About thft Dolb^ noise-reducHon systenrr
T!ie Dolby noise-reduction system is designed to effectively reduce
the tinnoying high-frequency "hissing" noise which can occur with
cassette tapes. During recording, the system functions to increase
the high-frequency sound level, and then, during playback, that
same pt)rtion is weakened to bring it back to the previous level.
This unit includes two types of Dolby noise-reduction systems, the
Dolby B NR-type and C NR-type.
Dolby B-type noise-reduction
Noise is reduced to about one-third.
Use this system when playing back tapes recorded 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 sound 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.
BI SB
By functioning improve the maximum output level of the tape's
high-frequency range, this system permits recording without a
reduction in the level of the sound source's high-frequency range.
In addition, by using the system in parallel with this unit's noise-
reduction system, recording anci playback with a greatly extended
dynamic range is possible.
