Re: [ARSCLIST] Consumer open reel EQ curve?



Hi, Jeff,

What's wrong with the internal preamp on the A807? (I have my own pet
peeves, but I'm wondering why you're going the external route).

AME was never a consumer format, so I would dismiss that. I am one of a
handful of people equipped for AME reproduction on current equipment, and
I've supplied some of the AME filters to other transfer houses. You'll find
it on 2- and 3-channel masters from the 1960s at 15 in/s. See the info at
http://www.flash.net/~mrltapes

CCIR is widely used in Europe, but I doubt (m)any of your tapes will be
that format. A stock A807 can be set up to switch between CCIR and NAB.

Please note that at 3.75 in/s, there is no difference between U.S. (NAB)
and European practice. Again, see the MRL Web site. The table on page 3 of
the "Choosing and Using..." document indicates that the IEC EQ was used
only in professional circles in Europe. Consumer machines and pre-recorded
tapes worldwide apparently followed the NAB standards.

Cheers,

Richard

I'm getting a Studer A807 fitted out for archival use and plan to use an
external head preamp. I've been asked what EQ curve I'd like to use (NAB,
CCIR or AME) but am not sure what curve, if any, was used for consumer open
reel decks and/or commercially duplicated reels? Most of what I'll be
working with is 2 and 4 track reels at 7 1/2 IPS, with about a 50/50 mix of
consumer recorded and pre-recorded reels. In cases where I have recording
deck info it's generally machines such as older Teac A series, Sony and Akai
units of '60s vintage. Any help is greatly appreciated.



Thanks,




Jeff Kane
