Paul Neyrinck discusses layback of a Doby E Stream to VTR
When laying back a Dolby E stream to a VTR from Pro Tools or a video editing system, it is very important to set up the VTR correctly.The Dolby E stream must be recorded to tape with absolutely no changes to the data whatsoever. That means that no input level gain controls can be active and no sample rate conversion can be active.
Some VTR’s have a setting called “data mode.” for this. Some VTR’s have a way to disable input gain control by pushing or pulling the level control knobs into a locked 0 dB position.The VTR user guide should have information about these functions. Here is a PDF of a section of the user guide for the Sony HDW-M2000:
