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.

Does what it's supposed to do!



Panamax M8-AV

William from Brookfield, CT on 9/3/2018

Crutchfield Customer Review (What's this?)

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.



Great Product

Dana from Kinston, NC on 7/3/2018

Crutchfield Customer Review (What's this?)

I live in an older home so I needed protection from surges from power company surges to severe thunderstorms. Also wanted a protector that helped condition the line and keep it clean so my audio enjoyment could be optimal. So far love this Panamax M8-AV.

Pros: Plenty of receptacles for my AV system. Does a great job of eliminating power line noise.

Cons: None

Crutchfield customer from Henderson, NV on 2/20/2018

Crutchfield Customer Review (What's this?)

It does what its suppose to but depending on your set up you'll have to stand it up or mount it on the wall.



Handsome and it works.

Crutchfield customer from Jacksonville, FL on 7/20/2017

Crutchfield Customer Review (What's this?)

Simply put it looks so much better then the unit it replaced. Picture on Sony seems steadier especially when AC cuts in and through some mean thunderstorms we have almost everyday here in Florida, very pleased with Panamax M8-AV.

Panamax M8-AV Works Great for Embroidery Machine

Anne from Rhinelander, WI on 8/23/2013

Crutchfield Customer Review (What's this?)

My new embroidery machine required a surge protector with a step up/step down transformer. This unit will protect against line surges and low voltage. Crutchfield Representative was very helpful, and the price was good. Many sewing/embroidery machines are now computerized and the cost can be substantial. The Panamax was the only protector that fit my needs. I also checked with APC and they do not have a unit like this available.

Pros: Protection against line surges and low voltage. Easy installation. Relatively small footprint, fits on top of my sewing table. Easy access to connections.

Cons: none

Cons: none

So far so good. I have owned several Panamax products over the years and not been disappointed. So far, this product is no exception.

Pros: Size and functionality. Appealing looks.

Cons: None.

Good item

Wally from Southampton, NJ on 8/13/2012

Everything works as advertised. It hasn't had a serious "test" yet . Thats why 4 stars.

Pros: Well made, as far as I can see.

Cons: None yet

First one defective

Susan from Taos, NM on 7/6/2012

Crutchfield Customer Review (What's this?)

Worked for a day, and then none of the unit's outlets would power anything despite the green indicator lights showing that supposedly all was fine. Must be a defective unit. I am going to try a replacement as the features on this unit are great (if it works).
