Recording an FM broadcast with
DOLBY B NR
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 20 seconds, to accurately match
the characteristics of loaded tape.
For example, the recorded (output) level (A in the
figure) may differ from recording (input) level (B in 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 (C in the figure).

÷ 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 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

(bias and recording sensitivity) according to the loaded
cassette tape in about 20 seconds.

To perform the Auto Tape Tuning, send the tape leader

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.

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 manual of the CD Player.)
SYNCHRO indicator of this unit lights when the SYNCHRO
button of the remote controller is pressed.
Bias adjustment
The BIAS ADJUST control is for fine adjustment of the
recording bias. Normally, it is not necessary to adjust this
control since the recording bias can be automatically
adjusted by the built-in Auto Tape Selector and the AUTO
TAPE TUNING button for different tape types.
However, if you feel that your recording needs further bias
adjustment (to compensate for absent or distorted high
frequencies), adjust this control to your liking.
When high frequencies are
distorted, increase the
recording bias by turning
the BIAS ADJUST control
clockwise.
When high frequencies are
absent, decrease the recording
bias by turning the BIAS
ADJUST control
counterclockwise.

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.
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.
4. Set the TIMER switch to the PLAY 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.
Note: Whenever the timer recording/playback is not
intended, make sure to set the TIMER switch to OFF
position to prevent the unnecessary recording/playback.
÷ If the TIMER switch is set to REC position and the
power is supplied (plugging in the power cord or
automatically supplying the power after power failure,
etc.), the deck automatically enters Rec mode and the
contents of the cassette tape inserted in the deck will
be erased.

CASSETTE TAPES
CASSETTE TAPES
PROTECTING YOUR RECORDINGS
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.
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.
*
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 control and/or
the tone controls of your amplifier/receiver during
playback.
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.
TYPE II
TYPE IV
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.

MAINTENANCE
Inside of the cassette compartment
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.
Heads
Capstan
Pinch roller
Thus, clean the heads and all surfaces over which the
tape travels with a commercially available cleaning
cassette and fluid type cleaner.
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.
