the Dolby NR desired and also set it to the B or C TYPE MPX ON position.
However, when not recording FM broadcasts but using Dolby NR, set the
selector to the B or C TYPE MPX OFF position.
e FM stations transmit a 19 KHz pilot signal in addition to the broadcast
program. Sometimes this pilot singal may leak into the audio output
depending on the tuner and broadcast conditions. Since the 19 KHz pilot
signal is undesirable, activating the MPX filter will effectively filter out the
signal.

PLAY TRIM is a newly developed feature which functions to increase the
compatibility between this unit and tapes recorded on another deck. During
playback turn this control clockwise to boost high frequencies or turn it
counterciockwise to attenuate them. (Refer to "PLAY TRIM" section.)
BIAS ADJUST control
Turning the control counterclockwise decreases the bias and will result in
recordings with boosted high frequencies (treble). Too little bias can result in
too much or distorted high frequencies. If less distortion is more important than
high frequencies, turn the control clockwise to increase the bias signal.
(19) AUTO MODE selector

top portion of the lid in until it clicks into place. |
Ш REMOTE CONTROL OPERATION RANGE (See Fig. 4.)
The remote control transmitter uses infrared light to control the unit. Therefore,
to function properly, there must be a clear, unobstructed path between the
transmitter and the sensor on the deck. The normal operating range is about 7
meters (23 feet) and within 30 degrees perpendicular to the front panel.
E BATTERY REPLACEMENT
When the operating distance of the remote control noticeably decreases, the
batteries are exhausted. Immediately replace the batteries with new ones.
e Do not use an old battery together with a new one.
e install the same type of batteries at the same time. Do not use different kinds
of batteries (carbon, alkaline, Ni- Cad, etc.) at the same time even though
they are the same shape.
e There are two kinds of batteries in the market: rechargeable and non-
rechargeable. Read the caution labels on the battery carefully.
E BATTERY SAFETY
incorrect use of the battery can cause leakage or explosion. Proper handling
and use of batteries are as follows:
e When the remote control will not be used for an extended period of time,
remove the batteries.
e Never disassemble, heat or throw a battery into a fire.
e Do not connect (short circuit) the (+) and (-) poles of a battery with a piece

Frequency (Hz)
With cassette tapes, the most noticeable form of noise is high frequency hiss.
To reduce this hiss noise, the unit is equipped with the newer Dolby C noise
reduction system in addition to the older Dolby B NR. Either type of noise
reduction may be selected with the DOLBY NR selector.
The older Dolby B system is still very handy when playing back that extensive
library of Dolby B encoded tapes as well as recording tapes that will be played
back on a system which offers only this kind of noise reduction system (some
car, portable, and older cassette decks).
Dolby B NR has a noise reduction effect of about 10 dB in the high frequency
range. The corresponding effect with Dolby C NR is about 20 dB, but this is
over the entire range where the human ear is most sensitive to noise (2 kHz to 8
kHz). Dolby C NR also improves the tape's MOL (Maximum Output Level).
Dolby C NR has two new circuits: a spectral skewing circuit which is
responsible for a reduction in the number of encode/decode errors, and an
anti-saturation network which improves the saturation level of the tape, resulting
in reduced high frequency loss and improved dynamic range. Also, by
expanding the operating frequency range to two octaves more than that of
Dolby B NR, overall noise balance is obtained and the system also becomes
effective against high frequencies from the power supply transformer.
The graph shows the frequency response and the noise reduction effect of
recording and playback with Dolby B NR and Dolby C NR. The noise reduction
effect of Dolby C NR is larger — approximately 20 dB.
Dolby noise reduction is a 2 part process that acts both on recording and
playback; be sure that the DOLBY NR selector is set to the same position
during record and play.
Tapes encoded with Dolby NR should be decoded with their respective
systems. Nevertheless, a Dolby encoded tape can be played back without
decoding (and vice versa) with no harm to the recording. |
* Noise in the source material cannot be reduced with the Dolby NR system.

