DOLBY S NR
DOLBY S NR is developed incorporating the concept of
professional-use DOLBY SR system into the present
DOLBY B/C NR.
It offers the noise reduction effect increased by about
40%, compared to the former DOLBY C NR, and also the
noise level of the low frequency range is reduced to 1/3.
Highly natural sound can be reproduced with the help of
the modulation controller, which regulates 5 NR units —2
for low level sounds and 3 for high level, one of which is
for low frequency signals.
DOLBY S NR has also high interchangeability. The tapes
recorded with DOLBY S NR can well be reproduced by
the decks which are equipped only with DOLBY B NR,
headphone stereos or car stereos for example.

Linear time tape counter and the tape length
setting
Use the linear time tape counter as an aid in locating a
point on a tape (–99 min. 59 sec. to 99 min. 59 sec.). To
set the counter reading to "0:00", press the COUNTER
RESET button. This counter is not an actual clock.
Rather, it is a counter with minutes and seconds divisions
when the tape length of the tape to be used is memorized.
To memorize the tape length, press the TAPE button so
that the desired tape length appears on the display. The
tape length can be set to C-46, C-50, C-54, C-60, C-70,
C-80 or C90.
Note: Precision of counter
The tape counter is not a clock, and so there will be
some errors in the time display compared to the actual
playing time (this cannot be avoided, as a suitable
method is adopted to provide a time display not only
during recording and playback, but also during fast
forward and rewind). The error depends on the type of
tape being used.
To display the remaining time
Press COUNTER REMAIN button so that the REMAIN
indicator lights. The remaining time appears in the display
a few seconds after pressing the PLAY button to start
playback. Press again to return to the elapsed time.
÷It is necessary to memorize the tape length with the

Tape counter and COUNTER RESET button*
Before starting recording, press the COUNTER RESET
button to set the counter reading to “0:00”. Use this
counter to aid in locating a point on a tape.
It is necessary to memorize the tape length for accurate
calculation of elapsed tape time and remaining tape time.
To memorize the tape length:
Press the COUNTER TAPE button. Each time the button
is pressed, the display will change from “C-46”, “C-50”,
“C-54”, “C-60”, “C-70”, “C-80”, to “C-90”and the last tape
length to be displayed is memorized.
To display the remaining time*:
Press the COUNTER REMAIN button during recording. If
the tape length is already memorized by the TAPE button,
the unit will compute and display the remaining available
recording time.
Press again to return to the elapsed time counter reading.
(This button is also used during playback.)
* Note: Precision of counter
The tape counter is not a clock, and so there will be some errors
in the time display compared to the actual recording time (this
cannot be avoided, as a suitable method is adopted to provide a
time display not only during recording and playback, but also
during fast forward and rewind). The error depends on the type
of tape being used.

