Dolby B and C Type Noise Reduction
With cassette tapes, the most noticeable form of noise is high
frequency hiss. To reduce this hiss noise, this unit has been
equipped with a newly developed Dolby C noise reduction
system in addition to its conventional Dolby B NR. Either type
of noise reduction may be selected with the switch provided.
Dolby B NR has a noise reduction effect of about 10 dB in
the high frequency range. The corresponding figure with
Dolby C NR is about 20 dB, but this is over the entire range
where the human ear is most sensitive to noise (2 kHz to 8
kHz). Also, Dolby C NR has the same noise reduction effect
at both high and low signal levels. In addition, Dolby C NR
improves the tape’s MOL (Maximum Output Level).
Dolby noise reduction is a 2 part process that acts both on
recording and playback; be sure that the noise reduction
button is set to the same position on record and play.
*
Noise in the source material cannot be reduced with the
Dolby NR system.
