Instruction Manual
■Adjustable (50 Hz to 150 Hz)
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)

THX Ultra Certified
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
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.

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.
