About the Dolby noise-reduction
system
The Dolby nolse-reduction system is designed to effectively redu-
ce the annoying high-frequency “hissing” noise typical of
cassette tapes. During recerding, the system functions to in-
crease the high-frequency sound level, the sound, and then, dur-
ing playback, that same portion is weakened to Dring it back to
the previous !evel.
This unit includes two types of Dolby noise-recucticr systems.
the Dolby B NR-type and C NR-type.
Doiby B-type nofse-reduction
Noise is reduced to about one-third
Use this system when playing back tapes recoded by the Dolby.
B noise-reduction system, such as prerecorded music tapes. etc.
Dolby C-type noise-reduction
Noise Is reduced to about one-tenth
Use this system for the recording and playback of sourd sources
that have a wide dynamic range and good tone quality. such as
FM broadcasts of live performances, etc., and for playing back
such tapes.
‘About the Dolby HX-Pro headroom
extension system
By functioning to improve the maximum output leve! of the {ape's
high-frequency range, this system permits recordings without a
reduction in the level of the sound source’s high-frequency
range. In addition, by using the system in parailel with this unit's
noise-reduction system, recording and ptayback with a greatly ex-
tended dynamic range is possible.
