Commentary
UA series universal tone arm with new gimbal support system.
A virtual one point support structure is adopted for the bearing system, and strength and reliability superior to gimbal support are pursued.
In the virtual one point support structure, four precision radial ball bearings are arranged long distance from the virtual center point, so the force applied to each bearing and the rotation angle are equal for any rotation direction, and the same performance as the one point support can be obtained.
In addition, all bearings are fixed to the same part by micron precision machining using camera technology, ensuring high sensitivity and high durability.
A chucking lock type head connector is adopted, and looseness is eliminated by strongly tightening the shell plug part with the same principle as the drill chuck.
Uses a non-resonant head shell in which the shell body and plug part are integrally molded.
