Ideal sound pickup

Records have 120-micron-wide sound grooves engraved at least 600, with small signal intervals and large signal intervals and irregularities, so it is important to trace sound grooves stably from the outer to the inner circumference.

• Do not cause microtremors when the cartridge traces.

• Lightly and smoothly move to the adjacent sound groove

• Vibration generated by the needle is transmitted only to the power coil without being subjected to unwanted vibration.

The ideal sound pickup is:

In addition, since the cutting lace moves in a straight line to engrave the sound groove in the manufacturing process of the record, the tracking error of the outer and inner circumferences is eliminated.

• Move in the same trajectory as when cutting even during tracing
  It is also ideal.

AFU1-2 pick-up philosophy

• Weight of 1.0kg suppresses microtremors and traces sound grooves accurately

• Air float moves lightly and smoothly with a force of 0. 5g or less

• Absorbs unwanted vibration and external noise with an air film of 0.01mm

• Trace in a straight line with the same trajectory as the cutting machine

​

The AFU1-2 was developed under the philosophy of picking up sounds.

AFU1-2's proprietary airfloat design allows the arm to move without applying servos with a force of 0.0 5g or less, and leaves the servos to the sound grooves. The irregular record groove is traced from the outer circumference to the inner circumference without missing the minute movement of the needle tip while suppressing the generation of noise.
