ADJUSTINGTHERECORDINGLEVEL
The adjustment of the recording levelisan important factor in achiev-
ing good recordingresults.
A high level isgood for the signal-to-noise
ratioand the dynamic range but an excessivelyhigh level
distortsthe
sound. lf the levelis made too low out of fear of distorting the sound,
irritating
tape hiss will marthe recording.Dependingon the manufac-
turer and type of tape, the characteristics
of a tape differ even when
the same kind is used. Making a setting to just nearthe tape's max-
imum recordinglevelwill do full justice to a tape's characteristicsand
result in a good-quality recording.
When INPUT level controls can also be used to fade in the sound
where the recording level is gradually increased or to fade out the
sound where the level is gradually reduced.

Thetapehiss

Thisis
particularly
thecase in pianissimo

sections
where

for
instance,are

TheDolby
noise
reduc-
tion system
was developed
in order
to reduce
thistapehiss.
The
Dolbytype B system
isalready
widelyused
for noise

but
thisunit

During

creaseand
thesoundisplayed

Thisoperation
isperformed

inaccordance
withthe
strengthof theinputsignals,
and
it ispossible
to improve
the
signal-to-noise
ratioatfrequencies
over
5 kHz
byabout
10
dB.As a
result,the system
is really effective
for the recording
andplayback
of ordinarybroadcasts
and records,
etc.
However,whenrecording
a program
source
witha wide
dynamic
range,a greater reduction
inthe noiseisrequired.
lt was
forthis
reason
that the Dolbytype Csystem
wasdeveloped'
The big difference
between
type B andtype C isthat the improve-
mentinthe high-frequency

AND CAPSTAN
The heads,

parts
easily
contaminated by dirt, dust, and oil during tape travel. Dirty headsin
particular result in poor tape-to-head contact, causing poor sound
quality, upsetting stereo balance, and causing fluctuations in tape
speed.Clean
the headsregularly
with special head-cleaning
swabs, or
a soft cloth dipped in cleaningfluid.
1. Open the head cleaning accessport.
2. Set the POWER switch to ON.
3. Pressthe PLAY switch. The head base will rise and the pinch
rollerswill begin rotating.
4. Moisten a cleaning swab lightly with cleaning fluid, and gently
wipe the heads, pinch rollers,
and capstans.
NOTE:
. After cleaning, do not load a tape (for 2 to 3 minutes) until the
cleaning fluid has dried.
. Set the stereo amplifier's volume control to the minimum posi-
tion when cleaning the heads.
