Rigorously engineered to meet the needs of demanding professionals working in business and educational settings, houses of worship, or on stage, the Sennheiser EW-DX SK-SKM-S BASE SET is a dual-channel digital UHF wireless system with an impressive feature set designed to simplify your workflow while delivering uncompromising audio quality. This configuration includes a 1/2-rack, dual-channel receiver, one bodypack transmitter without a lavalier, and one handheld transmitter without a mic capsule—so you can choose your preferred lav mic and mic capsule for the application.

With a remarkable 134 dB dynamic range, the transmitters can handle just about any input level you throw at them. The wide 80 MHz tuning range, intelligent switching diversity, auto-scan, equidistant tuning grid, and Link Density mode work to provide rock-solid wireless performance and massive channel counts, even in challenging RF environments. Bluetooth capabilities allow you to remotely sync components and change settings from your phone using the Smart Assist app, while Sennheiser's Control Cockpit and Wireless Systems Manager software provide computer-based control for more extensive networked setups. The EW-DX is backward-compatible with EW-D
