I've never been a fan of DBX NR, which is not completely transparent even when it's working, and which can have "pumping" effects even when it is. Sure, if you're using cassette or 8-track it may have some value, but I don't think it has any place on an open reel deck. If you need NR with a reel machine, there's Dolby A for that.
Akai 747 w/DBX question
Hopefully there are still some reel to reel folks out there. So I currently have the 747 w/out DBX, and I have an opportunity to pick up the DBX version from a local person who owns a rather hi end audio store here in town. My question is: Is the Dynamic range extension worth the extra coin over the non DBX version? I don't record music from CD's to tape, and the added DBX if it works well should do wonders for recording from vinyl. I have owned reel to reels all my life but never this piece. Just curious if its worth the effort, and if you think it will it be an improvement.

barnettk I was interested in the DBX mainly to get the bump on dynamic range which also by proxy reduces the noise however like I said the faster recording speed definitely improves things for sure. The Dolby A I think would improve the highs.Dolby ’A’ will improve the highs and DR. Not really a fan of demagnetization. There are two camps on that topic and it seems to be a little dangerous for me to try it myself even though I do have a demagnetislzer. Your thoughts on that.I was not aware that there are two camps of thought about demagnetization. There’s no question that tape deck parts can become magnetized with use over time, which is obviously not good for the deck or any tape played on it. Demagnetization is actually part of routine tape deck maintenance. That it can be improperly done doesn’t mean that it should be avoided, imo. |
barnettk I have a demagnetizer, and the way I did it was as follows: Start about 6 feet out and slowly work my way to the head (without touching it) then slowly work my way back away from the head.That is not the correct way to use a head de-mag, according to the instructions I’ve seen that accompany them. The de-mag should be placed close to the head - not touching, as you state - and then energized. After rotating it closely around the head (or tape guide), the de-mag should then be gradually drawn away from the head, and then switched off. |
barnettk ... this device is called "Han-D-Mag"That is the gold standard in head de-mags and is still being manufactured by R. B. Hannis. |
