Simple, Rugged
Structure

The vacuum disc stabilizer is the
sysmm to integrate the record disc
and turntable platter by means of
removal of air between them. To
pick up all pieces of music informa-
tion contained in the grooves of
disc and further to eliminate un-
necessary influences caused by
resonance, etc. are the basic condi-
tion required for turntable. For this
purpose such accessories as so-
called audio stabilizer and special
platter mat have been used and
specifically improved among
audiophiles. But conventional

stabilizers have had such problems
as to depress not the entire sonic
grooves but a part of the disc and
give bad effects to the turning servo
mechanism due to variation of
weight.

The vacuum disc stabilizer is, in a
sense, an audio stabilizer by means
of atmospheric pressure, which
works evenly throughout an entire
surface of the disc without adding
weight on the platter. This is truly
an ideal turntable system.

The structure is very simple; to suck
out the air, the groove and sucking
hole are provided on the surface of
the platter and the air passage goes
thru the inside, which is connected
to the external stabilizer unit.

Highly Airtight
Construction

The record disc perfeCtly sticks to
the platter, which can be sustained
long. When the stabilizer is turned
on, the atmospheric pressure fixes a
disc firmly to the platter. In terms
of weight, this means a stabilizer of
250kg is imposed on the disc, and
the disc and platter are almost
perfectly unified, thus providing an
effect that the platter itself were
changed into the disc. This banishes
flawlessly all harmful bass noises
(S-lOHz) by resonance of the disc
itself or that of the tonearm and
cartridge caused by the warp of
disc. .

After the stabilizer sucked a disc to
the platter, the airtightness is main-
tained for long time, as the air
passage is kept airtight by means of
the sealing pad (Pat. Pend.), sealing
ring, silicon liquid packing, etc.

Once the disc is fixed, the external
stabilizer unit stops function and
provides no noise while playing the
disc. To create almost vacuum
space, a vacuum pttmp is used as a
stabilizer unit. Unlike conventional
ones, high dependability and tran-
quility are simultaneously ensured
with high-precision, robust struc-
ture. The stabilizer unit provides
almost inaudible noises at the time
of sucking and its release. Once the
disc is fixed it ceases to operate and
no noise or vibration is caused
while the disc is played.

The stabilizer unit is operated by a
feather-touch switch on the turn-
table, and its connCCtion can be
done easily by the remote cable and
sucking tube. 2-meter length pro-
vided to the cable and tube allows
you to place the stabilizer ttnit
wherever you want.
