Power Conditioning

[minister]

Most guitar pickup noise comes from things that balanced power will not improve (noisy, low quality light dimmers, CRT monitors, etc.).

yes...RF ... nothing you can really do about it. yet...when i had a problem, i started with a ferrite clam. then gave my stat some internal attention. additionaly, a look at the grounding and some mu metal shielding might help. things improved.

a regen system is fabulous if you can afford it.

take 480 3 phase
drive a big heavy flywheel
w/ a 120/240 generator on the other side

still ned a UPS for complete loss of power but it takes care of sags, spikes, and dirty power

Very simple -- buy an APC with plenty of power overhead. You will be very happy. I have owned many of the Furman BS conditioners which did nothing for me. I got an APC UPS and was shocked at what I was missing. Maybe the Furman helps in very isolated cases, but I had multiple furman conditioners in multiple studio locations always felt them to be useless compared to an APC UPS.

I think a lot of people who report good effects with a furman conditioner may have previously not tried the "tree limbs" method of setting up power. Methinks a power strip doing tree-limb method is nearly identical (except in special cases I didn't run into)

I'm using this APC H10... they also have an H15 with more power. Doesn't have battery backup, but when the power goes out it does so gently after about 5 sec.

Or the APC S10 and S15 with battery... pure sine wave.

Reasonable price. No Hype. Good Product.

Thanks for all of the opinions and advice. JSantiago glad that you had good experiences with the APC line because that is where I am heading. BRH those along with the J series are the ones I am currently looking at.

Thanks again.

My main room is with Dynaudio AIR, connected via AES/EBU. My little room is analogue connected (balanced off course).
In my little room I experienced some buzzes, and "flubbers". No tipical wire-buzz anyway. One of my neighbours overhere is a welding company and welding (the heavy ones) spreads EMI (we call them like that overhere) emissions over the electricity-net.
I'm not a electrician, so I looked for a proper all-in-one solution. Talking with people who have knowlidge about electricity, the word "line-conditioning" came up all the time. My sinus from the wallplug was not properly 50Hz (60Hz in US off course). It probably looked like a sawtooth or something...
Anyway, no problems with the AIR's.
So I found myself an APC:

It's giving really clean power, and the batteries come in handy. With 3500Watts I can connect the complete studio. Great!

Good luck with the quest for steady clean power!

I know you posted this almost two years ago, but if you're still on the airwaves: can you tell me if you think that the type h supply is quiet enough for use in a single room studio?

Thanks,
