Re: [ARSCLIST] NAB vs. DIN recordings
Butterfly heads were a pain in the patootie for yours truly because I'd bring
in tapes I'd recorded on "normal" 2-track heads and find we'd be broadcasting
erase pulse or other center channel information. All the CBC's Studers had them
in Toronto and Edmonton.

Hello,
I would like to query the collective wisdom of this list for
facts/studies/specific anecdotes as to the pervasiveness of DIN
(100-mil) 2-track 1/4-inch heads on used Studer tape machines. I have
found them on machines both from the CBC and on machines believed to
have spent most of their life in Southern California. While it is more
prevalent on Studer A807s, there is no shortage of DIN heads for A810s
as well.
Of course, in common Studer parlance, the DIN heads were generally
referred to as "Butterfly" heads, but that is risky as the angled pole
pieces have been used for NAB implementations by other manufacturers,
and other manufacturers' DIN heads have parallel pole pieces.
We have four possible combinations of track width and EQ if we stick
with standards:
NAB Head, NAB Eq (assumed to be standard)
NAB Head, IEC Eq
DIN Head, IEC Eq (assumed to be standard)
DIN Head, NAB Eq
I'd like to know about the applications of DIN heads and IEC Eq in North
America. I would also be interested in the common speeds used for each
of the four combinations that you are aware of. Of course for 30 in/s
the IEC/NAB Eq question goes away and we have the AES Eq for all modern
work.
It is becoming a bigger question than I thought and I'm trying to
understand the spread and the implications.
Cheers,
Richard
