Description
The Sennheiser EW-DX SKM (U1/5) Handheld Transmitter is a digital UHF transmitter body designed for Evolution Wireless Digital systems. Built without a power switch for tamper-resistant operation, it features a rugged metal housing and the Sennheiser Standard Capsule Interface to support a wide range of Sennheiser and Neumann microphone heads (capsule not included). A persistent E-Ink display keeps vital information visible even with the batteries removed, while charging contacts enable in-device charging for streamlined turnarounds. Powered by the BA 70 lithium-ion battery (sold separately), it delivers up to 12 hours of runtime. The SePAC codec provides a massive 134 dB input dynamic range, eliminating transmitter gain staging and keeping audio pristine from whisper to roar. Network-ready software, including Sennheiser Control Cockpit, Wireless Systems Manager, and the Smart Assist App, simplifies deployment and remote monitoring. With fixed 10 mW RF power, 1.9 ms latency, and up to 88 MHz switching bandwidth, EW-DX SKM offers dependable performance for education, corporate, and live production.