Frequency
When recording, a bias current according to the tape type used is applied to
the recording head as well as the music signal to improve the distortion rate.
Furthermore, the extreme high frequency content of a music signal can actually
act as bias, adding to the deck’s own bias signal to produce over-bias
conditions. The result is the deterioration of the high frequency components of
the music signal.
To remedy this, the Dolby HX Pro system monitors the total amount of effective
bias during recording, and instantaneously compensates for any excess bias
by reducing the deck's bias signal level accordingly. The deck operates
independently on each channel.
Since HX Pro is not a noise reduction system because it functions enly in
recording and no decoding is required, a tape recorded with the HX Pro system
can be played back on any other cassette deck while retaining the benefits of
HX Pro. |

developed by Bang & Olufsen.

E PLAY TRIM
6 J 1008 N Flat
100 1K 10kHz
Tapes recorded on one deck can be played back on another. However, slight
differences occur between any two decks such as playback frequency
response and head azimuth. This occurrence is noticeable when using the
Dolby NR system. To solve this problem, this unit incorporates a newly-
designed PLAY TRIM control. |
With Dolby NR off, the Play Trim circuit makes it possible to control the
playback frequency response by approximately +3.5 dB at 10 kHz. With Dolby
C NR on, the response compensation can extend up to more than +10 dB.
During playback, turn the PLAY TRIM control to the position which offers the
most agreeable sound quality.
~ When the high-frequency sound is distorted,turn the PLAY TRIM control
counterclockwise to attenuate the high frequencies. When the high-frequency
sound is not clear, turn the PLAY TRIM control clockwise to boost the high
frequencies.
The PLAY TRIM control is similar to the treble tone control of an amplifier. In
addition, the PLAY TRIM control functions more effectively with tapes recorded
with Dolby NR, because it functions before the Dolby NR decoder circuit.

“Turn BIAS ADJUST clockwise
This control is for fine adjustment of the recording bias. Normally it is not
necessary {o adjust this control since the deck's Auto Tape Selector
automatically adjusts the recording bias for different tape types.
Nevertheless, the deck cannot adjust for the wide range of personal
preferences nor for every brand of tape on the market (bias requirements can
vary from brand to brand). Should you feel that your recording needs further
bias adjusting (absent or distorted high frequencies), refer to the figure and
adjust this control to your tastes. |
Turning the control counterclockwise decreases the bias and will result in
recordings, with boosted high frequencies (treble). Too little bias can result in
too much or distorted high frequencies. If distortion is more important than high
frequencies, turn the control clockwise to increase the bias signal.

Ш REAR PANEL CONNECTIONS (See Fig. [5].)
Make sure that power to both the deck and your amplifier/receiver are turned
off before making any connection. |
The White plug on the paired connecting cables corresponds to the Left
channel and the Red plug corresponds to the Right channel. The LINE QUT/
PLAY jacks on the deck should be connected to the Tape PB (Playback/Input)
jacks on your amplifier/receiver, and the LINE IN/REC jacks on the deck should
be connected to the Rec Out (Rec/Output) jacks on your amplifier/receiver.
Make sure that the left and right channel connections are properly made, and
that the plugs are inserted firmly.
Connect the power cord to an AC wall outlet or to an AC outlet on the rear
panel of your amplifier/receiver (if provided).
B 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.
* YAMAHA does not recommended the use of 120 minute length cassettes
since the extreme thinness of the tape makes them susceptible to —
mechanical and recording problems.
e 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 Il/
CrO2), Ferrichrome (Type |ll/FeCr), and Metal (Type IV/METAL), and they
each require specific tape deck adjustments for optimum performance.
E AUTO TAPE SELECTOR DETECTION SLOTS (See Fig. [6].)
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 what type of tape is loaded by sensing
detector slots in the top of a tape shell. Each tape formulation has its own
characteristic hole markings which has been standardized by the tape industry.
e 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 lII/CrO2) settings. YAMAHA does not recommend
recording with this kind of tape on the deck.
e The deck does not have the required setting for Ferrichrome (Type I11/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 1/
NORM) settings. And this 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.
EM PROTECTING YOUR RECORDINGS (See Fig. [7].)
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 cassette, and it should be broken off after recording a 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 !l/CrO2) or Metal (Type IV/METAL) tapes, make
sure you do not cover the hole intended for the Auto Tape Selector
operation.
B TAKING UP SLACK IN THE TAPE (See Fig. [El.)
As a precaution against tape entanglement and damage, before inserting
cassettes into the deck, remove any slack in the tape. This is accomplished by
inserting a pencil, pen or similar object into one of the spools and gently
winding it untif 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.
BB STORING CASSETTES
After putting a cassette tape back into its case, store 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.

