The first enemy records — dust: invisible to the eye, it becomes “audible” as soon as the needle touches the disc player, particularly a high level. Crackles, rales, crepitation, in this case, the typical noise design. In addition to the regular wiping of the disc with a soft cloth, install the cartridge a sort of “janitor” — a fabric or suede tab, which will slide on the plate in front of the needle, cleaning the audio track. It is better to fix rubber ring: always can be removed to shake out or wash.
