Kenwood KD-2055 turntable

The model KD-2055 is carefully designed and manufactured to obtain the basic characteristics that must be completaly assured by the turntable. The turntable  is constructed mainly of turntable cabinet dust cover, turntable platter, tonearm with cardridge and driving motor. Performance of each part used in KD-2055 is very important.

 

The turntable cabinet is an one of essential part for accommodating driving motor, platter, tonearm, etc., which are directly concerned with record reproduction. The most significant matter for high fidelity reprodction is to insulate the cartridge, record, record, tonearm, etc., against harmful internal and external vobrations such as vibration of the driving motor and acoustic feedback from the speaker system.

Meaning of vibration-proof property;

Periodic damping rate is high - periodic damping time is short.

Periodic damping pattern shows a smooth feature without turbulence (if any, shows that there is energy loss due to resonance)

The cabinet of KD-2055 emplys a layer construction of A.R.C.B (Anti Resonance Compression Base) so to speak resin concrete and plywood.

A.R.C.B. is a compressed and formed material, which is mixed with stone grains of 1-5 mm in diameter, calcium carbonate powder, glass powder, and polyester resin. This material is rich in processing accuracy, strength and esthetic value.
