Belt drive type player with DC servo control.

The mechanism section is equipped with a small DC servo motor, and constant speed rotation is obtained by controlling even a slight rotational deviation with the servo mechanism. The belt uses a neoprene belt with excellent material, hardness, and finish accuracy to improve constant speed rotation characteristics.
The turntable is made of die-cast aluminum alloys, and the turntable shaft is made of 12 φ stainless steel. Bearings are made of gunmetal.

In order to maintain stable characteristics of the motor unit, a large housing that is less affected by changes in external temperature is attached.

A current limiting circuit is used in the power supply section to control the temperature of the motor itself even under transient load to the turntable.

The tone arm uses the mechanism of the rotating part of MA-202.
The vertical bearings of this tone arm use a combination of a highly accurate pivot and an original angular type bearing, and the water plain bearing section uses radial bearings at two points above and below, achieving an initial horizontal and vertical sensitivity of 10 mg or less.
In addition, it is equipped with a variable needle pressure inside four scan seller that improves the tracing ability of the cartridge.
The main weight for needle pressure adjustment is a one turn direct reading type between 0 and 3g. The appropriate needle pressure of the cartridge to be used can be obtained by adjusting the horizontal balance of the arm and the needle pressure indicator to 0. A sub weight is attached to the rear part.

The output code uses a low-capacitance type of 50pf/m and is compatible with 4-channel playback.

The arm lifter uses an oil dump type that makes contact and release between the record surface and needle tip smooth.
In addition, there is a queuing guide pin that can easily adjust the height of the arm lifter.

Die-cast H-303 is used for the head shell. In addition, the head lock connector part can be vertically adjusted.

The solid base that supports the mechanism of the player has been adopted after consideration from various aspects such as mass, flatness, and resonance. As a countermeasure against howling, compression homogen with low resonance point is adopted as a material to avoid unnecessary internal space.

The switching mechanism of power ON / OFF, 33 1/3, 45 rotation is an electronic type. Since there is no belt replacement, the influence on belt maintenance and rotation speed characteristics is reduced.

33 Each 1/3 and 45 rotation is equipped with an independent fine adjustment control, and adjustment of ± 6% is possible for the specified speed.
The number of revolutions is checked with a strobe and neon lamp inscribed on the outer circumference of the turntable.

Height-adjustable absorbers and levels allow horizontal adjustment of the player.
