1.5.5 Dolby noise reduction system”
Dolby-B:
The Dolby-B noise reduction system increases the level
of the weak signals in the mid and high frequency range
during the recording process, and correspondingly
deemphasizes these signals during playback. The play-
back corresponds exactly to the original sound, but the
tape noise will be reduced.
Dolby-C:
The
Dolby
C
noise
reduction
system
is
similar
to
Dolby
B.
However,
the
range
in
which
Dolby
C
emphasizes
the
level
during
the
recording
and
deemphasizes
the
level
during
playback
is
much
larger,
which
results
in
superior
noise
reduction.
1.5.6 Calibration
The factory optimizes the cassette deck alignments to
the cassette types specified in the "Technical data".
When the cassette is inserted, the tape type is automati-
cally selected and shown on the display segment [G].
The BIAS and CALIBRATION potentiometers are used
for adjustment to different batches of the same cassette
brand, as well as to different brands of cassettes type |
and fl.
With CALIBRATION the source/tape level can be ad-
justed to identical values based on the level indication [K]
on the display.
With BIAS you can align to identical treble reproduction.
Comparison is possible by changing over between
SOURCE / TAPE in record mode. As a test signal the
noise of an FM tuner (without signal and without muting),
or any other high-frequency audio source can be used.
