I feel that if you have a significant amount of money/time invested into your Home Theater you will want something to protect it. I purchased a Panamax Max 5300, not just for it's ability to protect my investment, but to provide additional Features such as:

DC Voltage trigger input and pass-through output for initiating a startup/shutdown sequence.

Protection for Satellite, Antenna, RJ-11/45

11 Outlets
