Features
PedWoofer Modules
Ultra-long-throw 12" (8200) or 10" (6200) woofer with continu-
ous concave cone formulated from homopolymer, mica, micro-
glass spheres, carbon fi bers, and ceramics
The woofer’s damped surround is a half roll rubber type which allows
for very long, linear travel of the cone. Its spider is injection molded
from a man-made rubber compound that remains consistent in per-
formance over the lifetime of the driver without any degradation due
to age, heat, or use.
2.5" (8200) or 2" (6200) 4-layer voice coil drives the cone along
with a 12 lbs. (8200) or 10 lbs. (6200) vented magnet structure
This assembly includes a “T” shaped pole piece and Faraday shorting
ring that reduces 2

over standard woofers.
Massive, sealed enclosures for low distortion deep bass output
Sealed woofers are inherently lower in distortion and naturally deliver
deep, smooth bass response, with a gradual and predictable roll-off
below resonance, ensuring accurate musical bass reproduction along
with terrifi c special effects. The 8200 PedWoofer enclosure’s 1-inch
thick sides, 3⁄4-inch thick front and rear, combined with extensive
internal bracing result in reduced enclosure resonances and lower
distortion. The 6200 PedWoofer enclosure is identical except it has
3⁄4-inch thick sides.
SA-6200 and SA-8200
Linear power high current discrete amplifi ers conservatively
rated at 350 watts RMS per channel with short-term peak out-
put ability in excess of 550 watts per channel
The fully discrete design utilizes audiophile grade component parts
including an independent power supply for each channel with its own
custom-wound, low-hum Toroid transformer. The SA-8200 is a two-
channel amplifi er and the SA-6200 is a single channel unit.
Servo-control circuitry
This circuit monitors and corrects for anomalies in the woofer’s per-
formance. If the servo-circuit detects driver distortion, it immediately
sends out a corrective signal to eliminate it, resulting in very high out-
put levels at unusually low distortion levels.
Built-in Parametric Equalizer (pages 5 and 13)
Designed to fl atten and smooth bass response deviations caused by
standing waves at the listening position, in your room. The amplifi ers
have a single band of parametric EQ for each channel.
Four Built-in Program Equalizations with Reference
setting (pages 7 and 14)
We’ve carefully chosen and built in 4 preset bass EQ curves, plus a
fl at/THX response setting, to enhance your enjoyment of all program
materials.
Wireless Remote Operation (pages 7 and 14)
Control the program EQs, volume trim adjustment, and subwoofer
muting from your easy chair.
A useful in-room working frequency range of 20 Hz to 150Hz
Adjustable (50 Hz to 150 Hz) low-pass crossover (@ 18dB 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. Can 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 click-
stop 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)
Rack Mountable
Meets all current UL/CSA and European safety requirements
THX Ultra 2 Certifi ed (SA-8200)
THX is a group of performance standards and technologies initially
developed by Lucasfi lm 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 fi nal pro-
duction mix down of the fi lm. 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.
For more information, see
the THX website at www.thx.com.
THX Ultra 2 standards are based upon a room size of 3000 cubic feet
(LxWxH). This doesn’t mean certifi ed components must be used in
rooms this exact size. The room sizes simply provide a frame of refer-
ence, as they indicate that these systems must deliver a minimum level
of performance in the specifi ed area. System 8200 requires 2 pairs of
PedWoofers to qualify for Ultra 2 certifi cation.
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, expla-
nations of how sound spreads in a room, information about home theater
setup, a glossary, and even an explanation of how standing waves “set up”
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.
