Hi all,

I've had an annoying hum coming from my edirol FA-101 when I hook it up 
to PA systems and have finally figured out that it occurs only when my 
laptop is plugged in and not running on batteries.  The FA-101 is also 
plugged in (boo 4-pin 1394 connections...) and then the amps I run into 
are also 3-pin plugs and leads me to believe that this is probably a 
ground loop issue.  Can anyone suggest possible solutions?  Is there a 
power bar that isolates grounds?
