Very newb question here, but its driving me nuts. haha. What exactly are the rack mount converters such as the apogee 800 used for. I know it says it's to convert your analog audio to digital but what does that mean really. For example if I am using a Digi002 with protools 8 into a Apple mac, is this something that can make my sound less artificial/digital if I'm using stuff like the line 6 pod or what. lol. Sorry for the stupid question but I was hoping to learn what this can do for a studio in detail and I have done research and reading the specs and what they do on the retail sites isn't clicking with me. haha. take care friends!!!!
