Vinyl records have a surface static electricity charge created by friction. Two common sources of friction that creates static build-up are the stylus drag that occurs during record playback, as well as removing records from their jacket and sleeve.
By emitting both positive and negative ions in a controlled fashion from its dual outlets, the ION-001 ionizer unit effectively neutralizes and removes static electricity from the record surface.
The unit is completely silent during playback, and can also remove charge on Compact Discs.

The ST-50’ s cleaning gel is made of a urethane resin developed
specially for the purpose of atmospheric micro-dust control in
clean rooms. Extremely effective cleaning properties are required
to meet the specified standards for such applications. The ST-50
gives you the very best in stylus cleaning performance.
Many stylus cleaners apply excessive force to the stylus and cantilever during the cleaning process. The DS Audio ST-50 cleans
your stylus at the tracking force set on the tone arm.
