The Audio-Technica fourth-generation 3000 Series wireless systems give you the power and flexibility to operate within the congested UHF spectrum. 3000 Series systems have an operating range of 300' (100 m) and are available in two frequency bands – DE2 (470–530 MHz) and EE1 (530–590 MHz) – that provide a class-leading 60 MHz tuning range, which is more than twice that offered by the previous 3000 Series models.
