Ortofon 2M Blue
Ortofon 2M Blue cartridge reference data for tonearm matching, compliance, tracking force and resonance setup.
Reference specifications
| Manufacturer | Ortofon |
|---|---|
| Model | 2M Blue |
| Type | Moving Magnet |
| Body mass | 7.2 g |
| Compliance at 10 Hz | 20 CU |

Setup context
Use this cartridge reference with the Tonearm Match Lab to estimate cartridge-tonearm resonance. The key setup inputs are body mass, tracking force and 10 Hz compliance.
Reference data is best-effort and should be checked against manufacturer documentation before critical setup decisions.

Model-specific matching analysis
Its 7.2 g body mass is included in every total moving-mass estimate below. The calculation uses 20 CU at 10 Hz; this value dominates how strongly resonance shifts with tonearm mass. The stored tracking-force reference is 1.8 g. The database classifies this cartridge as Moving Magnet.
| Tonearm effective mass | Estimated total mass | Calculated resonance | Interpretation |
|---|---|---|---|
| 6 g tonearm | 13.7 g | 9.61 Hz | inside the usual 8–12 Hz setup window |
| 10 g tonearm | 17.7 g | 8.46 Hz | inside the usual 8–12 Hz setup window |
| 14 g tonearm | 21.7 g | 7.64 Hz | below the usual 8–12 Hz setup window |
| 20 g tonearm | 27.7 g | 6.76 Hz | below the usual 8–12 Hz setup window |
| 25 g tonearm | 32.7 g | 6.22 Hz | below the usual 8–12 Hz setup window |
Calculation: f = 1000 / (2π√(M×C)), using cartridge mass, 0.5 g fasteners and the stated 10 Hz compliance. This is a setup estimate, not a laboratory measurement.
