FEATURES

Linear tracking tonearm

A linear tracking tonearm is designed to duplicate the movement ol
the head which cuts the record master.

Compared with a pivoted tonearm. a linear tracking arm has a very
small tracking error (which means greatly reduced harmonic distor-
tion) and almost no pressure on the inside wall of the groove (which
means improved tracking ability and channel separation).

Biotracer electronic tonearm

The horizontal and vertical movement of the tonearm is monitored
by the Biotracer's own sensors. and this inlormation is transmitted
to the tonearm by the tonearms own linear motors to suppress
resonance at low frequencies and to obtain the maxrrnum signal-to-
noise ratio. With the microcomputer incorporated, the tonearm
movement, upldown or forward/backward. is accurate and smooth.

Front panel operation with the dust cover closed

The AFlM TRANSPORT buttons allow you to move the tonearm easi-
ly over the desired point of the record with the dust cover closed.
Start/stop oi the record play and tonearm up/down can also be con»
trolled using the buttons on the lront panel.

Electronic stylus lorce adjustment
As the stylus force is adjusted by the control on the front panel and
digitally read out. it can be easily adiusted even during record playt

Automatic record size selection

The record size is automatically set by a photo sensor system If no
record is on the turntable. the tonearm will not descend but will
automatically return to the arm rest,

Muting system

A muting system activates when the tonearm is lifted and is deac-
tivated alter the tonearm lowers onto a record so there is no need
to turn the amplifier volume down every time a stylus is placed on a
record.

Quartz lock and magnedisc servo system

The turntable maintains an accurate and drift-tree speed by refer-
ring to a frequency generated by a very stable quartz oscillator. and
with aid of a speed monitoring system which utilizes a magnetic
pick-up head and a pulse Signal derived from a magnetic coating at
the edge of the platter.

Linear torque BSL motor

Direct drive system with Sony's unique BSL (brushless and
slotless) motor which has an extremely low noise level and whose
smoothness virtually eliminates wow and tlutter. its high torque
assures a quick start to 33 I1 rpm after only a halt revolution.

Synchronized operation with the Sony cassette decks

When the tonearm lowers onto the lead-in groove of a record. the
cassette deck stand-by mode is released and the record mode
assumed. When play finishes, the cassette deck is automatically
set first in the record muting mode. then in the pause mode. This
synchronized operation is possible with Sony cassette decks
equipped with a tour-pin remote control jack which is connected
with the Sony RM-65 synchro remote control unit.
