At this moment, I'm at my office's system and don't have access to my private box, I'll check this in the evening and report. Best wishes, Oliver P.S. Just a stupid question: are the DACs of the M-Audio Revo 5.1 capable of beeing initiated by an entry level of volume (or current in this aspect)? Maybe such a default level is choosen too low?Received on Mon Feb 19 2007 - 07:44:17 UTC
