In addition to the above two links to FAQs on this forum, I also wrote a more general and extremely systematic 'tracking down ground loop problems' Q & A for SOS July 2005 that may help those with larger setups, and of course those without laptops:
Martin, I don't know whether it's just me but that article comes up all blacked out for me.
A few questions further to the above: Does one have to spec any particular kind of DI box for these duties? Or just get any bog standard cheapie one and insert it between audio output and mixer?
Also, I have problem with low level hum in my studio where I have a Flying Cow A/D converter connected to a Spirit Compact 4 mixer connected to Event TR8 monitors, ALL using balanced cables. The feed from the PC to the Flying Cow is digital, SPDIF. How can this be, if balanced cabling is supposed to solve such problems?
