This
hi-fi record player is equipped with "Direct Control", a completely
new type of drive system combininig the advantages of both belt and direct
drive systems and ensuring an absolutely constant turntable speed with
negligible wow and flutter.
The prime
mover is a d.c. motor which drives the turntable/tachometer assembly via a
precision ground belt. The tachometer continuously monitors the turntable
speed, which it feeds to an electronic circuit. This compares the signal from
the tachometer to an extremely stable reference signal. Should any difference
be found, a control signal is immediately triggered, the action of which is to
adjust the power supply to the motor so that the correct turntable speed is
instantly obtained. Mains voltage or temperature fluctuations and varying
frictional forces arising from, say, the use of a cleaning arm thus have
minimal effect on the turntable speed.
Other
features of this record player in addition to its unique drive system are:
Extremely
low rumble, thanks to the independent suspension of the turntable and pick-up
arm.
Electronic
touch controls for starting and stoping. These are a great convenience and are
silent and vibration free in operation.
Function
indication by LED's
Precise
adjustment of turntable speed is made possible with the aid of fine-adjustment
controls and an electronic speed indicator.
Adjustable
stylus force and side-thrust compensation
Viscosity
damped pick-up arm lift
