This wireless monitoring set’s receiver uses adaptive diversity
technology. The earphone cable serves as a second antenna, which
considerably reduces the number of drop-outs. Combined with
IE 4 ear-canal phones for precise sound reproduction, EK 2000 IEM
conveys an authentic acoustic pattern of live sound and allows you
to monitor your own performance perfectly.
