Re: [ARSCLIST] Old reel to reel 'echo' problem - thank you
Thanks all for the input on the print through issue - we obviously won't
be able to do much with it inhouse (I read one thing that said if you

extra $$$ required to MAYBE make it better - but thanks for all the help
- now I at least know what is going on!!!

Sometimes this can be cured by winding the tape through and letting
it sit for a few days.
There is a process--available only on the Studer A820 with
late-version software--called "skimming" which puts a small erase
current onto the tape in an attempt to erase only the easily modified
magnetic domains (which are the ones that are modified to cause the
I have yet to hear of any real successes in trying this though it has
been discussed on various lists. I have not tried it.
Careful application of dynamics processing (compression and gating)
in a DAW, plus sometimes editing at the beginning/end of a recording)
can reduce the annoyance factor, or if done too much increase the
annoyance factor. Never a nice thing. It was known from the beginning
and is worse on speech which is why most of the dialogue recordings
for films done on a reel-to-reel Nagra were done on special "low
print" tapes. These weren't as "hot" for music, but did better for
