SBT-1000 & SBT-500 Powered Subwoofers
EQ
–
Max SPL or Max Range
The Max SPL position provides stronger overall output
with restricted very deep bass output. The Max Range
position provides deeper bass extension with restricted
maximum overall output.
Low Pass
NORMAL
position: The Low Pass control sets the
upper frequency limit of the subwoofer.
BYPASS
posi-
tion: For a THX sub output signal or another external
signal source with its own low pass equalization.
Standby Switch
OFF
position: The subwoofer is OFF.
ON position: The subwoofer is ON.
AUTO
position: The subwoofer turns on in response to
an audio signal. It turns off after a period of silence.
Phase Switch
Set for stronger output in the narrow frequency range
covered by both the satellites and the subwoofer.
Volume
Sets the overall output of the subwoofer.
Crossover Frequency (Low Pass)
Sets the upper frequency limit of the subwoofer.
Line In
Left and Right channel RCA jacks for connecting the
stereo or mono subwoofer signal output of a preamp/
receiver or other signal source.
XLR inputs
These jacks accept XLR signal cables, which provide
greater resistance to the intrusion of hum or noise over
long signal cable lengths.
110/220V Switch
Voltage switch for use in different countries. This
switch will be set when you receive the unit. Change
this setting only when you are sure your application
requires it. For US, the switch should be set to the 110-
120V position.
Main Power
Set to OFF if the subwoofer is not going to be used for
an extended period of time (more than two to three
weeks).
AC Power Input
Use the included power cord to connect your amplifier
to a wall outlet.

Features
Your Atlantic Technology powered subwoofer has
been engineered using the latest technology and
finest components available.
·
Dual
long-throw composite cone bass drivers,
each with a vented motor structure and high
temperature, 4-layer voice coil.
This powerful driver design has a very stiff cone that
acts like a piston throughout its operating range. Its
massive magnetic motor assembly and high tempera-
ture component parts deliver exceptional performance
and reliability.
·
The sturdy enclosure design delivers low
distortion and extended deep bass output.
As with all Atlantic Technology subwoofers, we have
paid close attention to providing accurate musical bass
reproduction along with terrific special effects.
·
High-efficiency 500 and 1000 watt amplifiers.
The output stages are capable of very high current
delivery for exceptional driver control. The digital
design ensures cool operation. Each amplifier has
been precision matched and equalized to its specific
driver. The result is powerful, controlled bass with
great articulation and authority.
·
An adjustable (40Hz to 140Hz) @ 24dB per
octave low pass crossover.
The steep 24dB per octave slope allows for much better
blending with the satellite speakers while making the
woofer less localizable.
Note: If you are using a surround processor or receiver
that includes its own low-pass subwoofer output (or a
THX-certified processor/receiver), set the subwoofer
crossover control to the Bypass position.
·
A Phase Invert switch (normal/invert).
This switch allows better acoustic matching with satellite
speaker systems. Be sure to try the Phase switch in both
positions when you set up your subwoofer. If you hear
increased bass output in one position, leave the switch in
that position.
·
Automatic standby operation
The
Automatic Standby function features signal sens-
ing turn-on with 7-10 minute turn-off delay. A switch
allows your choice of "Always On" or "Automatic
Standby-Off" positions.
