Tonearm Match Lab

Estimates cartridge-tonearm resonance frequency. Inputs: effective tonearm mass (g), cartridge compliance (um/mN or CU), tracking force (g). Output: estimated resonance frequency in Hz and a compatibility rating. Practical resonance target is 8-12 Hz.

Compliance Estimator

Converts cartridge compliance rated at 100 Hz to the 10 Hz equivalent needed for resonance calculations. Input: 100 Hz compliance figure. Output: estimated 10 Hz compliance.

Tonearm Geometry Lab

Calculates tonearm alignment geometry for pivoted tonearms. Inputs: effective length, pivot-to-spindle distance, inner/outer groove radii. Outputs: null points, overhang, offset angle and tracking error. Supports Baerwald, Lofgren A/B and Stevenson alignments.

VTA & SRA Lab

Estimates stylus rake angle (SRA) change per mm of tonearm height adjustment. Inputs: effective tonearm length, arm height, stylus cantilever geometry. Output: estimated SRA change in degrees per mm of lift.

Data Explorer

Browse cartridge and tonearm reference data used by the public setup tools. Search and inspect published values that support resonance calculations, compliance work and alignment geometry decisions.

Measurement Lab remains hidden from public navigation while the module is being finalized. Development access remains available by direct route.
