FEATURES

Transport Section Engineered for Stable Tape Run

This deck features the closed loop dual capstan system whereby
a capstan is stationed on either side of the heads. This system
maintains a stable contact between the heads and the tape so that
the tape travels at a constant tension all the time, and it also helps
to suppress dropouts in the tape and fluctuations in the level.
Another important point is that external vibration transmitted from
the reel bases and tape guides to the tape is kept down to the
minimum for a marked reduction in the modulation noise and both
recording and playback which are faithful to the original sound.

The DC servo motor which provides a stable rotational speed is
combined with the ultra-precision-engineered capstans and good
dynamic balance flywheels to yield a truly superior tape transport
performance, and a great improvement in the wow and flutter
characteristics.

Yet another prime feature is the mechanical governor motor
with its powerful rotation torque and less ripple. This Is used for
the takc»up operations, and enables reliable fast forward and
rewind operations.

Three-Head System with Recording/Playback
Combination Head

This deck adopts a recording head and a playback head which
are combined to fit neatly into a single case as a tidy package. Each
head is made of a sendust core and this makes it possible to exploit
the features of both metal tapes, chrome tapes and ferrichrome
tapes to the full. The heads are provided with a high level of resist-
ance to wear and are tailored to produce tap-notch distortion
characteristics with high input signal levels as well as an excellent
frequency response and signal-to-noise ratio. The contact between
the heads and the tape is surefire and firm and the adhering of dust
and generation of noise caused by magnetization are reduced to the
minimum. These are just a few of the amazing powers of the heads.
What's more, the combination head can be used to monitor a
recording virtually in real time if the playback head is put to work
while you are recording.

Digital Bar Graph Display Level Meter

This dccks level meter features two bar graph fluorescent
display tubes and it functions with all-electronic digital control.

The meter can naturally be used for ordinary VU display and an
added convenience is that it can be used as a peak meter with a fast
response time for detecting pulsing sound accurately. The level
meter mode can be selected in accordance with the program source
which you intend to record, and it facilitates the setting of the
recording level corresponding to the contents of the actual pro-
grams.

Tape Selector and Bias Control to Do Full Justice
to the Performance of Every Kind of Tape

The most is made of not only metal tapes but also chrome tapes,
ferrichrome tapes and standard tapes with the tape selector which
selects the equalizer and bias corresponding to the type of tape
used and also with the bias control which allows the bias of the
tape to be finely adjusted. Adjustments can therefore be made to
suit the characteristics of each type of tape. The bias control can
also be used to produce the frequency response of your preference.

Soft Push-type Tape Mode Selector Switches

Soft push-type electronic controls are adopted in the tape mode
selector mechanism. The deck can be set to rucording playback,
forward, rewind, stop and pause directly iust With a light push on
the switch. There is also a full autovstop mechanism which stops the
tape when the tape is fully wound, and this safeguards the tape
against damage.

Variety of Accessory Mechanisms
Dolby' noise reduction system:

A newly developed low-distortion IC is used for the Dolby NR
system. This serves to reduce greatly the irritating noise heard when
you play back a tape, and it does this without impairing the sound
quality of the original program source. This helps to increase the
dynamic range, and it allows recordings and play back with agood
signal-to-noise ratio.

Output Level Controls with a Clickrstop Position for Easy
Pinpointing of the Reference Playback Level:

The output (playback level) controls can be used to vary the
output level continuously and they are also coupled to the level
meter. This means that it is possible to check the output level on the
meter, regardless of the strength of the recording level. When the
controls are set to their click-stop position, the reierence playback
level can also be checked.

Unattended recording, wake-up playback functions:

If you use the deck along With the optional timer, you can
record the FM broadcasts you do not want to miss while you are
out, and you can also wake yourself up in the morning with play-
back from a program source instead of being rudcly awakened by an
alarm clock buzzer.

Mic plug-coupled input selection:

When the program source Is connected to the MIC iacks, the line
input terminal signal is automatically switched to the microphone
signal.
