Safety Precautions
CAUTION: To reduce the risk of electric shock, do not remove the
cover (or back). No user serviceable parts inside. Refer to qualified personnel.
WARNING: To reduce the risk of fire or electric shock, do not expose
this appliance to rain or moisture. This device generates a fair amount of
heat. Make sure nothing blocks the ventilation openings on the top and
bottom of the unit.
The lightning flash with arrowhead, with­in an equilateral
triangle, is intended to alert the user to the presence of
uninsu­lated “dangerous voltage” within the product’s
enclosure that may be of sufficient magnitude to constitute a risk of electrical shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating maintenance (servicing) instructions in the
literature accompanying the appliance.

Voltage Select 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 115V position.
Phase Switch
This switch allows precise acoustic matching with satellite speaker
systems whose output may be phase reversed. Try in both positions — use the position that results in the strongest bass output.

Low Level Input
Use the input to connect to the subwoofer or LFE line out from
your processor/receiver.
Low-Pass Control
An adjustable (55Hz to 200Hz) @ 18dB per octave low-pass
crossover.

Standby Switch
When in ON position, the amplifier will always be on. When in the
AUTO position, the amplifier will be in Automatic Standby Mode.
Low Level Output
The outputs allow daisy chaining of multiple subwoofers, or as a
return path back to the processor.
Use this control to set the level of bass desired
Low-Pass Switch

When in the LOW-PASS position, adjustment of the crossover can
be made by the Crossover Control. If being fed a pre-filtered or THX
signal, place the switch at the BYPASS position.

On/Off Switch
Use this switch to turn the amplifier completely on or off.
AC Input
Use the included power cord to connect your amplifier to a wall
outlet.

Placement and Operation
Generally speaking, the best location for your new subwoofer is the
front of the room, close to a corner (Figure 5). Every room has its own
unique sound characteristics, and flexibility in the exact placement of
the subwoofer is always desirable. The closer the subwoofer is placed to
a wall and especially a corner, the more and deeper the bass response
you will hear. However, in some rooms, corner placement can produce a
“one note” boomy effect. Under such circumstances the subwoofer may
work better away from the corner. Experiment to find the best position
in your room.

STANDBY
Most surround sound receivers and processors offer a choice of crossLOW-PASS BYPASS
overs, typically between 60 Hz and 150 Hz. We recommend using the
100Hz setting when using small speakers such as those in the FS-7.0.
Consult your electronics owner's manual for more details.
It’s generally undesirable to have the main speakers and the subwoofer
overlap too much. Larger speakers means a lower Low-pass crossover
frequency, smaller speakers means a higher Low-pass crossover frequency. Consult the manufacturer’s specified low frequency response
for your main speakers to determine the appropriate Low-pass setting
on your subwoofer. In the end, however, a little time spent experimenting
will generally result in dramatically better bass response.
Care of Your Subwoofer
Your subwoofer is constructed from 5/8” Medium Density Fiberboard.
MDF is a non-resonant material ideal for speaker system enclosures. To
clean the cabinet you ON
may use a soft cloth either dry or slightly dampened
with clean water. Be careful not to wet the cabinet or allow any water to

enter the cabinet seams. Avoid placing your speakers in direct sunlight
or
near a source of heatOFF
that may, over time, damage the finish. SB-800-BLK Powered Subwoofe

Subwoofer Troubleshooting Guide
DOUBLE INSULATION - WHEN SERVIC
USE ONLY IDENTICAL REPLACEMENT P
Once your subwoofer is set up, you should have many years of maintenance free enjoyment from your system. However, if you should encounter a problem, refer to the following guide to help you find the solution. If a problem persists, you should contact your local authorized Atlantic
Technology dealer.
FOR 110-120VAC, USE T1.0AL 250V FUSE
Problem
Possible Cause
No bass output
AC power cord unplugged or plugged into a non-working outlet.
Plug into a working outlet.
Input cables not securely connected or defective.
Check all connections, then try another
input cable.
Audible buzz or hum Input cable not securely connected or defective.
Check all connections, then try another
input cable.
Ground loop through antenna or cable TV system input.
FOR 220-240VAC,
USE T1.6AL
250V FUSE
Possible
Solution
Test by disconnecting antenna and/or cable
system input leads. If hum goes away, install
isolation balun(s) at that point.
