Power Surge Damage

Lightening can even jump across open circuit breakers, so always unplug. It's the best insurance, in fact, except for isolation transformers with derived grounds, it's the ONLY insurance.

The Audience aR1p is a surge protector. Read whats on the website. "The aR1p Adept Response provides surge suppression up to 20,000 amps. Whereas surge suppression devices like the ubiquitous MOV (Metal Oxide Varistor) are sacrificial devices and wear out over time, the aR1p surge suppression does not deteriorate. We have also found that MOV devices introduce grudge to audio and video signal. The surge suppression in the aR1p is entirely silent."

Unplug,unplug,unplug please unplug.I learned this the hard way!!

Back when I repaired high-end audio for a living, a single lightning storm would easily pay my mortgage and car payments for a month . . . here are a few not-so-obvious observations from those years:

- Lightning damage doesn't always show up immediatlely after a storm . . . its common for semiconductor junctions to become damaged, and then outright fail after a little bit more use. CMOS components seem to exhibit this behavior the most.

- A unit's suceptibility to lightning damage is heavily influenced by lots of extremely subtle aspects of its design, especially its internal routing and size of ground traces and connections. Well-designed stuff simply breaks less, including from lightning.

- It's actually possible for equipment to be damaged by lightning even without being plugged into power, or having any connections made to it whatsoever. I personally had the electronics in an unplugged MIG-welder destroyed in this fashion - a cloud-to-cloud strike directly above my house induced a current in its large transformer core purely from the EMP field. So there are of course many situations where even a theoretically perfect surge suppressor will do absolutely no good.

In my opinion, the two best defences against lightning damage are:

- Making sure the household wiring is in good shape, and everything is up to modern standards and codes. Not necessarily in an audiophile-overkill sense, but if you have an older home with questionable workmanship in wiring from many revisions, or your system includes multiple wall outlets, multiple circuits, extension cords, and/or cheater plugs . . . or your home's electrical panel is stuffed full of doubled-up breakers and has poor grounding . . . chances are that you're more suceptible than average.

- Get a good homeowner's or renter's insurance policy, with generous replacement-value lightning-damage coverage on your electronics. Because in the end, when mankind goes up against Nature . . . we're bound to lose eventually.
