John Sayers' Recording Studio Design Forum Archive

i've been lurking about for a few weeks trying to learn all i can for my own project .i'm a little confused on what excatly is balanced power.and what are the pros and cons . thanks john

Here's a couple links...

Basically put, balanced power is set up in the following config...

Normal power uses Hot, Neutral, Ground. With 120v (or 110v) on Hot.

When balanced power is used, it has 60v on hot, and has -60v on Neutral (out of phase w/ the hot side).

That's the extreme basic. Now in order to achieve this, you need toroidal transformers in line.

Here's another link: http://www.toroid.com/standard_transfor ... ormers.htm

Hope this helps.

thanks for getting back so quick.would balanced power be a protocal for a home project studio.it'll be for personal use and maybe basementband demo recording.maybe i should of been more clear on my questions.thanks ,i'm really loving this site

For a small project studio, it's not usually necessary, especially w/ the cost of them. As long as you have good grounding, you'll usually be ok. But if you have a ground issue, you may consider one. You can buy the rack mount units, but they start at over $1000.00 for most of them.

Dad, you may also want to thoroughly read the thread on star grounding in this forum; I've tried to explain the need for a common ground point with no loops, this can be done almost for FREE and makes a lot of difference... Steve

i didnt think i would need it but just want to cover all bases.the star grounding i understand,my dad was a electrican but sadly he left this world several years ago.so i have to get my info elsewhere.thanks again guys

My Dad was an electrician too; passed away in 1973, and I STILL miss him... Steve
