yeah, i realize that the best way to do it would be with the ccir alignment tape, but was hoping there would be a way to "fake it" with an NAB tape just to get an idea of what it sounds like.... in the recording studio handbook by john woram there is a little graph that shows the emphasis differences, but i'm having kind of a hard time interpreting it... i do rememebr reading something a while back (i think by jack endino) talking about how with some machines, the values had to be changed on each card for the hf gain!! thats more trouble than i want to go through... i'll check out the mrl site though.