÷MPX filter:
FM stations transmit a 19 kHz pilot signal in addition to
the broadcast program. Sometimes this pilot signal may
leak into the audio output depending on the tuner and
broadcast conditions. This signal can cause improper
operation of the Dolby NR systems. Activating the MPX
filter (B TYPE/C TYPE/S TYPE MPX ON settings) will
effectively remove the signal.
AUTO TAPE TUNING button (in step 4)
Pressing this button during the REC/PAUSE mode will
activate the Auto Tape Tuning that makes it possible to
internally determine the optimum recording characteristics
(bias and recording sensitivity) according to the loaded
cassette tape in about 15 seconds.
To perform the Auto Tape Tuning, send the tape leader
part forward and set the PLAY/TRIM control and the BIAS
ADJUST control to the center position before pressing the
AUTO TAPE TUNING button. When the Auto Tape Tuning
is completed, the TAPE TUNING indicator lights. After
completion of Auto Tape Tuning, the tape automatically
rewinds to the point where the Auto Tape Tuning began
and the REC/PAUSE mode is engaged. The bias
adjustment with the BIAS ADJUST control is possible even
after this tuning.
To clear Auto Tape Tuning setting, press the AUTO TAPE
TUNING button once again, or load any cassette tape of
different type.
* When recording on the other side of the tape, another
Auto Tape Tuning is unnecessary.
When recording on the same type cassette tape of a
different brand, another Auto Tape Tuning is advisable
for much more accurate setting of the recording
characteristics.
AUTO TAPE TUNING
The Auto Tape Tuning function improves the quality of
your recording, permitting critical adjustment of the
deck’s recording bias and sensitivity for best results
with every tape you use.
With the Auto Tape Tuning function, the recording
characteristics (recording bias and sensitivity) are
automatically adjusted while recording and playback
operations in about 15 seconds, to accurately match
the characteristics of loaded tape.
For example, the recorded (output) level (Ain the
figure) may differ from recording (input) level (Bin the
figure), due to widely varying characteristics of
cassette tapes between brands.
Using the Auto Tape Tuning function, these differences
are effectively eliminated by adjusting the recording
bias (for high frequencies) and sensitivity (for overall
frequencies) according to the loaded cassette tape,
making a significant contribution to overall recording
quality (Cin the figure).
DOLBY HX PRO DYNAMIC BIAS SERVO SYSTEM
This unit incorporates the Dolby HX Pro system which
automatically controls the effective bias to reduce
distortion and noise, improving high frequency
response during recording. Tapes recorded with this
system retain the same high quality even when played
back on any other cassette deck.

14
Setting the recording level (in step 5)
Play the loudest passage of the source to be recorded
and watch the meter readings. Adjust the REC LEVEL
control so that the highest peak may not exceed the
optimum levels of each tape type. Normally, it is best to
adjust the BALANCE control such that the LEFT and
RIGHT meter readings are even.
Three head system
The three-head system allows the just-recorded sound to
be monitored while recording. You can compare the
difference between the recorded sound and the source
sound by switching the monitor mode (SOURCE or TAPE)
with the MONITOR button, so you can try to obtain a
recording sound identical to the source sound.
Synchronized recording function
When operating this unit in combinaton with the YAMAHA
CD Player which has SYNCHRO button on its remote
control transmitter, CD Synchronized recording function
can be utilized. This function is operated with the remote
control transmitter of the CD Player. (Regarding the
operation, refer to the instruction manual of the CD
Player.)
SYNCHRO indicator of this unit lights when the SYNCHRO
button of the remote controller is pressed.

For details, refer to the instructions of your audio timer.
No change in any of the other connections between the
deck and amplifier/receiver, etc., is necessary.
With a commercially available audio timer it is possible to
make recordings and initiate playback automatically at
any time.
Make sure that all power cord connections between the
timer and amplifier/receiver are properly made.
TIMER RECORDING/PLAYBACK
1. After turning on the power to each component, select
the station on your tuner which you want to record and
turn down the volume on your amplifier/receiver. This
will have no effect on the recording signal level.
Remember to set the proper recording level.
2. Set the timer to the desired recording start and stop
times. It is advisable to set the timer to begin
recording slightly before and end slightly after the
actual broadcast receiving time to leave some room
for later editing.
3. Set the TIMER switch to the REC position.
4. The timer will send power to the amplifier/receiver,
tuner and deck at the preset time, turning all the
components on and initiating the recording.
1. Turn on the amplifier/receiver and adjust the volume
and tone controls.
2. Set the input mode selector of your amplifier/receiver
to the cassette deck function mode.
3. Set the timer to the time you wish to start and stop
playback.

