Ortofon Stereo Test Record

Ortofon Test Record

Ortofon’s Test Record is designed to allow you to verify your HiFi system in the most natural audio surroundings at home. The Test Record contains special test signals developed for analyzing cartridge performance as well as its interaction with your tonearm and turntable.

Before testing your cartridge, please verify the HiFi system’s functionality. The left speaker should be connected to the left amplifier channel and vice versa; both speakers should work in phase and be optimally positioned in the room.
The Test Record is designed to be played through your system with in-built RIAA equalization. Volume control is recommended to be set at a moderate signal level.

Please refer to your turntable and tonearm’s instructions for correct installation and alignment, adjust tonearm to be parallel to the record surface, set Vertical Tracking Force and antiskating according to the cartridge’s recommended technical data, and adjust stylus overhang.

How it works

Watch the video where Leif Johannsen, Ortofon's Chief Officer Acoustics and Research, explains how to set up and align your high-end cartridge correctly.

1-4 Frequency sweep - A tool for checking frequency response
There are several factors which can affect frequency response, including cable capacitance, cartridge loading, tracking force and worn parts. Because of this, it can be difficult to achieve perfectly flat frequency response. Sometimes by making small compromises in the cartridge loading, a better overall frequency response can be achieved. Considering the above the signal must be clean throughout the sweep.

5-8 Reference tone for testing channel output 
With this standard reference signal is it possible to check the correctness of the connections of the left and right channels, channel balance and speed of the turntable.

9 -14 Tracking ability test, 315 Hz lateral modulation
These tracks contain a 315 Hz signal, recorded at increasing pick amplitudes of 50, 60, 70, 80, 90 and 100 micrometers. Please refer to your cartridge’s tracking ability value specified in the technical data sheet. Your cartridge should be able to track the actual level without audible distortion. Inability to track can be heard as a departure from a pure tone or a sputtering and intermittent tone. To determine if it is one or both channels, the balance control can be utilized. In case of differing tracking ability in the left and right channels it is probably necessary to readjust the anti-skating correction of the tonearm. If both channels fail to track properly, then vertical tracking force should be increased until no further improvement of tracking force can be obtained.

15. Square Wave Form 2.7 msec duty cycle 3:7
When monitoring the output of your cartridge with an oscilloscope you’ll then see a square wave located precisely above each other if the connection from the cartridge is correct.
