• Make sure the PowerCenter’s AC power plug
is plugged into a properly grounded 120

• A wall switch may need to be turned on. Try
turning on the light switches located near

Speakers emit a humming
or buzzing noise.
The PowerCenter is sharing AC power with
equipment that is not properly grounded.
• Connect your PowerCenter
to a dedicated outlet.
• Try unplugging different components from

to be improperly grounded, attach a copper
wire from the component’s chassis to the
PowerCenter’s grounding post.
