O MPX FILTER switch
Press this switch to the ON position when recording broadcasts from FM
stations while using a Dolby NR system.
Set this switch to OFF when recording sources other than FM broadcasts, and
during playback of any tape, even a recording of an FM broadcast.
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 will
effectively remove the signal.
» DOLBY NR switches
OFF/ON switch:
Set this switch to the OFF position if no noise reduction is desired. In the OFF
position, signals do not pass through the noise reduction circuits and are
output unprocessed. |
Sel the switch to ON position if Dolby noise reduction is desired.
B TYPE and C TYPE switches:
When playing tapes encoded with Doloy NR or making recordings to be
encoded with Dolby NR, set this switch to the desired type of Dolby noise
reduction B TYPE or C TYPE, and set the OFF/ON switch to ON. The
corresponding indicator in the display will light.
© Dolby noise reduction is an extremery effective method of reducing
undesirable background hiss on tapes. This unit incorporates both Dolby B
NR and the newer Dolby C NR systems. The newer Dolby C NR is
approximately twice as effective as the earlier Dolby 3 NR.
0) PRESET REC LEVEL LEFT and RIGHT controls
These controls are used to adjust and set the recording levels for the LEFT and
RIGHT channels. Turning a contro! clockwise increases the recording level,
and turning it counterclockwise decreases the recording level. For optimum
recording level settings, see “SETTING THE RECORDING LEVEL”.
U AUTO MODE selector
OFF: For normal playback or recording, set to this position.
FULL REPEAT: In this position (the FULL REPEAT indicator lights), one side
of the cassette can be repeatedly played back 8 times from beginning to
end.
0-M REPEAT: With the selector set to this position (the 0-M REPEAT indicator
lights), the section between “0.00” on the linear counter and the counter
number memorized with the MEMORY button (the MEMORY indicator lights)
is repeatediy played 8 times (this section must be at least 5 seconds long).
However, if the MEMORY function is not activated (MEMORY indicator is off)
but the 0-M REPEAT is selected, any rewinding and fast forwarding of a tape
will stop at the display reading of “0,00”.
TIMER PLAY: By using a commercially available audio timer, this function
permits timer activated playback.
TIMER REC: By using a commercially available audio timer, this function
allows you to carry out unattended recording.
* Be sure to set this selector to OFF when not using the repeat playback
feature or the timer feature. if power is 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 prerecorded contents of the tape will be erased.
@ BIAS ADJUST control
This control is for fine adjustment of the recording bias. Normally it is not
necessary to adjust this contro! since the decks Auto Tape Selector
automatically adjusts the recording bias for different tape types.
Nevertheless, the deck cannot adjust for the wide range of personal
preferences or 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 "BIAS
ADJUSTMENT" section 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 ir
foo much or distorted high frequencies. If less distortion is more important th
high frequencies, turn the control clockwise to increase the bias signal.

OTE CONTROL OPERATION RANGE (See Fig.
The remote control transmitter uses harmless 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. |
When the operating distance of the remote control noticeably decreases, the
batteries are exhausted. Immediately replace the batteries with new ones.
e Replace old batteries with fresh ones. 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.
® There are two kinds of batteries in the market: rechargeable and non-
rechargeable. Read the caution labels on the battery carefully.
44
E BATTERY SAFETY
Incorrect use of the battery can cause leakage or explosion. Proper handling
and use of batteries are as follows:
® When the remote control will not be used for an extended period of time,
remove the batteries.
® Never disassemble, heat or throw a battery into a fire.
® Do not connect (short circuit) the (+) and (~) poles of a battery with a piec
of wire, metal, etc. In case of leakage, thoroughly wipe off all the electrolyt,
from the battery compartment and install new batteries.

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 and an anti-
saturation network. By improving the saturation level of the tape, it is possible to
prevent high frequency loss, encode/decode error, etc., and improve dynamic
range, signal-to-noise ratio, and make it easier to set the recording level.
With Dolby C NR, it is possible to achieve the same noise reduction effect at
both high and low signal levels and to set the recording level to a point where
negative side effects are eliminated. 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 switch 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 r 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 only 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.

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. To solve this problem, this unit incorporatés a
newly designed PLAT TRIM control. —
Fig. shows the frequency response curve for recording and playback on
this deck. The PLAY TRIM circuit makes it possible to control the playback
frequency response by approximately +3.5 dB at 10 kHz.
Fig. shows the frequency response curve for playback on this deck of a
tape recorded on a deck with Dolby NR ON. When Dolby C is ON, the
response compensation can extend up to more than +10 dB. The figure shows
a drop of 10 dB in the frequency response at 10 kHz. However, in some cases,
the high frequency response is emphasized. By adjusting the PLAY TRIM
control, music tapes recorded on other decks can be played back without high
frequency degradation.
Fig. @) shows the frequency response curve for playback on this deck of a
tape recorded on a deck with Dolby NR OFF. The figure shows a drop in the
high frequency response at 10 kHz. But in some cases, the high frequency
response is emphasized.
The PLAY TRIM control is similar to the treble tone control of an amplifier, and
is characterized by the fact that it can be controlled even when Dolby NR is
ON, because it functions between the playback equalizer and the Dolby NR
decoder circuits.
During playback, slide the PLAY TRIM control to the position which offers the
most agreeable sound quality.

~ This control is for fine adjustment of the recording bias. Normally it is not
necessary to 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

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 hig
frequencies, turn the control clockwise to increase the bias signal.
El REAR PANEL CONNECTIONS (See Fig. &
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).
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 Cassettes 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 |/NORM), Chrome (Туре
{1/CrO2), Ferrichrome (Type |!1/FeCr), and Metai (Type IV/METAL), and
they each require specific tape deck adjustments for optimum performance.
# AUTO TAPE SELECTOR DETECTION SLOTS (See Fig.
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.
@ Early model Metal (Type IV/Metal) tape formulation cassette shells do not
