The Sennheiser EW-DX SKM-S Q1-9 is a digital handheld transmitter with mute switch, designed for professional use in the 470-550 MHz band. It guarantees stable transmission and excellent audio quality, even in dense RF environments.

ARTICLE N° 120884
The EW-DX SKM-S Q1-9 operates in the 470 - 550 MHz band, a range widely used in Europe for professional HF systems. This band generally offers good spectrum availability, particularly in theatres, live events or corporate installations.

Thanks to its digital transmission and latency of just 1.9 ms, it ensures accurate, consistent audio reproduction. Its built-in mute switch allows the microphone to be muted instantly (deactivated from the receiver if required), an essential feature for conferences and live events.
