FEATURES

Linear tracking tonearm

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).

Front panel operation with the dust cover closed

The ARM TRANSPORT buttons allow you to move the tonearm easi-
ly over the desired point of the record with the dust caver closed.
Startlstop oi the record play and tonearm upidown can also be con-
trolled using the buttons on the lront panel.

Fully automatic system

The movement of the turntable and the tonearm is controlled by a
microcomputer and is activated by the "leather-touch" function
buttons on the tront panel.

Automatic record size selection

The record size is automatically set by a photo sensor system. it 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 after 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 servo system
The turntable maintains an accurate and drill-tree speed by refer-
ring to a frequency generated by a very stable quartz oscillator.

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 flutter. Its high torque
assures a quick start to 33 'h 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. This synchronized operation is possible with Sony
cassette decks equipped with a tour-pin remote control jack which
is connected with the Sony FtM-65 synchro remote control unit.
