I keep getting buzz/noise when I'm recording vox with the Voicelive 2. My chain is Fet 47 > TC Helicon > Duet > Computer.

I've played around with Line vs Mic IOs but the same noise is there regardless of the settings. Could this be a power supply issue? I don't fully understand this but have read some other articles that are sorta similar. Any help would be greatly appreciated. I just want a clean vocal recording with the TC Helicon dry fx.


  • Laptop or desktop, grounded or ungrounded power supply?

  • Desktop. The helicon has a two prong outlet connection. It is plugged into the same powerstrip as the computer.

  • OK, you may have to investigate grounding wiring, straps between devices' cases. I've never worked with un-eartherd mains, it's illegal where I live.
