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.

Phase Switch
This switch allows precise acoustic matching with satellite speaker
systems whose output may be phase reversed. Try in both the

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.
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.
High Level Input
If your electronics do not have a line-level sub out, connect the LeftRight speaker terminals of your electronics to these connections.
Set the SB-900’s crossover to “Lowpass,” and adjust accordingly.
Low-Pass Control
An adjustable (55Hz to 200Hz) @ 18dB per octave low-pass
crossover.

Placement and Operation
Generally speaking, the best location PHASE
for your new subwoofer is the
front of the room, close to a corner
(Figure 5).
Every room has its own

LEVEL
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 moreAUTO

you will hear. However, in some rooms,
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.
Using the Subwoofer Low-Pass Control

ensuring that the subwoofer and satellites
produce a cohesive and well integrated sound “picture.”
LOWPASS
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 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.