TYPE II TYPE IV
CASSETTE TAPES
CASSETTE TAPES
There are many different types of cassette tapes
available. However, they all conform to standard
specifications so any brand may be used with the deck.
÷Classification of Cassette Tapes by Formulation
Cassette tapes are available in four basic types
depending on their formulation, or type of magnetic
material and manufacturing process. These four types
are commonly known as Normal (Type I/NORM),
Chrome (Type II/HIGH <CrO2>), Ferrichrome (Type III/
FeCr), and Metal (Type IV/METAL), and they each
require specific tape deck adjustments for optimum
performance.
* YAMAHA does not recommend the use of 120 minute
length cassettes since the extreme thinness of the tape
makes them susceptible to mechanical and recording
problems.
AUTO TAPE SELECTOR DETECTION SLOTS
The deck has a built-in Auto Tape Selector which
automatically adjusts for the proper bias, level and
equalization according to the tape formulation —all you
have to do is load a cassette and the Auto Tape Selector
does the rest.
The Auto Tape Selector determines which type of tape is
loaded by sensing detector slots in the top of the tape
shell. Each tape formulation has its own characteristic
hole markings standardized by the tape industry.
÷Early model Metal (Type IV/Metal) tape formulation
cassette shells do not have the slots for Auto Tape
Selector operation. As a result, early model Metal type
tapes recorded on another deck will be played back
with the deck at the Chrome (Type II/HIGH <CrO2>)
settings. YAMAHA does not recommend using this kind
of tape.
÷The deck does not have the required setting for
Ferrichrome (Type III/FeCr) tape, since this tape
formulation is not widely used. Should you use a
Ferrichrome tape, it will be recorded and played back at
the Normal (Type I/NORM) settings, which will result in
an unnatural high frequency emphasis. This effect may
be compensated for somewhat by adjusting the BIAS
ADJUST to the plus (+) direction during recording, or by
using the PLAY TRIM tone control and/or the tone
controls of your amplifier/receiver during playback.
PROTECTING YOUR RECORDINGS
All cassette tapes are provided with erasure protection
holes to prevent accidental erasure of recorded contents.
There is a small tab covering the hole on each side of the
cassette, and it should be broken off after recording the
tape. Without this tab covering the hole, it is impossible to
record onto that tape. Thus, you can safely protect a
recording for as long as you wish without fear of
accidental erasure. Should you wish to use a cassette
tape protected in this way for recording, simply covering
the hole with adhesive tape will permit erasure and re-
recording.
÷When using Chrome (Type II/HIGH <CrO2>) or Metal
(Type IV/METAL) tapes, make sure you do not cover the
hole intended for the Auto Tape Selector operation.
STORING CASSETTES
After putting a cassette tape back into its case, store it in
a location away from exposure to direct sunlight, humidity,
high temperatures, and magnetic fields (away from
television sets, speakers, etc.). High temperatures and
humidity will damage the tape itself, while exposure to
magnetic fields may cause a loss of recorded material.
Avoid touching the tape surface with your fingers, since
dirt or finger oil will contaminate the deck’s heads.
TAKING UP SLACK IN THE TAPE
As a precaution against tape entanglement and damage,
remove any slack in the tape before inserting cassettes
into the deck. This is accomplished by inserting a pencil,
pen or similar object into one of the spools and gently
winding it until all the slack is removed. You do not have
to wind it too tightly.
Be careful not to touch the tape part itself. It is very
delicate and touching it may damage the tape and its
recorded contents.

MAINTENANCE
DEMAGNETIZATION
After 20-30 hours of use, enough residual magnetism will
build up on the heads to cause poor high frequency
reproduction. At this time you should use a commercially
available head demagnetizer.
÷When cleaning the tape path or demagnetizing the
heads, be sure to follow carefully the instructions of the
concerning materials such as cleaning fluid or head
demagnetizer.

CLEANING OF THE TAPE PATH
Continued high quality performance of your deck is
dependent upon periodic cleaning of the heads, capstan,
pinch roller, and all surfaces over which the tape travels.
Normal use will cause an accumulation of dirt and dust on
the heads, capstans, and pinch rollers. This can lead to
poor sound quality, drop outs (intervals with no sound),
unsteady tape speed, loss of high frequency response,
etc.
Thus, clean the heads and all surfaces over which the
tape travels with a commercially available cleaning
cassette and fluid type cleaner.
