How it works<\/strong><\/p>\n

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.<\/em><\/p>\n<\/div>\n<\/div>\n

1-4 Frequency sweep – A tool for checking frequency response
\n<\/strong>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.<\/p>\n

5-8 Reference tone for testing channel output
\n<\/strong>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.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

9 -14 Tracking ability test, 315 Hz lateral modulation<\/strong>
\nThese 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\u2019s 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.<\/p>\n

15. Square Wave Form 2.7 msec duty cycle 3:7
\n<\/strong>When monitoring the output of your cartridge with an oscilloscope you\u2019ll then see a square wave located precisely above each other if the connection from the cartridge is correct.<\/p>\n
