quote:

Connecting The Turntable The turntable will have a left signal wire, a right signal wire and a electrical ground wire. Connect these to your stereo or phono preamp. Connect the ground wire to the screw provided or, if no screw was provided, then loosen a chassi screw and use that. The ground wire is important in minimizing hum. I'm Hearing Alot Of Hum! This is the most common problem encountered with phono playback systems. And it can be puzzling sometimes to track down. First, you must isolate the source. Is it : * The Stereo * The Phono Preamp * The Turntable Wiring * The Phono Cartridge

Computer power supplies and earth loops are common problems.
Easy solution is buy a ground loop isolator off ebay for $25.
Iv tried many other things but depending on the situation the only answer sometimes is the isolator.

Take it it worked for you then Tommy?

Yup, only thing is you get some wierd pops come through the amp every now and then.
Its nothing because it bearly happens and if the music is up you dont even hear it.

and this isolator thing works even though the problem is at the computers end and not the mixer/amp/turntables?

Jub jub, click the link for Tommy's thread on this prob, and you'll get an idea if it is the same as yours.

The common problem is dc running from the computer end and going out through the speakers. An isolation transformer (ground loop isolator) cuts away as much dc as it can without affecting the AC.
Just look through the old thread and youll be right.

thanks heaps, which ground loop isolator brand/type did you buy and how much did it cost?
