Problem
Cause
Solution
No output from the
subwoofer (LED
lights up red).
No output from the
subwoofer (LED
turns green).
Little or no sound
from one main
speaker.
Bass output from
subwoofer is low.
S u b w o o f e r
thumps when the
system is being
turned on and off.
The subwoofer is not receiving a
signal.
Subwoofer amplifier is faulty.
Connection between subwoofer
amplifier and woofer is faulty.
Driver or amplifier is faulty.
You used speaker level connections
and have mixed up the polarity of
the wires, thus shorting one channel
of the main amplifier.
You used speaker level connections
and one or both your main amplifier’s
‘ - ’ are not true ground.
Level on subwoofer or receiver’s
subwoofer output is too low.
Noise is being generated by up-
stream equipment.
• Recheck the connections between the source and the subwoofer. If you
are using a receiver with Dolby Digital, make sure you are connecting
to the subwoofer pre-out and not the subwoofer input on the receiver.
If you are using the wireless connection, make sure the transmitter is
powered (l.e.d. lights up), and the ‘Wireless/Wired’ switch is set to
‘Wireless’. Make sure the channel selection are the same on the trans-
mitter and receiver. Check and see if the led above the ‘Wireless/Wired’
switch is lit up solid green. If not, move the antenna, transmitter, and
subwoofer to get better reception. If you are using the wired con-
nection, make sure the 'Wired/Wireless' switch is set to 'Wired'.
• With the volume on the subwoofer turned to a low setting, try
plugging the subwoofer directly into a DVD player's analog output,
ipod, or other MP3 player or lightly touching the unplugged end of
the input cable. If you hear noise from the subwoofer, the problem is
with your connection to the system. If you hear no noise, try turning
the volume on the subwoofer up some more. If you still hear no
noise, call/e-mail technical support for authorization to send the
amplifier back for service.

• Correct the polarity of the speaker wires by matching the +/- from
the receiver/amplifier to the +/- of the subwoofer’s speaker level input.
• Connect only to the channel that has a true ground ‘ - ’. If neither
channel has a true ground ‘ - ’, e-mail/call technical support.
• Increase the volume of the subwoofer and the subwoofer level or
LFE level on the receiver or other source. It is best to set the level
of the subwoofer relative to the other speakers using a test disk and
a Radio Shack SPL meter, or built-in tones on your pre-amp/pro-
cessor. See “Volume Level” in Step 4.
• When you shut down your equipment, turn off the subwoofer first.
When powering up, turn on the subwoofer last.
