Description
 
It is the electronic-control full auto player which supplied the technology cultivated with the high-end model, and was developed.

The record size automatic detection mechanism in which the optical system was applied is adopted as detection of record size.
By this system, light is glared from the slanting upper part with a reflector, light is led to a sensor from the reflector for turntable sheets, and the output of a sensor is changed by glaring / covering light according to the size of a record. This output is sent to a logic circuit and record size is detected automatically. Based on the size of the record detected here, a needle descent position and a rotating speed are determined automatically.

The quick response mechanism is carried, and if an arm directs the next operation with a button also in /descent during a rise by auto operation, it will shift to the operation immediately.

The feather touch type which uses a microswitch is adopted as a manual operation button.

EC (electronic control) circuit is adopted as a full auto mechanism. In order to control complicated operation correctly, LSI of one chip is adopted as this circuit.

The needle point protection function is carried, and when there is no record in a turntable, a tone arm does not descend.

The muting mechanism which cuts a noise is adopted.

The anti Resonance filter which added a weight case, butyl rubber, and a damper to the structure by the needle pressure knob and main weight of a tone arm part is adopted, and the vibration is reduced.
Moreover, the instability of the pipe part was abolished by extending the span of a pivot, and perpendicularity and a horizontal direction have realized high sensitivity.

The exclusive motor which became independent in the two horizontal/vertical directions is adopted as the drive motor of a tone arm.

Stainless steel is adopted as the quality of the material of a tone arm.

The DC servo motor is adopted as the drive motor of a turntable.

Wooden cabinets are adopted as a cabinet.

The dust cover was sold as the option.
