The PD300 is the first turntable incorporating the disc suck-

UUM I ing system, where a vacuum pump of simple robust con-

struction is employed with application of the theory of

bellows. To suck out the air, grooves and sucking hole are

s IABILI 2 ER provided on the surface of the platter, and the air passage in-
side the platter is connected to the pump by means of tube.

The pressure given to the sound grooves is equivalent to
placement of 30kg stabilizer in terms of weight, and perfect

Suction and its release can be done by simple one-touch
operation of the suction lever provided at the front of the
cabinet, thus ensuring easy accessibility. Normally the lever is
placed horizontally, and when it is turned upright, sucking
function is activated. When the specified level of suction is

The playback method 0f record disc has been unchanged vacuum state by keeping sucking, which inevitably causes
for all ages-Simply to put a disc on the platter and then to

place a pick-up on the disc. But this simple operation com-
prises various problems. Among others, what cannot be
neglected in terms of sonic quality is self-resonance of the
record disc. Such harmful additives not contained in the
original signals have to be removed by all means for purest
fidelity reproduction.

So far, many audiophiles have tried to make improvements
in this respect utilizing so-called audio stabilizer of special
platter mat. But no definite solution has been given to the
problem of this noxious modulation triggered by a slight warp
or resonance of the disc itself.

The V.D.S. system is to integrate the record disc and turn-
table platter, so to say, to make a record disc of high inertia.
By removal of the air between the disc and platter, at-
mospheric pressure changes itself into a stabilizer, which
works evenly throughtout an entire surface of the disc. This is
truly an ideal turntable system.
