Common modes of operation
ag
ee
Check once again that all connections have been completed ex-
actly as indicated in the connections diagram and then turn the
power on. After turning power on, no operations are possible until
the recording indicator has stopped flashing on and off.
Inserting Cassettes
1.
Depress the Eject button [fi] to open the cassette holder [i0}.
2.
Insert a cassette with the exposed tape facing down and the
side to be played facing outward.
3.
Close the cassette holder.
Tape Playback
Set the Dolby NR switches [3] to the proper position for the
tape about to be used. Tapes recorded using Dolby B or C NR
must be played back with the Doiby NR switch on the left in
the ON position and the one on the right in the B or C posi-
tion. Tapes recorded without Dolby NR must be played back
with the left Dolby NR switch in the OFF position.
2.
Press the [> PLAY button to begin playback. The Peak Level
indicators [8] will light during playback showing the strength
of the recorded signal.
3.
Press the If PAUSE button to interrupt playback temporarily.
To continue, press the [> PLAY button again.
4.
The auto-stop mechanism will automatically stop tape
transport if a tape is played through to the end. To stop
playback at any other time, press the IJ STOP button. After
tape transport has stopped and the Peak Level indicators
have gone out, press the Eject button [11] to open the cassette
hoider and remove the cassette.
Note:
The position of the Accubias Control knob has no effect on
playback sound quality.
Fast Forward and Rewind
Press the P> button to wind the tape rapidly forward and the <<
button to wind it rapidly backward. The tape will stop when the i
STOP button is pressed or when the end of the tape is reached
(on account of the auto-stop mechanism).
Recording
1.
Insert a cassette with the side to be recorded facing out.
Before inserting the cassette, confirm that the erasure preven-
tion tabs are intact (see page 6). If one or both of the tabs is
broken off, recording on the side with the missing tab will not
be possible.
4.
Set the Dolby NR switch [3] on the left to the ON position and
the one on the right to the B or C position if you wish to make
a Dolby NR encoded recording. Refer to the section "How to
Use the Dolby NR Switches" on page 4 for details.
5.
Press the COUNTER RESET button [9] to return the tape
counter to [000] so you can index the recording for future ref-
erence.
6.
Set the Input Level Control knobs [6] for both the left and right
channels to their center positions. Press the I PAUSE button
while holding the @ REC button down. The tape will not
move, but the Peak Level indicators [8] will show the level of
the signal being received through the Line In jacks [f3].
7.
While watching the Peak Level indicators [8], adjust the Input
Level Control knobs [6] to the proper position.
8.
Usually, the stereo balance will be correct if you set both
knobs to the same position. However, if there is a large dif-
ference between the levels shown by the left and right chan-
nel Peak Level indicators, set the knobs at different positions
so that the input levels for both channels are approximately
the same.
9.
Confirm again that an input signal is being received (the Peak
Level indicators should light) and then press the [> PLAY but-
ton to begin recording.
The auto-stop mechanism will stop tape transport automat-
ically when the end of the tape is reached. To stop recording
before the end of the tape, press the ll STOP button. To brief-
ly interrupt recording, press the Il PAUSE button.
10.
Notes:
1) If the [> PLAY button is pressed while the @ REC button is
being held down, recording will begin immediately. Always
remember to set the Input Level Control knobs [6] to the
proper position before starting recording.
2) The deck will not switch to the recording mode if the @ REC
button is pressed after the (> PLAY button.
Setting the Proper Recording Level
The recording fevel has an important effect on the sound quality a
tape will have when it is played back. A recording level that is too
high will cause distortion while one which is too low will lower the
signal-to-noise ratio resulting in a tape with excessive "hiss
noise." It is particularly important to set the recording level correct-
ly with cassette tapes since they have a much thinner magnetic
coating than open reel tapes. The thin coating gives the tape a
comparatively low saturation level which can easily be surpassed
if the recording level is set too high. To obtain the best results
with this deck, adjust the Input Level Control knobs [6] while
watching the peak level meters to be sure the setting is neither
too high nor too low. The top eight segments of the peak level in-
dicators (-10dB— +6dB) feature a peak hold function.
e With metal tape formulations, the Input Level Control knobs
should be adjusted so that the +3dB indicators light up from
time to time. With all other kinds of tapes, the + 1dB indicator
should only light up from time to time.
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 anti-saturation 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. To use Dolby B or C NR, first depress the Dolby NR switch on
the left [3] to the ON position.
2.
Next select Dolby B or C NR with the Dolby NR switch on the
tight. The in position is for Dolby C and the out position for
Dolby B.
