Dynamic type tonearm RS-212D ・ RS-309D
- Cross suspension system:
- Dynamic balance: Unlike the conventional dynamic type tonearms that are prone to an adverse effect of the spiral spring vibration. RS tonearm completely eliminate the external vibration by new spring mechanism housed within the pivot case.
New RS tonearm is able to calibrate from 0 - 5g ideal for heavy cartridge of SPU. - Inside force canceller: Anti-skating tracking force can be calibrated from 0-5g with calibration dial.
- Tonearm height can be adjustable from 42mm to 55mm
- Headshell SH-4is included.
- Digital scale DS-1 is included. The stylus pressure ( 0 - 5g) can be precisely calibrated.

Static type tone arm AS-309S ・ AS-212S
- Cross suspension system: One point support of total moveable tonearm mass front- and- rear, right-and-left one point cross suspension
- Inside force canceller: Inside force caused by rotation of Disc groove to the center of Discs should be cancelled for correct stylus position in a groove. Anti-skating tracking force can be calibrated from 0-5g with calibration dial.
- S curb shaped tonearm: The ideal S curve tonearm offsets to minimize the angle between groove direction and stylus tracking angle.
- Tonearm height can be adjustable from 35mm to 55mm.
