SP-8000 Features
Built-in Parametric Equalizer (pages 5 and 13)
Designed to atten and smooth bass response deviations caused by
standing waves at the listening position, in your room.
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
at/THX response setting, to enhance your enjoyment of all program
materials.
Wireless Remote Operation (pages 7, 12 and 13)
Control the program EQs, volume trim adjustment, and subwoofer
muting from your easy chair.
Adjustable (50 Hz to 150 Hz) low-pass crossover (@ 18dB per
octave) with a THX/External setting (page 10)
Allows for much better bass integration with the satellite speakers
while making the woofer less localizable.
Low level inputs, low level outputs, balanced and unbalanced
(pages 6, 8 and 9)
Easily solves compatability issues between balanced and unbalanced
components.
Four position Phase Invert switch (pages 5, 11 and 12)
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 bass at
the listening position.
A convenient front panel mounted Level Control with a click-
stop THX/REF input sensitivity setting (pages 5 and 12)
Meets all current UL/CSA and European safety requirements
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 system’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 awoofer level in your system.
