The technical acquisitions manager at Swedish Broadcasting
told me as follows: The mini jack is not a prof standard.
Quarter inch, 6.3mm is used for headphone outputs on
all professional CD recorders. This certainly is true of
all those I have seen and used, and am likely to use in
the forseeable future. You can see this clearly on the
pics of the Tascam.

Unfortunately, in this case Arny seems to be correct - according to
Tascam's manual online at any rate. Twice, the headphone jack is
mentioned as being 3.5mm.

This particular model is obsolete, replaced, according to Tascam
again, by the BB-1000CD. An interesting product. Only of use in a
niche application I think, but for that application, just what is
needed.
