FEATURES
Tough and
Reliable Construction
The tape deck's construction combines a Smm-thick front
panel and a diecast frame for the outer casing to protect the
heavy inside parts. The construction
is
des;fgned
to display
the maximum precision and durability, and the front
panel
can be mounted in a
rack
conforming to EIA standards.
Tape Transport has D.O. Motor to Drive Capstan
The tape deck's
AC
servomotor with frequency
semnatttr
features direct
capstari drive. Even
the
slightest fluctuations
in
the
speed
caused
by external factors are controlled by
the servoamplifrer.
So
the
motor
displays excellent
load bearing characteristics, and can also withstand
fluctuations in voltage.
Finally, the D.0, system reduces
wow/flutter
and yields a speed subject to minimal
ageing.
For the reel drive, the tape deck uses a pair of 6-pole inner
rotor induction motors with
optimum torque characteris-
tics.
Their low moment of inertia and the use of solenoid-
activated differential
band brakes prevent undue tape strain
and
protect the tape.
4-
Track,
2-Channel, 3-Head Configuration
The playback head with
its excellent in-line characteristics
combines with its
hyperbolic shape (featuring perfect tape
conuct) to improve
the phase characteristics the
frequency response and reduce
crosstalk. Furdiermore,
the recording head's superb bias, S/N
and frequency
response assure very accurate recordings. If the
playback
head is
operating while ihe tape deck is
recording, you can
actually monitor the recording.
All in all, this 34iead
configuration
gives a rellaUe and versatile performance.
Switching Mechanism with Electronic
Circuitry
The tape deck is
equipped with an electronic switch which
employs
FETs and other
semiconductors in the playback
and
recording equalizer
circuits. The recording bias circuit
contains a timing relay,
and induction
noise
as
well
as click
noise generated when this switch is selected are kept to
the
absolute
minimum.
Independent
Recording Amplifier Circuit for LINE
and MIC
Inputs
The recording amplifier
features a high
S/N,
and the micro-
phone
amplifier displays
an
input
sensitivity
high enough
for use with 600-ohm profassionai
microphones.
The
dynamic range
Is an amazing SSdB.
Powered by j regulated
power
supply
and unaflected by
fluctuations
in the voltage
or by changes
in die temperature,
this circuit ensures
stable
recordings at all tknes. In addition, there are
ind^)endent
LINE and
MfC
recording Tevel
controls to enable
you to
have fun with mixing recording,
PITCH CONTROL
knob:
This control Is
used to change the
rated tape speed
during
playback (I9cm/S|
9,Scm/s)
across
a
±6% range
-
in other words, the upe can be made to
go
696 Aster or
slower.
Musical steps can be raised or lowered
as
far
as the semi-
tones. This means
that you
can bring the steps of the
recorded music into line with the steps of the instrument
which
you are playing. This
control is therefore useful
when you
are
using
a tape for song accompaniments.
