Possible Cause #2
PowerCenter is plugged into a switched outlet on a component which is not turned on. The PowerCenter will not receive
power and therefore will not provide power to the components plugged into the PowerCenter's outlets.
Possible Solution
• Turn on the component.
NOTE: For the best possible performance, plug the PowerCenter into a wall outlet, not an outlet on
another component.
Possible Cause #3
The PowerCenter is defective.
Possible Solution
• Please see page 31 for warranty information.
PROBLEM – Speakers emit a humming or buzzing noise.
Possible Cause
The PowerCenter is sharing AC power with equipment that is not properly grounded.
Possible Solution
• Connect your PowerCenter to a dedicated outlet.
