Congratulations on your purchase
of a Gateway®SW103/SW203/SW303 powered subwoofer. It will give your stereo system unparalleled low frequency output.
Bass frequencies are critical to realistic
sound reproduction. After you’ve hooked
up your SW103/SW203/SW303 subwoofer,
you’ll discover just how much “punch”
and depth you’ve been missing. No matter
what kind of music or videos you listen
to...whether you listen to it loud or soft,
you’ll experience sound that’s richer and
fuller. Bass guitar and string bass will
have more impact. You’ll be able to FEEL
as well as hear percussion – just the way
you would at a live performance. If you
have an audio/video system, movies will
come alive with thunderous sound effects
that were never possible without the
SW103/SW203/SW303.
The SW103/SW203/SW303 is a self-pow-
ered subwoofer that frees your receiver or
power amplifier from the power demands
of reproducing very low frequencies. To
do this, the SW103/SW203/SW303 incorporates its own built-in crossover system
that automatically “assigns” higher frequencies to your main speakers and lower
frequencies to its own power amplifier,
contained within the subwoofer enclosure.
The SW103/SW203/SW303 has been
meticulously designed and tested to insure
high performance, durability and longevity.
This manual is designed to take you
step-by-step through the setup and
operating process. This procedure is not
difficult, but it IS slightly different than
setting up a line level component such as
a cassette deck or CD player. Reading this
manual carefully will insure that you get
maximum performance from your
SW103/SW203/SW303.
A
UNPACKING
Remove the SW103/SW203/SW303 from
its packing carefully and inspect it for any
shipping damage. If you discover damage,
contact your Gateway®dealer immediately.
If possible, save the carton and internal
packing. It’s the best possible protection
for your SW103/SW203/SW303 if you
need to move it or return it for service.
Keep your sales receipt in a secure
place. It helps establish the duration of
your warranty and is good for insurance
purposes (just in case anything happens
to your stereo system).

1. POWER INDICATOR. When the amplifier
is ON, this indicator will be green. When the
amplifier is in the STANDBY mode, this indicator will be red.
2. VOLUME CONTROL. Rotating this knob
clockwise increases the output level of the
subwoofer. To start out, make sure that the
VOLUME is turned all the way down (fully
counterclockwise). Later, after some initial
listening tests, you can adjust the volume to
your own tastes. However, care should be
taken not to overdrive the subwoofer to the
point of audible distortion.
3. SUB IN. This connection is used to connect
to the subwoofer line output of your receiver.

4. REMOVABLE FUSE HOLDER. By pushing
in and turning counter-clockwise, you can
remove and replace the fuse. Check the rating
on the fuse for proper size of your unit.
