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?
