Commentary
Quartz DD turntable adopting 3-layer structure solid base by thoroughly pursuing non-resonance.
It uses a solid base with a three layer structure sandwiched between 8 mm thick pure aluminum and 15 mm thick high-density glass with high plane accuracy and weight of 7.5 kg, eliminating vibration transmission and resonance.
The turntable seat is also made of 5 mm thick hard glass, adhering to the concept of non-resonance, and together with the heavy weight aluminum die-cast turntable, it is designed to resist unwanted vibration.
The Phono Motor drives a turntable with a gross weight of 3.4 kg. It uses an all-quartz lock DD motor with a high starting torque of 1.6 kg.
It achieves start-up characteristics that reach normal rotation at 1/2 rotation after start, and achieves high-precision rotation that is stable against additional variations.
The arm base uses a solid type of machined aluminum block to eliminate the influence of unnecessary vibration and draw out the tracing ability of the arm.
This arm base is a universal type capable of mounting a tone arm with an effective length (the value obtained by subtracting the overhang value from the effective length of the tone arm) of 190 mm to 230 mm.
Uses touch sensor type operation buttons.
The sub-arm space provided at the left back of the base allows upgrading to double-arm type.
A large air-suspension type insulator is used for the insulator.
Height adjustment is possible, and accurate setting of turntable horizontal reference is possible.
The power supply section has an independent structure to reduce hum noise caused by electromagnetic induction.
To stop the turntable, we have adopted a structure in which an electronic brake is linked to the stop button to improve operability.
Equipped with LED indicator to indicate constant speed rotation.
Arm and cartridge are not included.
