Silent Synchrotor System

Desptte the tremendous tmprovements that
the directrdrtve turntable has brought to
hl'li. many "golden eared' audtoohtles have
noted that they sound distant luzzy and
unfocused We have proven that there ts a
grain of truth to thts contplatnt

In most dtrectrdrtve turntables the
motor lS located near the center of the cabtr
net When the motor rotates the platter
clockwtse, tt appltes a torque to the cabinet
tn the same dtrectton To compensate and
restore balance, the cabinet attempts to
Create counterclockwse torque This leads
to a sertous problem

All difGClOthe motors cog that is
they imperceptrbly speed up and slow down
tn a terky manner as the servo system trtes
to compensate for wow and flutter and other
speed trregulartztes. These mtnute speed
vartattons cause matchtng vartattons tn
motor torque. wntch tn turn setup vartattons

tn countertorque generated tn the cabinet
(th, 1A), These vartattons are turned tnto
actual phyStcal vtbrattons that eventually
ttnd their way to the stylus lt ts these vtbra-
tions that cause sound to be luzzy and
unfocused. because they change the delt-
cate geometrtc reiationshtp between the
record groove and stylus.

The Sansut Silent Synchrotor System
has leiled thts shortcomtng oi dtrect-drtve
turntables in a Stngle blow. As you see tn
th 3A a second motor ts mounted dtrectly
below the man drtve motor and shares the
same axts, Controlled by the same servo
system as the math motor tt rotates tn the
opposite atrectton, creating torque which
exactly ottsets the countertorque created tn
the cabtnet (Fig. 18),

L'sten to the XP-99 you'll hear wetl-
