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 6.5 g, which places the arm in the low-mass range for matching work. The 229 mm effective length is relevant to alignment geometry and mounting-distance decisions. The database records a integrated headshell interface. Stored cartridge-weight support is 4–10 g.

Reference cartridge caseCartridge mass / complianceEstimated total massCalculated resonance
Low-compliance MC example8.5 g / 8 CU15.5 g14.29 Hz — above the usual 8–12 Hz setup window
Medium-compliance example7 g / 15 CU14 g10.98 Hz — inside the usual 8–12 Hz setup window
High-compliance MM example6.5 g / 25 CU13.5 g8.66 Hz — inside the usual 8–12 Hz setup window

Scenarios are deliberately fixed reference cases so visitors can compare this tonearm's 6.5 g effective mass with different compliance classes. Replace them with the actual cartridge values in Tonearm Match Lab before making a setup decision.
