Setup context
Use this tonearm reference with the Tonearm Match Lab and Tonearm Geometry Lab to plan cartridge matching and alignment. The key setup inputs are effective mass and effective length.
Reference data is best-effort and should be checked against manufacturer documentation before critical setup decisions.

Model-specific cartridge matching scenarios
Its stored effective mass is 11.5 g, which places the arm in the medium-mass range for matching work. The 237 mm effective length is relevant to alignment geometry and mounting-distance decisions. The database records a integrated headshell interface. Stored cartridge-weight support is 4–11 g.
| Reference cartridge case | Cartridge mass / compliance | Estimated total mass | Calculated resonance |
|---|---|---|---|
| Low-compliance MC example | 8.5 g / 8 CU | 20.5 g | 12.43 Hz — above the usual 8–12 Hz setup window |
| Medium-compliance example | 7 g / 15 CU | 19 g | 9.43 Hz — inside the usual 8–12 Hz setup window |
| High-compliance MM example | 6.5 g / 25 CU | 18.5 g | 7.4 Hz — below the usual 8–12 Hz setup window |
Scenarios are deliberately fixed reference cases so visitors can compare this tonearm's 11.5 g effective mass with different compliance classes. Replace them with the actual cartridge values in Tonearm Match Lab before making a setup decision.
