The impact sound interrupter WBT-0718 has been developed to solve a problem which is generally known. And this is the problem of contact microphony.

Constant vibrations, i.e. caused by the impact sound of a loudspeaker cabinet inevitably affect all contact elements. Fluctuations in the transition resistances are the result.These fluctuations result in clearly audible non-linear distortions. Non-linear distortions are incalculable and hence they cannot be corrected. Those who set a high value on high-end inevitably have to deal with this problem.

WBT impact sound interrupter comes into operation in the decisive spot – it acts as an interrupter of the impact sound, and thus it releases contact elements.
