The Ortofon test vinyl record is designed to allow you to check your Hi-Fi system in your home audio environment.
The record contains specific test signals developed to analyse the performance of the phono cartridge, as well as its interaction with your tone arm and turntable.
This Ortofon test record is designed to be played through your system with built-in RIAA equalisation. However, we recommend that you set the volume control to a moderate signal level.

* The recording has a constant velocity amplitude throughout the sweep.
1 to 4 - Frequency Sweep: A Tool for Checking Frequency Response
Several factors can affect frequency response, including cable capacity, phono cartridge loading, tracking force, and mechanical wear. For this reason, achieving a perfectly flat frequency response can be challenging. Sometimes, making slight compromises in loading can yield a better overall frequency response. Given the above, the signal should be clean throughout the sweep.
5 to 8 - Reference Tone for Channel Output Testing
With this standard reference signal, it is possible to verify the accuracy of the left and right channel connections, channel balance, and turntable speed.
9 to 14 - Tracking Ability Test, 315 Hz Lateral Modulation
These tracks contain a 315 Hz signal recorded at increasing peak amplitudes of 50, 60, 70, 80, 90, and 100 micrometers. Refer to the tracking ability value specified in your cartridge's technical data sheet. Your phono cartridge should be able to track the actual level without audible distortion. If there is a difference in tracking ability between the left and right channels, it may be necessary to readjust the tonearm's antiskating correction. If both channels fail to track properly, the vertical tracking force should be increased until no further improvement in tracking force can be achieved.
15 - Square Wave 2.7 m/sec Duty Cycle 3:7
When monitoring your cartridge's output with an oscilloscope, you will see a square wave precisely aligned if the cartridge connection is correct.
