FEATURES
(TURNTABLE SECTION)
@33.CM (13") ULTRA-LARGE DIAMETER TURNTABLE
PLATTER
33 cm (13) ultra-large diameter, and 1.75 kg (3.86 Ib) heavy weight
turntable platter has an inertial moment of 310 kg-cm? (105.9 Ib-in?)
'and has been dynamically balanced.
'Around the turntable platter are strobo marks which are used to
check its speed.
@DIRECT DRIVE MOTOR
There is no "wow" or "flutter caused by transmission mechanism.
There is no vibration because this motor has no high-speed rotation
mechanism, The rumble is extremely low.
@ELECTRONIC COMMUTATOR BRUSHLESS DC MOTOR
The DC motor is not affected by fluctuations of the power supply
frequency. Starting rotation power is large, with complete stability of
speed reached within one-half rotation at 33-1/3 r.p.m. since there is
'no electro-magnetic hum, the signal to noise ratio (rumble) is excellent.
'And, because the motor includes an electronic commutator, starting
is perfectly accurate. There is, therefore, no speed instability or brush
deterioration as is often noted in brush commutators, no pulse noise
generated by brush sparking and no sound caused by rubbing of brushes.
@ROTATION OF THE TURNTABLE PLATTER CAN
BE STOPPED AT ANY TIME
This is a feature which is not found in players which have speed
reduction and transmissions devices such as a belt or idler.
If such stopping is attempted on ordinary players, the belt or idler will
soon deteriorate and efficiency soon becomes poor.
In this player
system, such stopping causes no problem other than a slight increase
of the motor current, which is not really a problem.
@ELECTRONIC STABILIZATION CONTROL
Because this set includes special circuitry to stabilize the speed electri-
cally, speed stability is extremely good.
@ELECTRICAL SPEED CHANGE
There is no mechanism to change the position of the belt or idler
There is, therefore, no "wow" or unwanted speed change.
@NO EFFECT FROM FLUCTUATIONS OF POWER
SUPPLY FREQUENCY OR VOLTAGE
Since the motor is the DC type, the rotation speed does not depend
on the power supply frequency. And, because a OC-stabilizer is used,
the set is not wffected by changes of the power supply voltage, even if
the fluctuation is large.
@SEMI-PERMANENT HIGH PERFORMANCE
Unlike previous players, there is no reduction or transmission mecha
nism, such as a belt or idler.
'The motor rotates the turntable platter directly at an ultra-low speed.
Wear of parts is therefore reduced to the extreme minimum and high-
performance efficiency can be maintained semi-permanently,
(TONEARM SECTION)
@EASY BALANCING AND STYLUS PRESSURE
CONTROL
By a smooth rack-and-pinion type movement, the balance weight can
be adjusted easily. After adjusting the zero balance, pull the outside
of the stulys pressure knob outward, and the scale will be reset auto-
matically to the zero position. Now you can add the amount of stylus
Pressure you desire by directly reading the scale.
@FEATHER-TOUCH CUEING
Feather-touch cueing is viscousdamped in both directions for gentle
decent and ascent. The tonearm willbe set down exactly on the spot
you desire.
