Installation of the 8 SUB Woofer Module is covered separately by an instruction sheet included with the woofer. IN Atlantic Technology® NOVATIVE H OME T HEATER 2 Safety Precautions InWall Subwoofer System IMPORTANT NOTE 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 should never attempt to use a different amplifier with these woofers or different woofers with these amplifiers. Features 8 SUB Woofer s 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! s Sealed enclosure design provides for low distortion deep bass output Safety Precautions 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 s 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. 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. s 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. s Built-in Parametric Equalizer (pages 5 and 13) For Future Reference Record your speaker and amplifier serial numbers and date of purchase here: Model Number Designed to flatten and smooth bass response deviations caused by standing waves at the listening position in your room. s 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 . s Serial Number Wireless Remote Operation (pages 7 and 14) Date of Purchase Control program EQs, volume trim adjustment, and full subwoofer muting from your listening position. s The serial number is found on the back of the speaker near the connecting terminals.

(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. 12 12 12 13 13 13 14 14 14 14 14 15 15 15 16 The LOW PASS Control Bass Management The PHASE Control Parametric Room Equalizer (EQ) Adjusting the Parametric EQ Using a Meter or Real Time Analyzer (RTA) Level Setting Using an SPL Meter Level Setting Setup Without Using an SPL Meter Setting the Subwoofer Level Without an SPL Meter or Test Tones How Much is Enough?

(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. Copyright © 2001 Atlantic Technology International.
