Measuring a cartridge with the Ortofon Test Record

[milanjeromos]

Hello everyone! I would like to measure my Ortofon Music Red cartridge with an Ortofon Test Record. I tried looking in the SJPlot but this test record is not available. How would I go about measuring it? I have the recording chain already set up.

This is the test record:

The Ortofon test record has a wrong frequency response and is misleading

You can use this formula in the Audacity nyquist prompt twice to correct for the drop between 3000 Hz to 800 Hz. Then use SJplot; you can use TRS1007 as record. Use track 3 and 4 (the second pair L and R).

(biquad-m *track* 9.08612614639649000E-01 -5.22931473883012000E-01 -3.44913691685509000E-01 1.00000000000000000E+00 -6.04500910000000000E-01 -3.90945930000000000E-01)

After this it is quite in accord with my CA-TRS1007.
