With the help of a pulse irradiation technology, which was developed over the course of around 25 years out of the therapy of hundreds of professionals, a Converter, together with Vital products, can be provided with bioresonant frequency. The result is a stimulus-reaction vitalisation frequency, which is activated if necessary (where there is damage or disturbance) and neutralises potentially harmful frequencies. Which of the different frequencies are released depends on the task of the respective Converter.
