So I bought a Digidesign 192 and this card had some issues. Channel 6 had a 120 Hz hum and Channels 1 and 2 were a bit noisy. So I got a new card and I figured I just put it in the 2nd slot instead of the digital card and use the still functioning channels. Well for some reason the 192 then didn't show up in Protools. I have no idea why. But it does seem to work in a 192 in 1st slot. So I'm selling it for parts, not working. Please don't order this with any expectations. I'm just giving you some background that will help you decide whether you have the expertise to fix this unit and make no claims that it will work at all. So bid based on that information.
