Ortofon Stereo Test RecordOrtofon’s new 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 record surface, set Vertical Tracking Force and antiskating according to the cartridge’s recommended technical data, and adjust stylus overhang.Each side of the record consists of 15 tracks which have been cut from 1-4 and 5-15:
1. Frequency Sweep Left Channel 800 Hz – 50 kHz. Log. 28 sec. Linear cut* (800 – 20000 Hz ±1,5 dB)
2. Frequency Sweep Right Channel 800 Hz – 50 kHz. Log. 28 sec. Linear cut* (800 – 20000 Hz ±1,5 dB)
3. Frequency Sweep Left Channel 800 Hz – 50 kHz. Log. 28 sec. Linear cut* (800 – 20000 Hz ±1,5 dB)
4. Frequency Sweep Right Channel 800 Hz – 50 kHz. Log. 28 sec. Linear cut* (800 – 20000 Hz ±1,5 dB)
5. Reference tone 1000 Hz 5 cm/sec rms Left
6. Reference tone 1000 Hz 5 cm/sec rms Right
7. Reference tone 1000 Hz 5 cm/sec rms Left
8. Reference tone 1000 Hz 5 cm/sec rms Right
9. Tracking ability, lateral 50 μm peak
10. Tracking ability, lateral 60 μm peak
11. Tracking ability, lateral 70 μm peak
12. Tracking ability, lateral 80 μm peak
13. Tracking ability, lateral 90 μm peak
14. Tracking ability, lateral 100 μm peak
15. Square Wave Form 2.7 msec duty cycle 3:7
* The record has a constant velocity amplitude throughout the sweep.
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.
After successful completion of the above test procedures, you can ensure that your cartridge is optimized. Still the human ear is very sensitive to difference in tone distortion; its level depends on the stylus condition and record wear.$49.99Ortofon Stereo Test RecordBuy Now

Currently, Ortofon produces four different cartridges: moving magnets, designed and manufactured by Ortofon since 1969; moving coils, still proudly handcrafted; SPU cartridges, refined in the tradition of the first-ever moving coil cartridges; and mono cartridges, a tribute to the lasting qualities of mono records from the 1950s and 60s reissued today.
Ortofon moving magnet cartridges are economical, feature sophisticated styli, light and rigid cantilevers, and their advanced magnetic circuitry produces state-of-the-art sound quality within the magnetic category. The Ortofon 2M series combines form and functionality, designed for precise and accurate retrieval of information at an affordable price. Ortofon 2M cartridges begin with the most basic and affordable model, the 2M Red, and progresses upwards through 2M Blue, 2M Bronze, and 2M Black, as well as offering a Mono cartridge and several other variations.
Ortofon moving coil cartridges demonstrate the company’s commitment to the continuous refinement of analogue sound quality. Unlike other phono cartridges, the moving coil cartridge is painstakingly handcrafted—each of the four coils contains anywhere between 11 to 24 turns of wire hand-wound beneath a microscope. Throughout its history, Ortofon has introduced more than 300 moving coil models up to the favorites of today, the Cadenza and Quintet series. Like the 2M series, both the Cadenza MC and Quintet MC series offer several cartridges to fulfill various needs and budgets. Following an easy scheme starting with Mono and Red as the most basic and affordable models, the series moves through Blue, Bronze and finally, Black.
Supporting their wide selection of cartridges, Ortofon designs and manufactures a range of tonearm cables, stylus guards, and replacement styli—always ensure you purchase the genuine article by recognizing the large Ortofon logo on the stylus body.
