Hello I have the opportunity to buy a Furman P-6900 AR E regulator (30A) from an audiophile for a very low price, which makes me consider it. www.trius-music.de/download/Furman/Datenblatt/Furman_Technote_P6900ARE_Applications.pdfI want : - electrical safety for my whole audio setup (I think 32A is required, it's up there) - a definitive way to regulate the too-high voltage I get in the studio (248V, rather high delivery for EU, it's above nominal) - and eventually maybe some improvement in S/N ratio too, and have the gear be its best self. Should I go for it ? Serious kit or snakeoil ? Anybody using such equipment to protect their gear ? I can get it for a bit less than a third of the regular unfriendly retail price (4500 € !). Cheers ! Louis

Dumb but simple questions. 1 do youhave a 30 amp feed? 2 is your voltage over or under? 2

Yup, 30A feed (but I'll have to install another wall socket, right now the schucko is specd for 16A).
Voltage going over the 240 nominal value. steady at 248V, not good for vintage gear in the long run. Some expect 220, even 210 ?

The 20 amp here has done an excellent job of smoothing out all the HVAC crap!

Just a FYI - it won't protect against a lightning strike. (Personal experience there). I haven't noticed any noise reduction. They do tend to smooth out power delivery to 117v - US here. It might offer some peace of mind. Not sure if I would buy them again. My power here is pretty stable......except for lightening.

Thx for your perspectives.
I read the thread about the Storm that hit your studio last year. I pray every night that it doesn't happen to me.
I went for it, I'm paying in 4 times, I won't feel it that much. "Peace of mind," exactly. If feels like the responsible thing to do. Buying a Dangerous comp would have been more thrilling, but it can't always be compressors.

So - what SHOULD we buy that offers some protection against brown outs?

So - what SHOULD we buy that offers some protection against brown outs? Those power regulation units generally DO work against brown outs and over voltage - just not against significant spikes. (IME) In LA - the studio regularly went from 90v to 130v in swings. Depending on the time of day and area load. The regulators smooth that out pretty well if that's your problem. Problem is that it will take a bunch of em to power a well appointed studio. And they are pricey.

So - what SHOULD we buy that offers some protection against brown outs? Your asking the billion dollar question, but first we have to ask the more basic question, how do I know I have an issue? Sure you could watch the voltage display on your typical over priced and hyped rack mount strip but your going to only be there for a limited amount of time so the sample size is way to small. Even then is that VM in your rack quik enough to show it? A quick logging Voltage meter could tell you there is a problem but only if it was plugged in when those connections exist. An example from my old road warrior days; there is a banquet hall in Racine WI that would give you sporadic spikes. These spikes only occurred if the dish washer was running and at the exact same moment the HVAC kicked in and the compressor on the walk in cooler kicked in. You fine unless all 3 presented at the exact same time! It took 4 days of experimenting and investigation to figure this out. Probably should have just rented a Showpower Kohler generator ( did I mention on the night that lead to this investigation 2 VPs from Kohler were in the audience). Now for the irony of this all, years ago Mr Furman told me “ you know if manufacturers would build gear with really good power supplies I wouldn’t have a buisness”. That’s not going to happen. I personally stick with Furman as long as the unit has SMP, so that even after it has protected me from a spike, it still keeps protecting ( kind of Duh don’t you think). Some of the very high dollar pure sine wave regeneration units probably do a decent job, but you’re talking big bucks and limited current. Some swear by Balanced Power Transformer based units, but they don’t really protect and honestly I’m not sure considering every PSU in a piece of audio equipment I have ever seen uses PSU’s designed assuming they will see single ended power.
