I reviewed a Marantz cassette deck last year, looking for
something I could recommend to the home-archivists who want to
digitize the closet full of cassettes of their band's shows from
30 years ago, but who no longer have a means to play them and
wouldn't spend the bucks on a restored Dragon. It has a Noise
Reduction switch (for playback only), but no B/C switch. I asked
their tech support about it, assuming that it was Dolby B, and the
answer was that it works for either B or C.
<br>
<br>
I didn't have a good way of testing how good of a job it did on
either - the best I could do was to compare playback in the
Marantz with that of my TASCAM 112Mk2, but with several other
significant differences between playback on the two decks, I
couldn't really evaluate the NR decoding.
<br>
<br>
It turns out that what's in the Marantz (and also in an almost
identical deck from TASCAM) is that it's not really Dolby, because
there are no more Dolby decoder chips available, and that's what
was used in all the cassette decks. This decoder circuit was
something that was developed (I don't know by who) to approximate
the Dolby playback - one size "fits" all - though I suppose not
Dolby S.
