    Ortofon Stereo Test Record

    Mit der neuen Test Record von Ortofon können Sie Ihre HiFi-Anlage in der natürlichsten Audioumgebung zu Hause überprüfen.
    Der Test Record enthält spezielle Testsignale, die für die Analyse der Tonabnehmerleistung und deren Interaktion mit Ihrem Tonarm und Plattenspieler entwickelt wurden.
    15 Tracks mit Frequenzgang-Sweeps, Referenztönen und 315-Hertz-Signalen mit steigender Amplitude zum Testen der Abtastfähigkeit

    THE TESTS
    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. Linier 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 frequencyresponse, 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 it is 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.
