Power protection for all your gear

The M8-AV features eight fully protected AC outlets, conveniently spaced to allow for bulky transformers. You get two sets of protected coaxial input/output jacks for cable, antenna, or digital satellite TV connections. The M8-AV also has one set of in/out jacks to protect your telephone connections.

Quick response prevents damage

The M8-AV reacts to a voltage spike in less than a nanosecond, breaking the connection to protect your equipment. The 8-ft. power cord has a right-angle plug that hugs the wall, for an easy fit behind a chair or sofa. You can also mount this conditioner on your wall for out-of-the-way placement.

  • UL 1449 Rating: 500V

  • Our 60-day money-back guarantee
  • lifetime $5,000,000 connected equipment warranty (covers equipment damaged by an AC or signal line surge while connected to properly installed Panamax surge protector); valid only in the United States and Canada

What's in the Box:

  • Surge protector with attached 8' power cord (terminated by 3-prong AC plug)
  • 41" Coax (RG-59) cable (terminated by screw-on F-type connectors)
  • 3 Mounting screws
  • 3 Drywall anchors
  • 3 Spacer eyelets
  • Installation Instructions (Eng/Fre/Spa)

A comprehensive surge protector. If you use the antenna cable surge protection, I'd use decent quality cables, especially if you have 4K coming in on the cable, as Panamax says there is a little bit of loss in the signal using the antenna surge protector.

Thanks for your question. For more info on comparing two or more models, you would be better served reaching out to an Advisor directly by phone (1-800-324-9695) or online chat. They can go over the differences in more detail to help you make the best choice for your system and your budget. [ Larry  Feb 14, 2017 ]  Staff
As far as I know and can tell no surge protector will effect your 4k capabilities since all 4k devices have the 4k capable items built into the device it self. In fact with my own research it seems a surge protector with a filter will more than likely make your 4k tv look even better. I have no idea why Crutchfield wouldn't have answered this question for you as it seems pretty simple but by not doing so you either might not order one from a them or even worse might not order this I and a 4k tv. [ Chris  Jul 06, 2017 ]
I do not know what is meant compliant....I just ordered by the product description. So far, so good - although I do not believe we have had an surge through the line. [ SHARON  Jun 06, 2016 ]
I have no idea [ ernest  Jun 06, 2016 ]
