Hi Steve, Steve Harris hat gesagt: // Steve Harris wrote: projector from Seems I'm bitten really really hard by this ground loop problem, so hard that I a) am desperate and b) might need to return the box and shell out 100 EUR more for a Quattro. But I'm not sure, if I get the ground loop again... So I'd like to try a direct input box at first. Can you recommend a device? Normally I only connect to my hifi amp, so cinch-cinch connections would be fine. I did a bit of googling and found, that passive DI boxes are the way to go in my situation. Or the Monacor FGA-40, which is simply a cinch-cinch cable with a heavy ground filter in the middle and is around 20 EUR. OTOH, this one: http://www.interspaceind.co.uk/pcaudiobb.php, is way too expensive... -- Frank Barknecht _ ______footils.org__
