Weren't we all dealing with this in the Quad and 1" days? I mean, it
didn't really matter which you used, 100 or 75, so long as you tweaked
the TBC to the reference. I just remember you needed to use a little
experience to set up analogue 100% as the tape really couldn't handle it
Vince, what are you recording on? I mean D1 is D1, and if you are using
D2, its a bit like driving an old 1".