RECORDING
1. Make sure that the AUTO MODE selector is not set to either TIMER REC or
TIMER PLAY. Turn the POWER on.
2. Load a cassette tape to be recorded. The Auto Tape Selector determines
what type of tape is loaded, internally adjusts bias and equalization, and
indicates the optimum recording level.
3. Select the Doiby noise reduction system with the DOLBY NR selector.
When recording from an FM station with Dolby NR, set the DOLBY NR
selector to B TYPE MPX ON or C TYPE MPX ON, according to the selected
Dolby NR system.
4. Adjust the BIAS ADJUST control if desired. See "BIAS ADJUSTMENT",
5. Press the REC/PAUSE button to engage the Rec Standby mode, and play a
section of the program to be recorded. To prevent tape over-saturation, it is
best to play the loudest passage of the source and to set the recording level
based on that passage.
6. Observe the peak reading of the PEAK level meters and adjust the REC
LEVEL control so that the highest peak is between 0 dB and +6 dB (Metal
tape: +8 dB). Refer to the "SETTING THE RECORDING LEVEL" section.
Normally, it is best to adjust the BALANCE contro! so that the LEFT and
RIGHT meter readings are even.
7 Reset the source to be recorded back to the beginning. Press the PLAY
button to begin recording and immediately begin play of the source.
8. To temporarily stop the recording, press the REC/PAUSE button. To resume
recording, press PLAY button. |
9. Tostop the recording, press the STOP button.
e When the MUTE/SEARCH button is pressed during recording, a 4-second
blank interval is automatically recorded on the tape, then the Rec/Pause
mode is engaged (Auto Rec Mute). To resume recording, press PLAY
button.
e When the <4 button is pressed during recording, the tape is automatically
rewound to the point at which the recording started (Rec Return).
e When the counter is RESET to "000" during recording, and the Rec
Return function is activated, the tape will be automatically rewound to the
“000” point (0-stop).

