Solution
• No Sound Only from Subwoofer
Troubleshooting
• Check the subwoofer's volume setting and
all connections. If your receiver has a
subwoofer on/off or variable subwoofer
output level control, ensure that the
subwoofer option it is turned on and that
the output level is at maximum.
• Make sure that the subwoofer's RCA
cable is connected to the receiver's
subwoofer output and not the subwoofer
input jack.
• Too Little Bass
• Too Much Bass
• Check: subwoofer volume / frequency /
phase control positions; receiver tone
controls; program material; ensure that
the center channel mode on the receiver
is in the NORMAL or SMALL position. If
your receiver has a variable subwoofer
output level control, ensure that the
output level is at maximum.
• Try moving the subwoofer further into a
corner or towards the wall.
• Try to separate phono cables from power
cords (they can induce hum into the
system). If that doesn't work, we
recommend you turn off your subwoofer
when it is not in use. This is most easily
accomplished connecting its power cord
to a switched power outlet on the back of
your receiver.
• Check for faulty phono connecting cable.
• Check: subwoofer volume / frequency /
phase control positions; receiver bass /
loudness controls; program material;
move subwoofer further out of corner or
away from wall.
