DAT to computer via 788T
« on: January 26, 2015, 04:07:30 PM »
After fifteen years of taping retirement I am digging through my old equipment and getting ready to start taping again.

I found some DATs that I never transferred from 2001. I played them back and they sound really nice. I have no way to get the shows into my computer. I used to add track numbering on the DAT and go straight to a Fostex CR200 .

I am trying to figure out the best way to get the shows on the 788T without any resampling or analog involved. I am guessing it should be pretty easy but my inexperience with the SD and all those menus has me confused as hell.

Can I go XLR (aes/ebu) digital out to one of the XLR inputs on the 788 set to DIG on the main channel screen (the one you get when you push the little toggle left or right). Does it automatically pick up the two track stereo?

Between being out of the game for so long and  having a new machine I am completely confused.

Any help greatly appreciated.

Don't know much about the 788T, but I'd at least check that those old DAT tapes hadn't been recorded with pre-emphasis. (If so, that wouldn't have been an issue with your previous transfers to the CR200 CD recorder as CD players are designed to recognize pre-emphasis flags and automatically apply the appropriate de-emphasis on playback.) Any recordings with unremoved emphasis, though, will sound unpleasant due to that unnatural HF boost:  -> 1.3dB at 2kHz -> 7.6dB at 10kHz -> 9.5dB at 20kHz.

Here is a simple SOX command that will remove Emphasis and leave the resulting file at 48k... 

Thanks to Jason Sobel for this!

Very interesting...so that command applies an accurate digital equalization to de-skew a recording with unwanted emphasis? That is, it not merely removes the emphasis codes?

I wish I had that years ago when a friend with his new Sony PCM601 obligingly offered to do digital transfers to PC of a stack of my Sony PCM501 / VHS recordings (emphasis always on).  This resulted, as you'd guess, in bunch of emphasized wave files in my DAW...and to avoid any possible misunderstanding in downstream distribution chains (coding info getting misplaced etc.), I played safe by redoing the transfer to PC via DA / AD.

But it's pretty unlikely that the OP will be confronted with emphasis - and apologies for dragging this thread OT  - as it was mainly an 80's thing, especially with  pcm / video recorders. Plenty of things to bite your bum in those days of early digital and DAT. SCMS anyone?  :-)

I still see Emphasis in my work - transferring PH DATs to PC...  The command line I posted above was a cut-n-paste I used last month...

Panasonic, Casio, Teac, Tascam...didnt all those decks have pre-emphasis?...some not switchable.

Behringers Ultramatch 24/96 is an AES/Toslink/Spdif format converter that can toggle pre-emphasis.

I'm not a Sound Devices user and am unfamiliar with the 788, but it seems awfully unlikely that an XLR mic input would serve double duty as digital input. There must be other digital I/O on the unit.

What does the manual say?
DPA4061 HEB -> R-09 / AT943 -> CA-UGLY -> R-09
AKG CK63 -> nBob actives -> Baby NBox -> R-09/DR2d
AKG CK63 -> AKG C460B -> Zoom F8/DR-680MKII
Line Audio CM4/Superlux S502/Samson C02/iSK Little Gem/Sennheiser E609/Shure SM57 -> Zoom F8/DR-680MKII (multitracked band recordings)

Not a 788t user here, but the manual (page 31) states that it accepts digital signals via the DE-15 connector on the back of the unit with this cable. There might be other breakout cables available.

That's the nugget of information I was looking for. There is a dig selection on the mic input, but it is apparently for digital microphones that do the a/d in the mic before sending the signal to the recorder. I have been out of this game for far too long. Didn't even know they had such things.

Thanks for the help,

Hi

If I can help,

I have a TCD-D8 Sony DAT and a SD-722.

I have ordered a Core-Sound digital cable (Cheaper price, but Great !)
and I have transfered all my DAT tapes very easily...
