I was asked to turn a DASH tape into files. The tape owner was fairly
certain it was made on a SONY machine.
It would not play on my 3402 which still plays other tapes.
I baked the tape prior to playback which has been necessary for at least
a few years and is being done in Hollywood on multi-track DASH.
I believe the tape is tails out, but I could not hear anything on the
aux tracks. When played backwards, I can hear backwards organ sounds (it
is a theatre pipe organ recording) on one channel only.
It appears to be about 15 in/s.
I have posted on my website after much research that there are five
variations of the Mitsubishi Pro-Digi format.
1. The original X-80 machine had a 50 kHz sample rate. It’s tapes will
play back properly on a 50 ks/s X-80, or 4% slow on a 48 ks/s X-80 or an
2. Later X-80 machines had a 48 kHz sample rate. It’s tapes will play
back properly on a 48 ks/s X-80 or an X-86C. Presumably they will also
play 4% fast on an original, 50 kHz X-80.
3. The switchable 44.1/48 ks/s X-86 tapes will play on an X-86, X-86C,
4. The high-resolution (88.2/96 ks/s) X-86HS tapes will only play on
5. The “radio-station” 7.5 in/s tapes made on the X-86LT will only play
on that machine.
As far as I know there is only one Sony format.
So what do you think this tape might be?
