Sennheiser EW-DX MKE 2 SET (Q1-9) Digital Wireless Lavalier / Handheld Set
Sennheiser EW-DX MKE 2 SET (Q1-9) Digital Wireless Lavalier / Handheld Set
This wireless lavalier microphone set consists of 2 x EW-DX SK (wireless bodypack transmitters), 2 x MKE 2 (omni-directional clip-on lavalier microphones), 1 x EW-DX EM 2 rackmount receiver (2 channels), and 2 x BA 70 rechargeable batteries.
Sennheiser EW-DX simplifies professional workflows by utilizing refined technologies and decades of research to deliver a digital UHF system that can be scaled with ease. With its advanced feature set and hardware options, classrooms, corporate campuses, and live productions benefit from a network-ready system designed to integrate seamlessly. The system quickly assesses the environment and uses equidistant channel spacing to deploy frequencies, while tools like Sennheiser’s Control Cockpit, Wireless Systems Manager, and Smart Assist App allow for remote monitoring. In-device charging, 12-hour battery operation, and switching bandwidth up to 88 MHz are just a few of the many features that make EW-DX the right tool for the job.
