Clearaudio Cartridge Break-In Test Record

A pickup system requires a certain break-in period to achieve the best reproduction characteristics. This settling time depends on the specific pickup - from construction and from the sampled signals during this time. Usually, this break-in period for a phono cartridge with a music signal is about 40 to 100 hours. This settling time can be shortened significantly, however, when pink noise is used as a signal in an endless groove.

To this end, the Clearaudio Cartridge Break-In Record provides 6 endless grooves with a pink noise signal (tracks 5,6,7,9,10 and 11). In addition, 240 seconds are added Pink noise signals for measurements of the entire playback system available (Track 14).

To test the frequency response of a pickup is a moving (sweep) sine test signal from 20 Hz to 20 kHz (Track 3). The total noise of the playback system can be tested with an empty record without signal "silence" (Track 4 and 13) (duration 300 seconds). Optimization of the anti-skating force adjustment allow Tracks 8 and 12 Both channels include a 316 Hz sine wave signal with a continuously changing phase difference from 0 to 360 grad on the diamond sample movement is repeated this way, changes of horizontal to vertical movement. The amplitude increases from -22 dB to + 8 dB.
