Just a general comment since I don't do allot of live tracking gigs- and it fits the same for a good live sound in general; A good clean, stable stage environment makes for a cleaner tape. Things like appropriate volumes, monitors that aren't booming or with frequencies that are
near feedback -factors that avoid adding long decay times in the room and on stage.
Ever notice how if stage monitors happen to be a major part of what's heard out front from the mains that it's often a muddy (it's mostly the nondirectional frequencies) sound bouncing in off the stage back wall/ceiling out of time? That's a cue (or opportunity

) for asking if maybe the monitors can be filtered down some to sacrifice on the low end for the sake of cleaning things up overall.
Along the same line.. (rant time

Allot of PA guys either don't seem to hear, (or don't care?) to clean up even fairly obvious low, low mid resonances in the system/room...
