DOLBY B AND C NOISE REDUCTION SYSTEM

í The Dolby noise reduction system substantially reduces the tape
background noise (hiss) inherent in the cassette medium.
í Tape background noise consists primarily of high frequency
information, which is particularly annoying during soft passages,
The Dolby NR system increases the level of low volume mid and
high frequency signals during recording and reduces the level of
these signals by an identical amount during playback, As a result,
the playback signal is identical to the original source, but the level
of background noise generated by the tape is greatly reduced.

5. Start edit playback of the CD player. (The operation procedure
may be variable between CD players with edit function. Refer to
the instruction manual of your CD player.)
¼ When the MARANTZ CD-57, CD-67 or CD6000 CD player is used,
be sure to set the REV. MODE switch to "=". (This causes both
tape sides A and B to be recorded automatically.)
¼ When other MARANTZ CD player than the above mentioned
models is used, set the REV. MODE switch to "=". (This causes
only tape side A or B to be recorded.)
¼ During recording and playback operations, the counter is useful
for noting the location of existing programs or positions where
recording is to be started.
¼ The reading of this counter does not correspond with that of any
other deck.
í The operating principle of Dolby C NR is similar to that of Dolby B
NR except for the encoding/decoding response curves. The noise
reduction effect obtained with Dolby C NR is up to 20 dB,
compared to 10 dB with Dolby B NR. In addition, Dolby C NR uses
an anti-saturation network and spectral skewing circuitry for a
significant improvement in the dynamic range of the mid-to high-
frequencies.
