Compact Professional Digital Bodypack: Sennheiser EW-DX SK (Q1-9)
The Sennheiser EW-DX SK (Q1-9) is an enterprise-grade digital bodypack transmitter designed to deliver pristine wireless audio transmission for theatrical productions, corporate presentations, houses of worship, and live musical performances. Featuring a lightweight yet durable all-metal frame, this bodypack connects effortlessly to your choice of lavalier, headset, or instrument cable via a standard locking 3.5 mm TRS connector.
Operating in the clean Q1-9 Frequency Range (470.2 – 550.0 MHz), this bodypack transmitter from our Sennheiser evolution wireless series catalog takes full advantage of Sennheiser’s equidistant frequency grid. By removing intermodulation distortion, the EW-DX system allows maximum channel density across crowded RF environments without needing complex frequency calculations.
