MicroMara Posted January 29 Share Posted January 29 Ordered a cartridge break in record today , let´s hear if it works for my collection of pick - ups ... Clearaudio Cartridge "Break In" Test Record Pimp your turntable - with the Clearaudio Cartridge "Break In" Test Record you have for the first time the possibility to perfectly calibrate, adjust and quickly record the system of your turntable. Whether pink noise or various test signals - the calibration LP offers everything the analog heart needs for the optimal adjustment of the entire system. A pickup system needs a certain play-in time to achieve the best playback characteristics. This break-in time depends on the particular cartridge design and on the sampled signals during this time. As a rule/usual, this play-in time of a cartridge with a music signal is about 40 to 100 hours. However, this break-in time can be shortened considerably by using a pink noise in an endless groove as the signal for breaking in a pickup. Now tedious recording is a thing of the past. For this purpose we have provided a total of 6 endless grooves with pink noise signal on our "Cartridge Break In Record" (tracks 5,6,7,9,10 and 11). In addition, 240 seconds of pink noise signals were provided for measurements of the entire playback system (track 14). A sliding (sweep) sine test signal from 20 Hz to 20 kHz is used to test the frequency response of a pickup (Track 3). The total noise of the playback system can be tested with an empty groove without signal " silence" (track 4 and 13) (duration 300 seconds). Optimization of the antiskating force setting allows tracks 8 and 12. Both channels contain a 316 Hz sine signal with continuously changing phase difference from 0 to 360 degrees. In this way, the scanning diamond motion repeatedly changes from horizontal to vertical motion. The amplitude increases from -22 dB to + 8dB, corresponding to a maximum speed of 9.81 cm/s or an amplitude of 5o µm peak horizontally or vertically. 3 Quote Link to comment Share on other sites More sharing options...
