If you think something so useful to be learned, then post each numeric specification that says so. Not difficult. Where are the only facts that are relevant? Written specs with numbers. Not hearsay speech. Why do you never provide what is only relevant?
Painful is to read flowery paragraphs that recite myths and never once say why. Where are numeric specification for the Surgex? Oh. You cannot provide them because you do not understand the question? It not bad English. Its bad comprehension of simple questions. Where are those specs?
Professional studios use Surgex, Brickwall and Zerosurge for what they do best. Series mode filters perform noise reduction. No informed engineer installs them for surge protection especially when a wire inside each bypasses that filter. Compromises any assumed' protection.
Embarrassing is anyone who would recommend a Furman product for surge protection. Obviously. Just view the spec numbers and its price. The word scam applies to too many Furman products.
Surge protection means that energy is never inside the building. No way around reality. Learn, for example, what van der Laan and van Deursen did to fix a nuclear hardened maritime communication center that suffered repeated surge damage. They did not waste money on Surgex. Instead they modified a defect that caused lightning damage - earth ground.
Or a case study for a Nebraska radio station that suffered repeated surge damage. Damage made easier because untrained broadcast engineers (apparently only technicians) disconnected grounds - made things worse. Again, no money wasted on Surgex or other plug-in protectors. Every solution simply fixed the only thing that does surge protection - earthing:http://www.copper.org/applications/e.../nebraska.html
How does a Surgex stop what three miles of sky could not? How does its what - 2000 joules - make hundreds of thousands of joules magically disappear? I keep asking those engineering questions. You avoid them by posting meandering and flowery English. And pretend you do not understand simple English.
Why do professionals not use Surgex for surge protection? Why do professionals always want surge energy outside a building? Because a superior solution that means direct lightning strikes without damage also costs tens and 100 times less money. A protector is only as effective as its earth ground.
Only repeating reality because it is reality. And because you always avoid those same damning questions. Series mode filters do not magically stop surges.
