The pres in the Control24 were based on the original Focusrite Green Range, but really sound more like the Platinum Range (aka an Octopre). Early on there were some issues with the Power Supplies, but Digidesign quickly resolved that issue. I remember a client of mine had a new Control24 go down just a week after buying it---Digi sent a new unit all the way across the country OVERNIGHT Saturday delivery to take care of him! This was several years ago, I've seen very little problems since then. I have (2) Control24's (one of which I'm selling) which are totally fine. I had a third one awhile back that I sold which has also been fine. Back to the pres....that's not the reason users buy this product. If you need them, they are there---but they are really a plus rather than a feature, IMHO. I use the Control24 extensively and plan on moving up to a C24 (which is why I'm selling mine)..... I get quite involved when I mix, turning knobs, pressing buttons, zooming in, toggling, assigning parameters all on the fly...You just can't do this on any other control surface unless you get a C24 or higher from Digidesign. I have (2) cables connected into my Control24... the power cable and the ethernet cable. I don't dare use the monitor section in there, I have a Central Station for that!
