DAT vs JB3 question

I would be interested to hear comments from folks about this.

Would there be a difference ? To me the eventual wav from both sources should be the same, before any post processing ...

I don't know what a CO2 is but am guessing that this is a gizmo to take a digital feed from the SBM-1 and convert it to optical so the JB3 can recieve the digital feed.  Based on that assumtion: Two people each taking a digital feed from a SBM-1 - one records on a D8 and the other on a JB3.  There is abolutely no difference between the two sources - the D8 and the JB3 at this point are just transfering the bits to their particular recording medium (tape in the case of the D8, HD in the case of the JB3).  For this person to think one could have richer bass or sounder clearer is nonsense and shows they aren't very clear on the concept.  I suppose the transfer methods of each could yield different results but if each person transfered the source digitally and no processing such as EQ, normalizing or similar editing occurred then the resultant transfered sources should be the same as well (other then any differences in in tracking/indexing).

As for who should get credit on the text file...you two can scap it out over that one - seems a bit trivial to me.  If I were the patcher and doing the text file, I'd at least make a note thanking you for the patch and/or explaining that I patched out of your rig.  Ultimately the idea is that folks can track down the source person/people if there is a problem discovered, questions etc.  I also think it is always couteous to give credit where it is due.

FWIW, I've posted debunking TOD²OW!'s rampant misconceptions and half-truths.

And DGale - yes, the CO2 is a digital format converter.

There are anecdotal reports of the CO2 producing artifacts - dropped or misplaced samples - with certain gear combinations and powering options.  At any rate, simple digital format converters don't resample, though they have the potential to introduce artifacts.

Thanks folks. I wasn't sure if the CO2 resampled or did something funky...

Brian, thanks for the detailed response ...

+T's to all ...

I know the whole giving credit to who did what is somewhat trivial, but once I read TOD²OW!'s intial comments I was somewhat annoyed. It is stuff like this that makes me think twice about giving out patches. I don't want to be a d*ck, but I know when I used to patch I gave full credit to the taper ...

I think it's more than just anecdotal. Jamie Lutch tested the JB3 for but accuracy for many months and could never get the unit to be bit accurate when using a CO2. Once people started using the HOSA boxes the JB3 was suddenly bit perfect.

I do know from my own personal expereince that the CO2 is NOT perfect.  I used one for about 3 hours to take a DVD (48k) > CO2 > JB3 (48k).  I ended up with many drop-outs of varying lengths (up to several seconds) and severla bits of digi-noise.

I got a Hosa soon afterwards and never had an audible problem, though I have NOT tested it for bit-accuracy.

Also, I bought a RadioShack DFC ($10) and it is NOT bit-perfect.  I notice the same drop-outs, etc., but since it goes from the TV to the stereo and isn't really for taping...  Just for running audio out to the stereo for movie watching...
