Optical out of DAT

ilaludba · 5th July 2011

I basically want to run my music through my Sony 750 DATs AD/DAconverters and record via optical out to a M-audio microtrack.
I put the DAT into record mode, play my music into its analog ins (sounds great through headphone out of DAT) but all I hear is a horrible loud fuzzy noise when I listen back on my microtrack. The optical/coaxial cables are new, I've made sure they are straight, the input of the microtrack is coaxial so I'm using a optical IN coaxial OUT converter, might this creating a problem?
I downloaded the 750 manual but it doesnt help in this area.
The sample rate is matching, (sais automatic on microtrack) and bitrate is 16bit.
Do I need to load a DAT tape to enable the digital outs? or is there some copyright restriction being activated? doesnt say so on the dat screen.

HELP

Hmmm, never tried this myself, but try playing a DAT with something recorded on it and see if the M-audio microtrack will pick it up. If this works, then your solution may be to record your track onto a DAT and transfer it this way.

My my Tascam DA-30 DAT machine, the only way to acitvate the inputs is to have a DAT tape in the deck, so yeah this may be your problem.

Lately I have been listening to some of my old DAT recordings, they sound phat as HELLLL!!! Thinking about testing some final mixes on my old DAT myself, even if it is at 16 bit.

You also need to check the clocking. It's not enough that the sample rates on the sending & receiving devices match, you have to make sure that one of them is the clock master and the other is the clock slave. And it's not likely that your DAT machine has an external clock input so you need to use the DAT as the clock master and set your DAW/Microtrack to be clocked from the incoming digital audio signal it is receiving from the DAT, not from it's own internal clock.

Thanks guys, tried recording digital out with DAT tape in and playing but no luck.

I dont see an option on the microtrack for slave clocking or in the manual, its a pretty basic hand held recorder, just sais spdif input!

Like most consumer DATs, the Sony 750 will only operate at 48kHz when using it's analog inputs (I used to have a similar Sony unit).

So are you sure that both of the other devices (the optical-to-s/pdif device and the M-Audio device) are set to 48kHz? Just because they say 'auto' that doesn't mean they have correctly identified the signal and set themselves to 48kHz.

What are you using for the optical to coax conversion?
