I downloaded the manual a few days ago. Because TDK no longer makes this burner, I couldn't find the manual at the main TDK site; I had to go to http://legacy.tdk.com. Unfortunately, I don't remember the exact page on the site that had the manual, but it wasn't helpful, anyway. All it said was that the DED+440 has audio outputs that you can plug into stereo equipment. I also emailed TDK but they said they couldn't help me because the product has been discontinued. I hoping there was someone at this site who owns or once owned the thing and was able to solve this problem.
