I know what you are probably thinking, but its probably not what you think it is. I have a Digi 002r and a Presonus Digimax FS. I connect them via Lightpipe. For some weird reason I get occasional clicks and pops. Now the biggest problem with that, is that I get it on my channels 1-4. (Digi002r). Thing is, I only get the clicks and pops ONLY when the Digimax FS is connected. (all the digimax channels are fine and don't pop). When the digimax is disconnected, and I just use the 4 channels on the 002, I get no pops and clicks. Does anyone have any thoughts or ideas of what could be a possible fix? I know its a problem with the digimax, because I tried mine and my friends. I got the same results. Thank you.
