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, with in an equilateral
triangle, is intended to alert the user to the presence of
uninsu lated “dangerous voltage” within the product’s
enclosure that may be of sufficient magnitude to con-
stitute 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.

When in the NORMAL 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. (pages 5 and 9)

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.

Many surround sound receivers and processors offer a choice of crossovers, typically between 80 Hz and 120 Hz. If yours does, we recommend
using the 100Hz setting when using small speakers such as those in the
System 1200 or 2200. Consult your electronics owner's manual for more
details.
Higher crossover frequencies pass more bass but can sound boomy
and may be more easily localized to the subwoofer. Higher crossover
frequencies may be suitable, however, when using very small satellites
that have no real low frequency performance. Settings lower than 80Hz
should be employed if you are using larger speakers that have extended
bass response. This way, the subwoofer will only reproduce the very lowest bass frequencies that are in the range where the large main speakers
begin to roll off.
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
Using the Subwoofer Crossover Control
satellites produce a cohesive and well integrated sound “picture.”
Subwoofer Troubleshooting Guide
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.

Your subwoofer is constructed from 3/4” Medium Density Fiberboard.
MDF is a non-resonant material ideal for speaker system enclosures. To
clean the cabinet you 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 heat that may, over time, damage the finish.
When used with the System 1200 or 2200,
the Crossover control should be set at
around 100Hz unless you are using a processor with its own built-in crossover. The
goal is to optimize the performance of the
system by ensuring that the subwoofer and
