How to wire up a Noise Filter

My experence is that most noise filtes don't work or affect equipnment sound in a bad way. Noise is a really hard thing to filter out. Save some time I would sugest finding a dealer that has several and seeing if you can demo some. Maybe find out what else is on the line.

Somewhere on the back of the Krell units near the power cord or fuse will probably be a current rating. If not, it should be in your manual. If the 2 added up exceed 5 amps then it isn't big enough. If the rating is in watts or VA then divide this number by the line voltage to get the amps.

The convention for schematics is to show inputs on the left and outputs on the right so 1-2 would be in and 3-4 out as you figured.

How do you plan to connect to this device? How do you intend to handle the ground? How do you intend to mount it to insure there is no danger.

DISCLAIMER: You are dealing voltages and currents here that could kill you or burn down your house. Unless you are positive what you are doing you should leave this to professionals. In other words, buy a commercial unit.
