Our take on the Panamax SP8-AV

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.

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.

The surge suppressor reacts in less than a nanosecond during a spike, breaking the connection to keep your equipment safe. The 6-ft. power cord's right-angle plug hugs the wall, for an easy fit behind a chair or sofa.

If you care about your equipment, this is a sound investment. The warranty that protects your investment in the event of failure is worth it alone, nevermind the clean power it will send to your setup. No brainer.

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

Written by Zak Billmeier, Staff Writer - Creative, 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.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

When I called to if tech support could help with a hum on my old Bose Companion 3, the tech suggested a surge suppressor with a line level conditioner when I plugged the unit directly in to the wall and the hum was louder. I checked your site and found this one as reasonably priced, and also learned that the warranty is only in effect when purchased from a certified retailer. It was a no-brainer for me. I hope it gets rid of the hum!!!! [ Mare  May 23, 2017 ]
For surge protection for a sound system [ Thomas  May 03, 2017 ]

Goof reviews online for this brand. [ Don  Sep 15, 2016 ]
This was sold as part of a bundle offered for sale when buying a new receiver. I did not need/want the third part of your bundle the Logitech universal remote but I DID NEED the first two - HDMI Cables and Surge Protector - so I liked the surge protector because it's got not only 8 protected 110 volt outlets but protected phone line and coaxial TV lines, plus filtering of RF Noise not to mention 45 + 5 STAR reviews!! Also lifetime warranty (plus $50K insurance also lifetime) sounds well made! [ Don  Sep 06, 2016 ]
