Ensure the power cord is connected to the subwoofer and plugged into a live AC
outlet.
Ensure the subwoofer’s volume control is NOT in the minimum counterclockwise
position.
All PSB subwoofers utilize signal sensing auto on/off circuitry. If no signal is sent to
the subwoofer, it will not power up and the front panel power indicator will not be
illuminated. When using the subwoofer output of a receiver or processor, no signal
may be immediately present in this output. The subwoofer will only power up when
bass appears at the subwoofer output.
If the low level cable or speaker cable connection is poor or has been severed, the
subwoofer will not power up. Swap cables to determine if this is the source of the
problem.
To ensure the problem is not associated with the subwoofer, rapidly disconnect and
connect the subwoofer low level or high level input. If the subwoofer power indicator
then illuminates, the receiver/processor/amp may not be sending a signal to the
subwoofer. When driving the low level inputs from a subwoofer output, ensure the
receiver/processor is correctly configured to provide signal at the subwoofer output.
Check the main fuse located in the power cord socket and replace as required. If the
new fuse also blows, the subwoofer amplifier requires service.
Sounds distorted
Lower volume if the subwoofer begins to sound distorted to determine if playback
at a lower level solves the problem. If a slight reduction in level solves the problem,
were you being realistic in your subwoofer level setting? If the distorted sound
remains at a low level, one or both of the woofers may be damaged.
Hum Hum that appears when using the subwoofer’s low level input(s) is usually caused by
using an inferior, damaged, exceptionally long low level cable or cables routed near
high current wiring/appliances. Replace/shorten the low level cable connecting the
subwoofer to the source equipment (receiver or processor). Low level cable runs of
longer than 20 feet may require the use of a line driver (not available from PSB).
Hum heard when using the subwoofer’s high level input(s) is usually caused by an
intermittent or missing positive or negative connection. Ensure there is a good
connection between all speaker wires connecting the subwoofer and receiver/amplifier.
If the subwoofer high level connection is routed through a switch box, ensure the
box shorts the positive and negative connections together when the subwoofer should
be inactive. Hum will result if the switch box floats the positive or negative connection.
Decreasing the volume control of the subwoofer and increasing the volume control
of the receiver/processor/amplifier subwoofer output can sometimes reduce hum to
an acceptable level.
