Dolby HX is not a NR. It is headroom expansion and was devloped by B&O
for their cassette decks and now through Dolby to other makes. I don't really
know more than that, sorry.
Dolby SR *probably* means Dolby Surround Sound, some new 'hip' thing for
better sound, not NR.

Dolby HX works by adjusting the bias signal on your tape deck during
recording. There is no playback circuitry. It is used in most
high end cassette machines and by commercial duplicators.
Since it is in the bias chain, it can not be added on with an outboard
unit. BTW, I have it on my home cassette and it makes a big difference
in the sound.

| I also have "HX Pro" (it's full name) on my AIWA dubbing deck.
I can't tell you how much of a difference it makes since unlike
Brian's deck, it's not defeatable via an in/out switch (you
always get HX Pro), but tapes made with that deck really do sound
much better than I would have expected for a cassette deck.
The combination of HX-Pro and dbx (my deck also has B and C [and none])
produces very very good recordings. Just wish it had double speed
recording.

I believe the SR in Dolby SR stands for Spectral Recording. It's
the latest generation in Dolby NR for studio recording. Last time
I heard it was in the neighborhood of $2,000 per channel. It claims
to give analog tape the S/N and dynamic range of digital recording,
without the grunge.
