TROUBLE-
SHOOTING AND
SERVICE
Before returning your SW103, SW203, or
SW303 for service, you can save time (and
often embarrassment) by checking for a few
problems that are most often encountered.
Power light is not lit.
No sound.
1. Is your SW103/SW203/SW303 plugged
in to a live AC wall socket?
2. Is the power cord firmly plugged into
the subwoofer amp power input connector?
(8) on page 4.
3. Is the power switch on?
4. Has the SW103/SW203/SW303 over-
heated and shut off temporarily?
5. Is the fuse OK?
No sound from either set of
speakers.
1. Are your other components turned on?
2. Is the receiver or preamp set to the
appropriate input and is that sound source
playing?
3. Do you have an unconnected tape
monitor selected?
4. Is the SW103/SW203/SW303 correctly
connected to your receiver, preamplifier or
integrated amplifier and turned on?
Sound comes from main
speakers but not subwoofer
1. Is the SW103/SW203/SW303 turned
on (power light in the green mode) and
VOLUME control turned up?
2. Check the speaker connections for
small strands of wire touching both
terminals.
3. Some digital receivers only send a
subwoofer out signal when in the movie or
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 output to turn on. Check your
receiver’s owner’s manual for subwoofer
operation.
4. For digital receivers – make sure
the subwoofer is “ON” and the subwoofer
level is set to “0dB” or greater.
Sound comes from the
subwoofer but not your
main speakers
• confirm that the power amplifier is
turned on.
• check the RCA patch cord
• check the speaker wire connections
between the power amplifier and
main or satellite speakers.
Bass is muffled or weak
1. Check speaker wire polarity of
all connections.
2. Reposition your subwoofer. At
some points in the room, its output may
be cancelled by the geometry of the
room. Moving the SW103/SW203/SW303
can eliminate this problem.
Please refer to Item 10 in the Safety
Instructions for conditions that ALWAYS
require service by qualified personnel.
If you have tried all the above and
still cannot get the SW103, SW203, or
SW303 to operate properly, consult
