comparatively low saturation level which can easily be surpassed
The Dolby Noise Reduction Systems
Dolby B NR is the system used in most cassette tape decks to
reduce the background noise that is inherent in all cassette tapes.
Dolby Laboratories then developed an even more effective noise
reduction system, Dolby C NR, in response to the demand for in-
creasingly better sound quality from cassette tapes.
Both Dolby noise reduction systems operate by boosting signals
during recording that fall below a certain input level. Dolby B and
C NR operate on the higher portions of the frequency spectrum
using what is called a "sliding band" technique. This is because
tape hiss is most prominent during the quiet, high frequency por-
tions of a recording. These same signals are then reduced back to
their original strength during playback, thereby reducing the back-
ground noise by the same amount. In order to operate only when
necessary, the Dolby NR system has a varying effect depending
on the input level and frequency of the material being recorded.
Dolby C NR is capable of reducing tape hiss by 10dB more than
Dolby B NR. In addition to its noise reduction function, Dolby C
NR has an antisaturation network that lowers high input levels
before recording them and returns the signals to their original
strength during playback. This raises the high-frequency satura-
tion level of cassette tapes to allow you to record signals that
would normally cause distortion. This system raises the maximum
output level of cassette tapes by more than 4dB at 10kHz.
How to Use the Dolby NR Switches
1. Touse Dolby B or C NR, first depress the Dolby NR switch on
the left [15] to the ON position.
Next select Dolby B or C NR with the Dolby NR switch on the
right [15]. The in position is for Dolby C and the out position
for Dolby B.

The Dolby HX Pro System
Tape sensitivity is constantly changing as recordings are made
due to the biasing effect of high frequency audio signals. Dolby
HX Pro is a system that compensates for these undesirable fluc.
tuations during recording. It does not operate during playback, s
cassettes recorded with Dolby HX Pro can be played back on
decks not equipped with the system.
