

■

A useful in room working frequency range of 20 Hz to 150Hz

Instruction Manual

■

Adjustable (50 Hz to 150 Hz) low-pass crossover (@ 24 dB per octave) with a THX/External setting (pages 5, 12 and 14)

Allows for much better bass integration with the satellite speakers while making the woofer less localizable.

■

Low level inputs, low level thruputs (pages 6 and 7)

Thruputs allow daisy chaining of multiple subwoofers, or can act as a return path back to the processor.

■

Four position Phase Invert switch (pages 5, 12 and 14)

Allows precise acoustic matching with satellite speaker systems whose output may be phase reversed. May also help to compensate for unusual room acoustics that can occur, causing a lack of or too much bass at the listening position.

■

A convenient front panel mounted Level Control with a clickstop THX/REF input sensitivity setting (pages 5 and 14)

■

Automatic standby operation with LED indicator (page 12)

Features signal sensing turn-on with 7-10 minute turn-off delay.

■

Heavy-Duty detachable AC power cord and input socket (pages 6 and 12)

■

Meets all current UL/CSA and European safety requirements

THX Ultra Certified (SA-700 only)

THX is a group of performance standards and technologies developed by Lucasfilm Ltd. (of Star Wars fame). These are intended to ensure that what you hear (and see) on your home system, as closely as possible, matches what the director heard and saw during the final production mixdown of the film. THX is intended to enhance all surround formats including the latest discrete multi-channel digital types. Please note that THX is not a surround format itself.

THX Ultra standards are based upon a room size of 3000 cubic feet (LxWxH). This doesn’t mean certified components must be used in rooms this exact size. The room sizes simply provide a frame of reference, as they indicate that these systems must deliver a minimum level of performance in the specified area.

Introduction

Test and Training CD-ROM

The enclosed Atlantic Technology/Sencore Test and Training Disc includes lots of useful information. (Sencore is a world famous manufacturer of electronic test and measurement equipment. We strongly support the use of this caliber of equipment in the setup of home surround sound systems.) Please take a moment to go over its contents before proceeding with your woofer’s setup. The disc includes room mode calculators, explanations of how sound spreads in a room, information about home theater setup, a glossary, and even an explanation of how standing waves “setup” in rooms. Most importantly, there are test tones on the disc intended to be used to set the equalizer and subwoofer level in your system.

Specifications are those in effect at the time of printing. Atlantic Technology reserves the right to change specifications or designs at any time without notice.

InWall Subwoofer Systems

InWall Subwoofer System

Congratulations on your purchase of an Atlantic Technology InWall Subwoofer System. This unique “invisible subwoofer” will enhance your listening pleasure dramatically, by providing the bass foundation upon which most music and special effects are built. In addition, its flexible control capability brings new meaning to the terms system and room integration, providing unheard of fine tuning capability to optimize its performance and your enjoyment.

The InWall Subwoofer System is capable of delivering very high output levels and wide dynamic range. When properly set up and adjusted it will provide smooth in-room bass response down to approximately 25 Hz, with a peak SPL capability in excess of 105dB (using two dual woofer modules and the SA-700 amplifier, in a 3000 cubic foot space).

Figure 1

Figure 2 Figure 3

The system consists of in-wall enclosures (Fig. 1) designed to be installed in your walls before the sheetrock is put up, a dual 8 inch woofer driver assembly (Fig. 2) and a separate dedicated amplifier and remote control (Fig. 3-4) to power the woofers. There are two versions of the system, a single sub assembly paired with an SA-350 mono amplifier and two subwoofer assemblies paired with the SA700 dual mono amplifier. The combination two subwoofer assembly/SA-700 system is THX Ultra certified.

Your Atlantic Technology powered subwoofer is designed to smoothly integrate with virtually all other brands of loudspeakers on the market. And from its premium gold plated connectors to its very flexible range of adjustment, this is one of the most versatile and unique high performance subwoofers ever produced.
