OK
1st – You must use a tc enabled machine. NOT ABS TC. This means a higher value machine like a Sony PCM 7030 or 7040.
2 – Control the DAT deck by using a 9 pin control wire (RS232 protocol), exactly the same as if you were capturing from a Digi Beta or HD CAM SR etc etc. It will show up in the VTR preferences so you can set and select the VTR characteristics .
3) Capture the audio exactly as if it were a Video deck, just plug up the AES/EBU / or analogue outs to the capture machine and away you go.
The audio recordings will be recorded against the original DAT tc as if it were footage on a VTR.
Hope this helps
