UNPACKING
PLACEMENT
Carefully remove your new Gateway®
speakers from their boxes, avoiding staples
which can cause damage to the cabinets.
Inspect each speaker for transit damage.
If you discover damage, contact Gateway®
immediately.
Positioning Your
Subwoofer
Refer to Figure 1 for satellite speaker
placement. Front channel speakers
should be placed at least 6 feet apart to
create proper stereo imaging. The rear
channel surround speakers should be
positioned behind and slightly to the
sides of the viewer/listener. The rear cen-
ter speaker should be positioned at the

Save your cartons – they are the best
possible protection for your speakers
should you ever have a need to move them.

may take some experimentation with different
locations for the surround speakers to suit
your preference and your room. The center

See Figure 3. The metal bracket supplied on the
rear of each satellite can be removed and an
aftermarket swivel-type satellite mount can be
used. Your Gateway® satellite speaker will

and other manufacturers’ mounts. Follow
the instructions included with the mount for

Refer to Figure 4 for proper connection.
Use the supplied male RCA to RCA line
level cable to connect the subwoofer to the
receiver. The satellites connect to the
receiver as shown with the red/black wires
supplied. Be sure to maintain proper
polarity when connecting the satellites and

You can leave the SW103 in the ON mode,

not draw much power in this state and
will be ready to add low bass the moment
you begin to play music. The SW103,

utes, when no music is playing.
o 6. Some digital receivers only send a
subwoofer out signal when playing a
DVD or movie in the digital mode. In
the 2-channel (stereo music) mode,
no subwoofer out signal is sent to the
subwoofer. You may need to set your
main speakers to “small” mode in
your receiver setup to get the receiver’s
subwoofer out to turn on. Check
Caring for Your
Gateway® Speakers
The subwoofer and satellite cabinets are
finished with a very high quality polymer
laminate covering that is both attractive
and serves as an excellent protection for
the wood cabinet. The system can be
cleaned with a damp, soft cloth or you
may use a high-quality furniture polish to
maintain the original luster.
your receiver’s owner’s manual for
setup and subwoofer operation.
However, if you’re not using your stereo
system for a long period of time (such as
when you’re on vacation), unplug the
subwoofer from the 120 volt AC wall plug.
o 7. Adjust the subwoofer’s VOLUME control
until you are satisfied with the amount
of bass. You may want to try several
different tapes, compact discs or DVDs
while determining how high to adjust
the subwoofer VOLUME. The amount
of bass varies from disc to disc and
between different types of music.
A Word About
Power Handling
Remember, most amplifiers put out their
full rated power well before the volume
control is turned all the way up!
If your speakers distort when you play
them loud, turn down the amplifier.

o 8. After you are satisfied with the output of
your subwoofer, you can make all your
volume settings through your main
stereo system’s volume control. The
only time you might want to re-adjust
the subwoofer’s VOLUME is when you
encounter a musical selection that has
abnormally low – or high – bass.
Troubleshooting
and Service
Gateway® speakers do not use external fuse
protection or circuit breakers because these
devices tend to impede sound quality and may
only protect the speaker to a marginal degree.
Rather, we use components and designs of the
highest caliber as an effective method of protect-
ing the speaker. However, no amount of protec-
tion will prevent damage caused by defective
associated equipment or extreme abuse.

If you have a problem, first try to determine
if it is indeed a speaker problem. Determine
whether the problem exists in both speakers.
If its does, the problem likely originates in
some other component in the system. If the
problem is in one speaker only, reverse your
speaker leads (left to right, right to left). If
the problem moves to the other channel, your
problem is not in the speakers.
