The Dragon only uses the right stereo channel for azimuth alignment so it shouldnt make any difference. Of course, after ingest one channel would need to be reversed. The weakness of the Dragon would be in a recording where the right channel is very poor in the highs but the left OK. Swapping head connections wouldnt work as the special repro head is only designed to sense azimuth angle on the right track/pole piece. I guess azimuth would need to be adjusted manually.

It adjusts over a more limited range than the wide ranging field (especially oral history) cassettes that I've had to digitize, so it is not a cure-all. I have Nakamichi MR-1s as well. Yes, azimuth drifts along the length of the tape and I often monitor it with Stereotool.com 's display, one for each cassette. I'ave modified my Dragons to be remotely manually adjustable, using an "up/down" spring-loaded toggle switch. NAAC generally does NOT readjust in the middle of a tape in my experience--although I may have caught it doing it once or twice, it doesn't seem to do it when I'd want it. Here is the explainer on how the Dragon's NAAC works (and other things about this interesting machine). https://www.dropbox.com/s/ca8ksp4q6gga35k/Nak_dragon_folder.pdf?dl=0 Cheers, Richard On 2019-07-25 12:42 p.m., Martin Fisher wrote: > I haven't done exhaustive research into Nakamichi decks but if anyone can either point me to something that describes how the azimuth correction works on these decks (not azimuth theory but how the decks actually do the correction) I would be most grateful. I'm very wary of equipment that supposes it can do a better job than a discerning ear and even a modicum of common sense along with (and this is most important) caring enough to do it right. -- Richard L.
