FINEST ANALOG DEVICES
Chassis:
The chassis of the drive is made from a special ICI material to ensure
virtually no resonance. This is about a casted material, which has
extremely good internal damping features, because of the added extras.
We also use 3 LRP elements (Low Resilience Polymer) in our
sub-chassis-construction, which decouples the plant level from the base
on the one hand, and fights oscillation in the material on the other
hand. The LRP elements are arranged in the chassis corners and around
the platter bearing. When you compare these to metal spring
constructions, there are no longer obnoxious material resonances of the
spring or phenomenon’s of sway. The Base is connected to the table with
three metal spikes. The setting up is uncomplicated and quick, because
you only have to care about the horizontal adjustment; no additional
adjustment necessary, like for example spring elements etc.

Platter:
The platter weights 5kg and is made from casted metacrylat. Its
characteristics are very similar to the vinyl. During a very complex,
temperature optimized process the platter gets drilled to its exact
dimensions and afterwards follows the quenching and tempering of the
surface. This process prevents stress in the material, which would
affect the acoustic qualities. By using the plane platter profile we
reach a big matching between vinyl and platter. Furthermore, resonance
diffuser in the inner area of the platter eliminates the well known
material resonances in massive plastics platter in the area between 9
kHz and 13 kHz.
Bearing:
The rotation-center of the platter is
a ceramic ball in the middle of the inversed bearing. Both, bearing bush
and vertical axis are made from multiple hardened steel. Accurate
selection and very little tolerance guarantee a perfect, noiseless
operation and long lifetime. All moving parts are supplied with a very
thin but very good greasing special oil from a oil reservoir at the
bearing base. Due to the massive body and the special geometry of the
bearing, our platter bearing doesn’t tend to oscillate like most of the
other. That is proven by objective measurements we made with the pulse
measuring process. Pulses at different areas on the platter are dying
out consistent and without excessiveness. An important advantage of
inverted bearings is their high fulcrum, which minimizes tilting and
commuting.

Motor unit:
The core of the drive is a DC motor with LSC (Linear Speed
Controller), which runs without jerk, mounted mechanically isolated in
the drive chassis. An outsourced switching power supply is used for the
demand on power, which could produce 50 times more current than needed.
A very thin string made from a duplex material carries the power from
the pulley to the platter. You can switch electronically between 33 rpm
and 45 rpm. In addition, you can fine tune each speed separately.
Therefore we use padder with a gearbox 1:25.
