This new family of wireless products represents a new important milestone in the search for innovative and at the same time simple to use products. The goal is to offer a series of variable frequency UHF wireless microphones that overcome, in the same price range, all the limitations of fixed frequency UHF models. The problems arising from use in areas where a frequency is disturbed by TV repeaters and the problems of component interchangeability have therefore been resolved. In short, more of a revolution than an evolution.
