Rated 4.9 (132 reviews)
Evolution Wireless Digital (EW-D) is Sennheiser’s entry digital UHF platform, using a 15 MHz tuning range (1785 to 1800 MHz), equidistant frequency grid and 134 dB transmitter dynamic range for gain-structure-free operation. The Smart Assist app handles setup over Bluetooth Low Energy. This set ships as a complete vocal radio mic system with handheld transmitter, rack receiver, PSU and rackmount hardware. Band variant: Y1-3, 1785 – 1800 MHz. Partly licence-exempt in the UK: 1795-1800 MHz is exempt, 1785-1795 MHz requires the Ofcom Shared PMSE licence.
