How accurate is the metering in Butt - running a Rodeprocaster II pro into butt - but the meters do not always match at all - the procaster meter say the mics are real low but butt put them in the red . Some of the audo track are in the red on rode but no not in butt What should we be mixing to in Butt -6 or is 0 the 0 as per a normal VU meter ?
