ADJUSTING THE RECORDING LEVEL
The adjustment of the recording level is the most important
factor in achieving good recording results. A high level is
good for the signal-to-noise ratio and the dynamic range,
but an excessively high level distorts the sound. If the level
is made too low for fear of sound distortion, irritating tape
hiss will mar the recording. Depending on the manufacturer
and the type of tape, the characteristics of a tape differ even
when the same kind is used, Making a setting just near the
maximum recording level for the tape type will do full justice
to the tape characteristics and result in a good-quality
recording.
Adjust the REC LEVEL control so that the level meter's
"0 dB" just lights. No harm will be done if the "+3 dB"
indicator lights momentarily at peaks. (When using metal
tapes, it is permissible for the ''+6 dB" indicator to light
momentarily.}
NOTE:
¢ The (i) mark on the level meter indicates the reference level
for the Dolby NR system.
° In reality, the optimum recording level may differ somewhat,
depending on the music source and type of tape used. In order
to deliver the best results of which your tapes are capable and
to produce better recordings, set the recording level after actual
testing, by listening carefully to the sound produced and
adjusting it to a level most pleasing to you.
* The level meter may react differently during recording and
playback of the same music tape. This is due to differences in
tape sensitivity, and creates no problem so long as the variation
is not severe.
This unit features a dual noise reduction system (Dolby NR
B and C systems).
Dolby NR system
The Dolby NR system is designed to reduce the amount of
tape hiss, mainly in the treble components. During recording,
the high-pitched pianissimo sounds which are most
characteristic
of audible noise
are boosted,
and during
playback these boosted sections only are attenuated so that
the tape sound is returned to normal. As a result, the noise
is attenuated by an amount equivalent to the boosting in
the treble range.

The Dolby NR B system serves to reduce noise in the treble
range by cutting tape hiss and expanding the dynamic range.
The Dolby NR C system is even more effective than the B
in reducing noise as it cuts the noise from the mid-range on.
