Ensure the main power switch is on. This switch is located at the back of
the subwoofer.
Ensure the power cord is connected to the subwoofer and plugged into a
live AC outlet.
The PULSE SUB utilizes signal sensing auto on/off circuitry. If no signal
is sent to the subwoofer, it will not power up. 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 signal appears at
the subwoofer input.
If the wireless connection or low level cable is poor or has been severed,
the subwoofer may not make a sound.
Change the Power Mode switch to Off, then to ON. (Return to AUTO after
the test if you wish to return to standby).
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, then the subwoofer level was too high. If the distorted
sound remains at a low level, driver(s) may be damaged.
Hum that appears when using the PULSE SUB’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 Bluesound).