Setting the recording level is important for proper recording. The PEAK level
meters of this cassette tape deck are equipped with optimum recording level
indicators. These indicators do away with the guess work previously
associated with setting the recording level. These optimum level! indicators
appear as lighted segments between the numbers of the signal level scale.
They automatically change position according to the tape type loaded
(determined by the Auto Tape Selector). Consequently, setting the optimum
recording level is an accurate simple operation, enabling the full dynamic
range of the tape to be exploited.
1. Load a cassette tape to be recorded.
2. Select the noise reduction saystem with DOLBY NR selector. Dot indicator
(optimum level indicator) indicates the optimum recording level.
3. Press the REC/PAUSE button to engages the Rec Standby mode, and play
a selection of the program to be recorded.
4. Watch the PEAK level meters and keep the meter reading no higher than
dot indicator (optimum level indicator) by adjusting the REC LEVEL control.
e The 0 mark indicates the Dolby noise reduction system standard level.
NOTE:
Please check the copyright laws in your country to record from records,
compact discs, radio, etc. Recording of copyright material may infringe
copyright laws.
PLAYBACK
1. Make sure that the AUTO MODE selector is not set to the TIMER operations,
then turn on the POWER switch. |
2. Open the cassette compartment by pressing the EJECT button and load a
recorded cassette tape. |
3. For a tape recorded with a noise reduction system, set the DOLBY NR
selector according to the system used in recording.
4. Press the PLAY button to start playback.
5. Set the PLAY TRIM tone control on the deck and the volume and tone
controls on the amplifier/receiver to adjust sound quality as desired,
6. To stop playback, press the STOP button.
E 0-M REPEAT PLAYBACK
With this function, the desired section can be played back repeatedly up to 8
times.
1. Set AUTO MODE selector to 0-M REPEAT position.
2. Press RESET button at the beginning of the section you want to play
repeatedly. The counter reads “000”. |
3. Press the MEMORY button at the end of the section, The MEMO indicator
lights up, and the tape immediately begins rewinding.
4. The tape is rewound until the counter has returned to the beginning of the
section. The deck then enters the playback mode.
5. The tape plays until it reaches the specified end of the section, rewinds to
the beginning, and plays again. In this way, the same selection can be
repeatedly played 8 times. After the 8th time, the deck stops. At this time
you can repeat the selection again by pressing the PLAY button.
6. To erase the memory, press the MEMORY or RESET buttons once again.
The MEMO indicator goes out.
e The length between the start and end points of the 0-M repeat section
should be more than 4 counts.
e The O0-M repeat can be carried out between a minus counter reading and
“000” (the MEMORY point before the “000” point.)
E FULL REPEAT PLAYBACK
Set the AUTO MODE selector to FULL REPEAT and start playback. The side
being played of the cassette is repeatedly played back 8 times. When the
AUTO MODE selector is set to FULL REPEAT, the FULL indicator lights.
During playback, press either of the INTRO SCAN buttons. The beginning of
each selection is played back for approximately 15 seconds in the selected
direction. Press the PLAY button once the desired selection is found. The deck
will enter the normal Play mode.
TIMER RECORDING/PLAYBACK (See Fig. ©.)
When using the AUTO MODE selector's TIMER REC or PLAY functions in
combination with a commercially available audio timer, it is possible to make
recordings and initiate playback at any time automatically.
Timer Recording
1. Make sure that all power cord connections between the timer and amplifier/
receiver are properly made. No change in any of the other connections
between deck and amplifier/receiver, etc., are necessary.
2. 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.
3. Set the timer to the desired times. It is advisable to set the timer to begin
recording slightly before and end slightly after the actual broadcast
recording time, so that you leave some room for later editing.
4. Set the AUTO MODE selector to the TIMER REC position.
5. 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
mode.
e Be sure to set this selector to OFF when not using the repeat or timer
features. If power is accidentally turned on with a cassette loaded in the
deck and the selector in the TIMER REC position, the Record mode will be
engaged and the recorded contents of the tape will be erased.
NOTE:
If the tape cannot be ejected after timer recording, turn the AUTO MODE
selector OFF and the deck's POWER switch ON. The tape can then be ejected.
Timer Playback -
All connections are the same as for timer recording.
Turn on the amplifier/receiver and adjust the Volume and Tone controls.
Set the input mode selector of your amplifier/receiver to the Tape mode.
Set the timer to the time you wish to start and stop playback.
Set the AUTO MODE selector to the TIMER PLAY position.
At the preset time, the timer will turn power on to the amplifier/receiver and
tape deck and begin playback. lt will shut power OFF at the preset time as
well, ending playback

IE CLEANING OF TAPE PATH (See Fig. 10.)
The 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
commercially available cleaning cassette and fluid type cleaners.
IB DEMAGNETIZATION
After 20-30 hours of use, enough residual magnetism will have built up on the
heads to cause poor high frequency reproduction. At this time you should use a
commercially available head demagnetizer.
e When demagnetizing the heads, be sure to follow the instructions of the
head demagnetizer carefully.
