Designed for ease of use and high scalability, the EW-DX series digital wireless brings Sennheiser's rock-solid performance and signature audio quality to your corporate, academic, or live performance application. The EW-DX 835-S Set includes two handheld transmitters with MMD 834 mic capsules, an EW-DX EM 2 rackmount receiver, and a pair of BA 70 rechargeable batteries. Sennheiser's integrated Auto Scan technology takes the work out of channel management by assigning equidistant channels making better use of the frequency range and avoiding annoying intermodulation interference. The system is controllable via tablets and smartphones (sold separately) using the Smart Assist app. Alternately, WSM (Wireless Systems Manager) and Control Cockpit software (sold separately) offer advanced detailed system overviews of complex networked environments. EW-DX also features Ethernet control ports and AES-256 encryption so you can feel secure transmitting on IT networks. Since the audio is what matters, the system has been engineered with a 134 dB dynamic range, low noise floor, and a latency of only 1.9 ms so you hear everything, on time, as intended. With a 12-hour runtime and support for network-enabled charging (charger sold separately), the EW-DX makes power problems a thing of the past while defining the future of wireless.
