Single line Isolation Transformer.

CH46E

I have a dedicated 10 awg 4 strand timex line from the fuse box to my HT setup via a hospital grade leviton outlet to a Belkin Pure AV PF60. That runs everything except my mains amp at the front of the room, the TV and the Sub Amp. I'll be adding two more outlets for those items.

My questions is: can I add one Isolation Transformer or something else where the main romex 10 awg line drops into the theater closet to isolate it from the rest of the house. I'm trying for a lower better noise floor.

My budget for this isolations transformer or other recommended item would be $300.00

Thanks.

Any recommendations? As low as the hiss maybe it drives me nuts. Also the sub amp (not on the 10 awg line or the Belkin) throws out a hum when the microwave is turned on. So I know other items are polluting the lines.

Why not just an isolation transformer between the wall and whatever components you want to run?

You know, this sort of thing.

How much capacity (VA; VA = watts if the power factor is 1) do you need?

If any of your "issues" are induced (e.g., RFI or other radiated crud from digital gizmos, etc.), I don't think an iso transformer is going to help much.

Thanks man! I'll look into that.

As far as power consumption goes..... all I know is that with everything on (except the Behriger sub amp) and running at concert level volumes my Belkin PureAV PF60 shows that I'm using about 9.5 amps. It looks like the items you set links to max out between 4 to 7 amps.

This would be a problem right? Or am I mistaken how this all works?
Thanks again!

That's a lot of juice; you'll need a big boy isolation transformer (or a couple of smaller ones)
