[QUOTE="andrew gissing, post: 4291, member: 75"] Hi, Reading the pro-2 manual I came across this: ...the remote stage box contains a 12dB/Octave 30Hz filter. It is recommended that this is used at all times for optimum A/D performance. However it may be bypassed.... (page 70 op manual). I'm puzzled by low frequencies causing an issue in an AD converter. I understand aliasing and nyquist but that's at the high end. And I do employ high pass filters to clean up my mix... but the comment in the manual is directed at AD converter performance. This I don't understand. Can anyone comment on this ? Andrew [/QUOTE]
