User`s manual

You should set the crossover frequency to obtain a smooth and
seamless transition from the subwoofertothe main speakers
in your
system. If your main speakers are smaller units with limited low
frequency output, you may wish to choose a higherfrequency (such
as 100-120 Hz) than you would with larger speakers which have
greater low frequency output. With larger speakers, you might start
with this control set lower, such as 80 Hz.
Subwoofer Direct
Subwoofer Direct is a setting on the low-pass crossover knob and
will allow frequencies up to 200 Hz into the subwoofer. See below
for a more detailed explanation of this feature.
Speaker Level Output/Line Level Output
When connected in this fashion, your satellite speakers will be
crossed over at 80 Hz. This removes the lower bass from your
satellites, enabling them to do a better job reproducing high
frequencies and giving your receiver's amp more headroom (up to
50% more power).
You may also connect your satellites directly to your receiver or
amplifier along with the subwoofer if you wish to bypass this
crossover.
Caution!!!
To avoiddamage to yourmain amplifier, be sure to maintain correct
polarity when making
all connections. Red (positive) to red, and
black(negative) to black. Be sure thatall connections are tight, and
that there are no loose strands or frayed wires.
Power Switch
The masterpower switch is located on the lower right half of the unit.
This rocker style switch is the main on/off for the unit. This switch
should be set to position 1 for on (up), 0 for off (down).

full range audio signal for input when using the built-in crossover
(controlled
by the dial on the back panel). Many home theater
processors/receivers (Dolby
Digital®, DTS®, THX®) have a "subwoofer
