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 
X-86C.

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, 
and X-86HS.

4. The high-resolution (88.2/96 ks/s) X-86HS tapes will only play on 
that machine.

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?

Thanks!

Cheers,

Richard
