Direct Drive
Quartz-lock Fully Automatic Turntable
Model
ST-540's direct drive and fully automatic operation provide perfection and
highest quality. Quartz-lock insures
that the turntable rotation will not vary under changing load or
voltage. Rotation precision is maintained at ±0,0001% and rumble has been
almost eliminated. Wow and flutter have been reduced to negligible levels by
improvements in the direct drive.
The Low
mass, straight tonearm, is statically balanced for improved tracability, has a
removable headshell and antiskating device. The optional moving magnet (MM)
cartridge with diamond stylus assures faithful reproduction for the utmost in
listening pleasure.
Acoustic
feedback reduced.
Improvements
made in the subchassis have greatly reduced acoustic feedback. The independent
suspension of the floating chassis improves howling performance and pushing the
operation buttons does not move the chassis. The hefty, solid base stands
firmly in place when the operation buttons are pushed.
All-front
operation.
All
operations are by feather-touch buttons located on the panel. Even cueing can
be performed with the dust cover closed. Operational simplicity is combined
into this convenient arrangement.
Fully
Automatic operation
Simply place
your favorite record on the platter, close the dust cover and push the button.
That is all it takes for this fully automatic turntable. Lead-in is automatic
and the tonearm will return to rest and turn off power when the record ends.
Oil-damped
cueing.
The delicate
stylus needle is gently lowered into the record groove with oil-damped cueing.
Thus you are now assured of safer and easier record play with no impact shock
when the needle contacts the record.
