Some of you making beta tapes recently complained about the recording sound quality of the beta deck in the Capstone suite. This past Friday I had the time to check it out and I think I fixed the problem. It seems the Dolby Noise Reduction was turned off on that deck, which is why it would flash NR OFF! when you first turned it on.
This meant that a tape recorded on that deck was recorded without Dolby Noise Reduction. It would play back fine on that deck, but when played on another beta deck (almost all of which have Dolby Noise Reduction ON as a preset), the audio would sound muddy and weirdly compressed. Vocals tracks would shift in volume and the backing tracks might phase back and forth in stereo. Basically, your tape would sound like crap.
This was not some front of unit switch issue - the Dolby On/Off is buried deep within the deck, requiring Art and I to take the thing apart and flick a DIP switch on a card. It's likely it had been set this way for years.
What have we learned? First, when making any copy of your projects (analog or digital) take the time to review the content. If it's a screening copy for a festival, you should watch the entire thing very carefully. You don't want surprises the day of show, which unfortunately happened with projects recorded on this deck. Give yourself plently of time to make dubs - don't do it at the last moment when you can't respond to problems.
Second, analog copies require extra care and concern. Unlike digital copies, analog copies require that you set the input volume carefully. And since settings can vary from machine to mahine, check you tapes on other machines. If something sounds/looks weird and you don't know how to fix it, consider getting your analog dubs done at a professional house like Digitec or Horizon Duplication. Again, give yourself enough time to make this decision.
Third, if I'd had better information about this problem earlier, I could have fixed it earlier. As usual, not one Incident Report was sent to me, probably because people didn't even understand there was a problem. You should be able to hear if your own project sounds right and if not, what sounds wrong with it.
