MICRO SEIKI DQX-1000
Design Integrity -
These unique design
concepts have been exhaustively researched and tested by our engineers. All the
manufacturing and assembly stages conform to the highest quality standards in
order to produce this definitive turntable system. The result is surely one of
the finest turntables available. Absolutely superb mechanical stability and
precision.
The Ideal Comprator
-
Itself incomparable,
the DQX-1000 can help you enormously in comparing cartridges and tonearms. The
turntable is so neutral, you effectively remove it as a variable in your
judgment. And since up to three arms can be mounted simultaneously, your
comparative evaluations will be much more accurate and definitive.
The Unique Turntable
System -
The three large
insulators on the DQX-1000 form a unique absorber mechanism taht not only
eliminates entirely the hazards of external vibration, but also serves to
isolate the arm mount from the turntable. Up to three high quality tonearms may
be mounted simultaneously, and tonearms are interchanged easily and quickly.
The power supply and transformer are completely isolated in a separate control
unit, thus eliminating any feedback or hum interference.
Turntable
The
exceptional performance stability of the DQX-1000 can be attributed to the
large: 31 cm; 2,9 kg, the platter has a significantly high moment of inertia:
600kg/cm². Additionally, a low shaft burden has been
achieved by distributing the weight around the perifery of the platter. The
rotational momentum is accordingly very even and constant. Sroboscope markings
are inscribed on the turntable, and as the stroboscope is aligned to a
buuilt-in oscillator, power line variations have no effect whatsoever on the
rotational speed.
PLL Quartz locked Servo Motor
The DQX-1000 uses a
direct drive, frequency governed servo
motor for optimum speed stability. A strong 1,5 kg (3,3 lbs) starting torque
facilitates fast, accurate speed attainment. And even under extreme conditions,
the constant speed characteristics are unsurpassed: a 3 gram stylus pressure at
30 cm from the center of the platter produces non speed deviation
Turntable Frame
A unique 3-point
supporting frame has been developed in order to increase the stability of the
DQX-1000 system. Thus the mechanism is contained within the most stable
operating conditions possible. The 1,9 kg frame is made of aluminium alloy.
Motor Shaft
Reinforcement
The motor frame
features a structure which is integrayed with the unique 3-point supporting
frame. The resonance which is generated as the platter rotates is improved with
the resulting mechanical strength. A reinforcement effect is also provided for
the motor shaft (platter shaft) since it serves as a supporting pillar. This is
a structure which clearly defines the fulcrum of the platter when the records
are being played.
Insulators
The two-layer
absorber system consists of cushion rubber and fulcrum lies in the upper part
of the insulators, the resulting low center of gravity both horizontally and
vertically.
Arm Mounts
Six modular arm
mounts are available optionally for precise, convenient installation of any
high quality tonearm on any of the three positions. Now you can easily compare
performance characteristics of tonearms and cartridges in order to maximize the
efficiency of your total system interface. The DQX-1000 allows you to match
specific disc playback characteristics with your cartridges and loudspeakers
for the fullest possible enjoyment.
Control Unit
The turntable
controls and power supply have been incorporated in an independent unit for
optimum ease of access to the power button, speed select buttons, and fine
speed adjustment controls, which can very the rated speed ±6% - a full octave.
Magnetic materials
are excluded from the cover, and a wooden case is employed in order to improve
the sound quality. The quartz circuit has an On/Off control, and when it is set
to Off, the signals bypass the PLL servo circuit entirely.
