Target set to the highest analogue sound quality,
consumed the longest development period.
Base unit is made of 6 types of materials, selected after long time of auditions. They are aluminium, stainless steel, brass, gunmetal, copper and acrylic.
The platter is designed with in a tapered shape. Tuning screws are made by copper to overcome "bell vibration". In addition, a piece of glass mat is added on top massive aluminum material to soften metallic sound.
An oversize bearing is used in GINGA.
Center pole is φ25, super hard bearing are used to support the large-sized spindle rotor. Moreover, operation of the platter become more stable with raising height.
The center pole and the spindle rotor are 1 set. High precision alignment process is applied.
Contacts between ball bearing is filled with the special oil for durable and stable operation.
Large 4 pole synchronous motor is used for best sound quality. Low-noise and low vibration are achieved by double-floating structure.
Motor is driven by an ideal power supply. CR oscillating circuit is composed of SIN, COS wave generators with dual channels high power low distortion amplifier. Therefore, phase advance capacitor became unnecessary. Moreover, voltage control of the main coil and subcoil are fully independent making oscillation to be minimal.
By using tension pulley, long time and stable operation are possible with adequate string tension.
The knot of a string is the most popular and traditional problem of a thread drive system.
In GINGA, we use a knotless cotton string to realize smooth and vibration-free rotation. The curvature of a disk can be rectified by using a spacer ring and a stabilizer. (effect may various for a heavy weight class disk or the disk with severe curvature.)
