About the Dolby noise-reduction system
The Dolbynoise-reductionsystemisdesignedto effectivelyredu- ce the annoying high-frequency "hissing" noise typical of cassette tapes. During recording,the system functions to in- crease the high-frequencysound level,the sound,andthen,dur- ing playback,that same portionis weakenedto bringit backto the previouslevel.
Thisunit includestwo typesof Dolby noise-reductionsystems, the DolbyB NR-typeand 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 isreducedto about one-tenth. Usethissystemforthe recordingandplaybackofsoundsources that have a widedynamic rangeand good tonequality,such as FM broadcastsof live performances,etc., and for playingback suchtapes.
About the Dolby HX-Pro headroom
extension system
