Rotating
Assembly
The massive
platter sits atop an incredibly thick, 16 mm main shaft. Its concentricity is
machined to within 0,4 microns. The bearing material is a special alloy
lubricated by and suspended in a unique oil-bath damping system. Not only does
the system negate the need for periodic user lubrication, it is unaffected by
temperature changes and aging.
Drive System
The
brushless, servo-controlled motor is of the outer-rotor design and uses
sophisticated electronic circuitry to maintain speed acciracy. The
specially-engineered, low-tension drive belt is , made of a carbon/urethane
compound for maximum longevity and is pround to a precise thickness of 0,45 mm.
Motor speed is user variable.
Genuine Wood
base
One of the
best acoustical damping materials know is wood. It is used as the base material
for all Micro Seiki turntables and BL-51 is natural ebony finishes.
The model
BL-51 can accommodate the following tonearms:
