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 speak-
ers 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 compen-
sate 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)
Meets all current UL/CSA and European safety requirements
THX Ultra Certified (SA-700 only)
THX is a group of performance standards and technologies devel-
oped 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 digi-
tal 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 ref-
erence, as they indicate that these systems must deliver a minimum
level of performance in the specified area.
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.
