Guard your home theater system against harmful spikes and power fluctuations with the Panamax SP8-AV. This surge suppressor also filters out the RF (radio frequency) and electromagnetic interference that can degrade your system's performance.

The SP8-AV comes with eight outlets, each conveniently spaced to allow for bulky transformers. A set of coaxial input/output jacks protects your cable, antenna, or digital satellite TV connections. There's also a protected telephone line input/output.

Product reviews from the Crutchfield Labs

If you use power strips at home, upgrade to this one immediately

Written by Zak Billmeier, Video Producer, on 11/4/2013 1:59:00 PM

Like many people, I had a hidden mass of wires behind my entertainment center where everything plugs in — my TV, Blu-ray player, Nuforce Dia amp, and powered TV antenna were plugged into the type of power strip/surge protector you can get anywhere for 7 bucks. Not a great idea. So I upgraded to the Panamax SP8-AV, mostly for safety's sake but also to address a nagging problem in my setup.

The problem: the NuForce Dia amp was crackling whenever I switched inputs. I have re-purposed an old Airport Express to serve as an AirPlay® hub for the Dia, but I heard a loud electronic crack every time I switched to that input. The solution? The SP8-AV. No more crackling noise. Panamax outlets are protected and feature noise filtering, eliminating interference between components. And if lightning strikes, I know my TV and everything else will be safe (even guaranteed by Panamax).

Even if you're not experiencing electrical interference like I was, you owe it to your gear to keep it safe. After all you've invested in it, a little protection goes a long way. I can't believe I waited as long as I did, and now I have these deployed in other areas of my home.
