Commentary
A full-auto player with a compact body of 31.5 cm in width and depth, equipped with a program function of 10 songs.
The upper cabinet is equipped with a linear tracking arm, and the needle tip moves linearly on the record board, so tracking error and inside force, which cause distortion, are kept to a low value.
The linear tracking arm uses a unique dynamic balance system, and the center of gravity is aligned with the center of rotation axis, eliminating the need for precise horizontal adjustment.
The arm bearing structure adopts a 4-point support gimbal suspension with a pivot and ball bearing to obtain high initial motion sensitivity.
The cartridge uses P205Cmk3 with a pure boron pipe cantilever. Combined with the unique bridge yoke structure, it realizes an extremely small transducer effective mass of 0.149 mg.
In addition, a precision mirror-polished HPF core is used for the magnetic circuit, enabling wide-band reproduction by improving the performance of the vibration system and power generation system.
A plug-in connector system is used to connect the cartridge and arm and no lead wire is required. This prevents poor contact between the cartridge terminal and the arm terminal due to lead wire connection, misconnection, and partial resonance at the joint.
Electronic control full auto mechanism allows easy operation with 4 keys after the record is set.
Equipped with program keys from 1 to 10, up to 10 songs can be automatically selected according to the order in which the program keys are set.
The music sequence proceeds in the order in which the program keys are pressed. When programming, the LED next to each key lights up and confirmation is possible.
Separately sold player stand can be used.
