As a general note, we want to remind you that all electrical equipment must deal with poor power conditions and power outages. Hardware and software designs can be sophisticated in this regard and we put enormous effort in this area. | As a general note, we want to remind you that all electrical equipment must deal with poor power conditions and power outages.

"Surge" means a lot of voltage coming through the power over a short period of time. That's pretty rare and the main cause is lightning, some accidents involving power lines (mostly on poles) being cut and touching something they shouldn't (e.g. the wrong side of a power transformer) and some really big compressors (e.g. industrial-sides freezers or fridges) turning on or off. | "Surge" means a lot of voltage coming through the power over a short period of time.

With the exception of lightning and some very bad power accidents, the Power Stand can handle that all fine by itself. With lightning, anything is possible. No piece of equipment that I know will survive a direct hit into a directly connected power line. But then again lightning might strike a few blocks (and transformers) away in which case a surge protector might be able to take the first hit and die quickly enough to protect the attached equipment. | With the exception of lightning and some very bad power accidents, the Power Stand can handle that all fine by itself.

In this regard even cheap surge protectors will work fairly well and there is only a really small number of cases where a cheap and very expensive surge protector might make a difference. | In this regard, even cheap surge protectors will work fairly well and there is only a really small number of cases where a cheap and very expensive surge protector might make a difference. | ||
On a side note, its a good idea to have all equipment that connects to the Power Stand on the same power strip. That helps with ground loops. On the other hand it's not a good idea to turn things on and off with the switch on the power strip. That may cause your fuse to blow (due to the so-called "in-rush current") and might result in pops and clicks. | On a side note, its a good idea to have all equipment that connects to the Power Stand on the same power strip.

Our system (and many others too) are designed to deal with all sorts of AC power fluctuation and have high-quality internal regulators. These regulate with much higher precision than any external device could do anyway, so "conditioning" or "cleaning" up the AC power doesn't make any audible difference whatsoever. | ||
