MICRO MR-322

Commentary

A belt drive player with the highest class tone arm.

An aluminum die cast turntable is used as the turntable, and the drive system is a belt drive system using a four pole outer rotor type motor with a die cast radiator.
The die-cast radiator improves heat radiation and reduces motor vibration, resulting in improved durability.

The power switch is built into the arm rest and is interlocked with the belt lock mechanism which is highly effective for belt maintenance.

Fixed bearing is used for the rotating part of the tone arm, and special alloy pipe and high composite die cast shell are adopted.
In addition, it is equipped with Micro's own spring tension type inside four scan cellar to enhance tracing ability.

Uses MM type cartridge M-2100/6.

An oil dump type arm lifter is adopted.

It uses a newly designed insulator with adjustable height.
