Re: [ARSCLIST] Grundig EQ
Plus, MRL has a very handy chart in their "choosing and using" pdf that shows how to, for example,
use a 15IPS NAB tape to align a 15IPS CCIR preamp.

On any vintage (especially naïve) tape recording, adjusting playback azimuth
is your first priority. Generally, the slower the tape speed and the more
informal the recording, the more this becomes important.
Richard Hess has some pointers on azimuth adjustment on his web site, but I
like to use a transfer function display because it shows combing in great
detail. Whatever method you use, the results can be profound.
In other words, do your playback azimuth adjustment before playback
equalization adjustment.
If your budget allows, MRL sells alignment tapes for various speeds and
standards. I think they offer NAB, IEC, CCIR, AES and Nagra alignment tapes.
You might want to call Jay McKnight - see http/www.mrltapes.com for further
advice.

I was hoping to find graphical representations of eq curves so I could compare
what I am capable of reproducing (NAB, IEC) with what the recording might have
originally been done with to see how to compensate. That will help me
determine if it is playback equalization that is causing the evident lack of
high end content or whether the recordings simply don't have any, because of
the original recorder's limitations, the mic used, or whatever. I can crank
up the high freq. shelf eq on my Studer console to emphasize what is there but
it boosts the noise as well.
