352 PBM THX® Subwoofer Systems
Congratulations on choosing an Atlantic Technology Powered Subwoofer. This manual covers the Atlantic Technology Models 222, 262 and 352 THX® Powered Subwoofer Systems. Our subwoofers feature a proprietary amplifier and special high excursion woofers designed to deliver very high output levels on a continuous basis. The sealed acoustic suspension cabinet configuration provides extended, deep bass in a compact, room-friendly design. This new generation of subwoofers utilizes a new advanced circuit design to control distortion and woofer over-excursion. The overload circuitry incorporates optical devices that isolate this circuit from the rest of the amplifier for optimum sound quality.
Atlantic Technology Powered Subwoofers integrate easily with virtually all other brands of loudspeakers on the market. All inputs and outputs, both line level and high (speaker) level, are designed for optimum signal integrity. The premium quality gold plated connectors and all controls are clearly labeled and versatile in operation. The amplifiers have more than ample power and headroom to supply a high fidelity foundation to any audio or home theater system.
Lucasfilm Home THX
George Lucas and Lucasfilm, (creators of the Star Wars saga), originated and perfected Home THX, a strict set of standards and guidelines for home theaters, so that they may emulate the original dubbing stage. When properly followed, these guidelines address
and correct the problems of overly bright or harsh soundtracks, unintelligible dialog, limited bass response, and poor localization of sounds.
It is important to realize that THX is not a recording process or film sound format. All motion pictures will be reproduced as they were heard in the film studio dubbing
stage through the Home THX System, no matter what delivery system is used. The 352 PBM THX will easily handle the full dynamic range and low frequency bandwidth of any existing or newly emerging surround sound technology (such as Dolby AC-3). The 352 PBM THX addresses the interface requirements and dynamic capabilities of the real world. It’s combination of advanced amplification and high-excursion woofer delivers prodigious amounts of low frequency energy at high sound pressure levels with very little distortion.

Features
Your Atlantic Technology Powered Subwoofer was engineered using the latest technology and finest components available.
●High excursion drivers in a sealed acoustic suspension cabinet
●Continuous power output conservatively rated at 125, 150 and 200 watts
(Model 222, 262, and 352, respectively) Coupled with our highly efficient drivers, this is plenty of power for even the most dynamic music and effects you are likely to encounter.
●Discrete very high current output devices rated at 30 amps each
The 352 PBM THX doubles up output devices for even higher current capability.
●Working frequency range from 20Hz to low pass filter setting up to 125Hz
●Continuously adjustable low-pass filter from 60Hz to 125Hz
The slope of the low-pass filter is -24 dB/octave. This allows for flexible integration with most any brand or type of speaker on the market.
●Two line input and two passive line level outputs with gold RCA connectors
The model 352PBM THX uses one line input as the THX input to comply with THX requirements.
●All speaker inputs and outputs are gold 5-way binding posts
This is the ideal way to make connections without compromising signal integrity. All models employ a 12dB/octave subsonic filter for frequencies below 20Hz. Frequencies below 20Hz are inaudible and consume vast amounts of amplifier power. Filtering them out with a gradual slope maintains amplifier headroom while maintaining fidelity.
●Phase inverter toggle switch (0/180°)
Allows matching with many systems whose output may be inverse phased.
●Woofer output level control
Matches a wide range of input levels.
●Optical anti-clipping circuitry
This is the lowest distortion type of circuit available. It has ideal linearity, works in real time and uses imperceptible time constant triggers (delays) so that its effect during operation, if needed, is virtually instaneous and inaudible.
●75°C thermal protection
Temperature at external surface of heatsink never goes above 70°C. The output devices are rated to operate safely at much higher temperatures.
●Auto power on/off function
The 7-10 minute turn-off delay features a front panel mounted dual-color LED power indicator for power on and standby indication.

●IEC AC power socket
Unit comes with a detachable power cord. You can easily replace this cord with one of another length or plug style.
●120V or 240V AC operation
Externally switchable with an external fuse socket.
●Heavy-duty rocker-type power switch.
●Design and construction meets all UL/CSA and European safety requirements
