What does a voltage meter on the back side of one of these units look like, ever tried??

I just ask because my converters opened up a bit when I started using my Leibert always on UPS and Monster regulator.

Any recommendations on what does work then?? Pretty scary proposition to leave your gear hanging out on the grid for lighting and brownouts.

For line noise, I put in a Corcom filter into each piece. For transmission sags or noise, a large isolation transformer mounted external to the building will do the trick. Then you can install an audio ground rod and float the AC from the rest of the building. You could even get an electrician to install hospital grade AC jacks into the wall. While at it, use the split secondary from the iso transformer to wire the AC + - 60 volts or balanced power. An 80 to 100 amp iso transformer will run about a grand but will eliminate common AC problems.

The plus is no more current limiting. =Big bass!

Ummm....the question was re: a home studio

not a pro studio.

I don't have a grand for an iso transformer but I do have $300 for that monster thingy which made my studio much quieter

YMMV
