Some say that when DBX is engaged, you should keep it at no more than 0db. I, on the other hand, on my 244 have on many occassions recorded into the red with no bad effects at all. I'm not sure if this advice, about not going past 0db when DBX is set is theory or what .. Personally, I found going past 0db not problematic and I certainly have not heard any compression/expansion side effects, like "pumping & breathing". If there is then I can't hear it. Btw, who came up with this "theory" ?
