Commentary
A direct drive linear tracking full auto player with enhanced operability based on excellent basic performance.
Equipped with a linear tracking arm that moves linearly in the upper cabinet, the tracking error angle is within ± 0.1 ° and the inside force is close to 0 by the optical sensor deflection angle detection mechanism near the tip of the needle, achieving high running performance.
A DC motor with high rotational accuracy and good servo response performance is mounted for arm travel. A slide bearing with low friction coefficient is adopted for the arm travel path to realize high-precision arm travel without unnecessary vibration.
The arm support structure is a 4-point support gimbal suspension bearing structure and adopts a unique dynamic balance system to obtain stable balance performance.
The cabinet uses TNRC, which has excellent vibration isolation and absorption and vibration isolation measures are thoroughly taken.
Excellent rotational performance structure D. D. motor, which integrates the motor rotor and turntable, has been adopted to achieve excellent performance.
The cartridge and tone arm are connected using a unique plug-in connector method.
It eliminates poor contact and misconnection between the cartridge terminal and the arm terminal due to lead wire connection, and reduces performance degradation because the terminal is not exposed to the outside, improving the reliability of the joint.
It is an electronically controlled full auto player that automatically controls the performance of the record with a microcomputer.
Because the player automatically detects the record size, simply placing the record on the turntable automatically sets it to 33 1/3rpm for an LP disc or 45 rpm for a single (EP) record.
The number of revolutions can also be set manually.
Equipped with a 2-speed search function that is convenient for cue during a record performance.
