About the Turntable
ONE DEGREE OF FREEDOM TURNTABLE
Please write for details
ONEDOF™ is a fundamentally reinvented turntable designed by NASA-award winning aerospace engineer Aleks Bakman.
The turntable features:
· The first in turntable history self-centering in all directions non-resonant (due to non-linear stiffness and damping ratio) platter bearing based on smart fluid technology.
· The innovative bearing removes platter spindle instability, eliminating a never before addressed cause of acoustic distortion.
· Noiseless, noise canceling drive.
· Damped and automatically centered record clamping ring for the highest in the industry allowable volume of music reproduction without distortions.
· Tonearm tower with continuous, smooth yet solid on-the-fly Vertical Tracking Angle adjustment over three inches.
· 60 lb metallic platter spindle with internal liquid damping. The turntable weights 110 lb.
· 24 carat gold plating.
THE ONEDOF STORY: Idea of a perfect, zero tolerance self-centering non-resonant friction free bearing came to Mr. Bakman in 2000, when he was skiing down the 14265 ft. (4350m) Quandary Peak in Colorado. Research, calculations, and design of the bearing took evenings and weekends of more than five years. Aleks's day job at that time was developing spacecraft for Lockheed Martin Space Systems. Finally the first manufactured bearing had shown better than expected performance. The trouble was that the science did not stand still all those years. Redesigning bearing based on the latest NASA publications took another year, but the bearing had become orders of magnitude better. It was the turn of an electric motor drive to be optimized beyond recognition. After that being done in just a couple of years, came the epic battle of ever more damping.
Any metallic platter rings like the bells of St. Paul’s Cathedral. Inside the Onedof platter hollows Mr. Bakman placed high tech witch’s brew of proprietary particles in an undisclosed liquid. Already viscous liquid becomes infinitely more damping due to enormous surface of the microscopic solids suspended in it. The platter had lost its tongue and became mute. The sound stage had mushroomed with the deeper shade of black on the background.
Now you know how to build your own Onedof Turntable. You start by climbing the peak.
- Microscopic whirling in the conventional platter bearing leads to macroscopic wobbling of the platter. This design problem of all bearings is solved. It is eliminated by the innovative design of self-centering in all directions Onedof™ platter bearing.
ONEDOF means "one degree of freedom of motion" - only steady rotation.
- The suspension and the bearing are maintenance free.
- There is no friction, no wear, virtually no heat generated, no thickening or pollution of the oil.
- This bearing will last many generations without service.
Suspension and Damping
Another first in the history of turntables is a resonance free suspension.
- Suspension is an integral part of the Onedof™ bearing.
- The viscous uncompressible liquid, locked in the sealed volume, suspends heavy rotating mass.
Pressure is generated by the rotation of the platter. No pumps.
- There is no solid load path from the platter to the stand.
- The suspension blocks the distortions coming from the environment.
- The suspension cancels the vibration of the platter/spindle assembly.
- The suspension does not generate its own distortions.
- The viscous oil provides non-linear damping in all directions, there is no condition for the resonance.
- Large sealed chambers inside the platter are filled with a mix of viscous oil and solid particles to damp out the resonances of the platter.
- Around the perimeter of the platter the precious vinyl record is pressed down by a massive damped and automatically centered clamping ring.
The Tonearm Tower
- The tonearm tower, featuring continuous and smooth on-the-fly VTA adjustment over 3 in., works with any tonearm and cartridge combination. Tonearm has massive support, to prevent resonances. The Onedof ™ turntable can work with four tonearms simultaneously.
