DOLBY S NR
DOLBY S NR is developed incorporating the concept of
professional-use DOLBY SR system into the present
DOLBY B/C NR.
It offers the noise reduction effect increased by about
40%, compared to the former DOLBY C NR, and also the
noise level of the low frequency range is reduced to 1/3.
Highly natural sound can be reproduced with the help of
the modulation controller, which regulates 5 NR units — 2
for low level sounds and 3 for high level, one of which is
for low frequency signals.
DOLBY S NR has also high interchangeability. The tapes
recorded with DOLBY S NR can well be reproduced by
the decks which are equipped only with DOLBY B NR,
headphone stereos or car stereos for example.
