Platter with magnetic bearing Print
Wednesday, 01 February 2012 13:00

Platter is sandwich type made of two 15 mm. aluminium discs with 10 mm. acrylic insert. Thickness 40 mm.,diameter 320 mm., weight 7 kg. Has a conical hole for bearing spindle. On bottom side can be made ring with gaps ( in photos you see platter with 240 gaps ring ) for optic sensor of speed controller or rotation counter. Mat - natural leather.

Radial swinging ≤ 0,05 mm, vertical swinging of platter edge ≤ 0,2 mm.

As platter is not solid, has layers of acoustic different material, it has no resonances.

Bearing is classical type - a 9mm. steel shaft within a steel sleeve. The outer surface of the shaft and inner surface of the sleeve are precisely polished. Tip of shaft rests not on steel or ceramic ball, as usual, but on magnetic pillow, created by two neodymium magnets. This eliminates hard mechanical thrust between the shaft and bottom of bearing and reduces vibrations of platter. As diameter of magnets is only one inch and distance to tonearm is long, this does not affect the cartridge. The assembly is located in a 40mm diameter aluminium housing that is filled with oil. Length of bearing – 90 mm. Flange diameter – 100 mm.

 


 



 

 
Record clamp for high-end turntables Print
Wednesday, 01 February 2012 12:00

Clamp made as a sandwich of two plates of 5 mm brass and one 30 mm granite Matrix Anticato. This stone was formed in gelling of lava, and has laminated structure. It results its specific acoustic features.
There is a internal chamber inside of clamp. It filled with tungsten powder. Weight of clamp depends on quantity of powder and can be from 620 to 1000 g. Powder is material , free of own mechanical resonances, very well damped oscilations of objects to which it comes into contact.
Unit of three acoustically very different materials – metal, stone and powder and construction of clamp make a good damping effect.This effect increased because of shape of clamp.
Influence on the sound of turntable is of course subjective matter, some of audiophiles notice bass improvement, better ataque, bass become tighter, others defined improwed dynamics, smooth mid range and high frequency response, less distortion.
This heavy turntable center weight is suitable for heavy duty turntables with strong platter dryve system.
Diameter:      90mm
Height:          45 mm
Weight:         960 g
