I’ve done some troubleshooting and I’ve discovered that my L and R outputs are causing a horrible hum in studio.

When trying to record into Pro Tools, I un-plugged the cables from the L/R outputs and put one of them into the Phones input and wa la.....no buzz, hum or anything besides my music.

Are there any videos on youtube showing people sfixing this problem? I’ve spent $150 already on equipment thats suppose to take care of this searing white noise. I thought it was from this ground looping issue but its the Motif.

Any help would be greatly appreciated. Thanks!

Re: How do I fix my bad outputs on the Classic?

Mate, are you connecting to a laptop via a USB connection?

There were issues with laptop power supplies causing horrendous noise. Temporary noise free fix is to run on batteries - not possible for long though!!

More info may lead to an effective solution less radical than Motif surgery /forums/images/icons/smile.gif alt=

Oh....actually its a PC plugged into the wall. I’m going to try another PC to test everything on. Thanks.

Re: How do I fix my bad outputs on the Classic?

I’m experiencing the problem with the USB hum while connected to my laptop.  Are there really no fixes for this, other than using battery power?

Re: How do I fix my bad outputs on the Classic?

I’ve got a classic and was getting a hum on the outs until I ran the outputs into an Ebtech hum eliminator box. Solved the problem for me.

This type of issue is usually attributed to AC/ground issues. You may have something else going on, but thought I’d add my 2 cents.

Re: How do I fix my bad outputs on the Classic?

Really? I’ve noticed I get this buzzing noise in the back even when my Motif is off but I’ll try that “direct box” thing. I was seriously thinking about buying a new laptop just to end that humming/buzzing noise.
