Professional UHF Transmission and Precise S4-7 Frequency Range

A stable wireless connection is the foundation of every successful performance. The Sennheiser EW-D SKM-S uses modern digital UHF technology, which offers a wide range of up to 100 meters. In this version, the device transmits in the S4-7 frequency range, covering the spectrum from 630.000 to 662.000 MHz. The even distribution of frequencies effectively eliminates intermodulation interference. This means you can operate several wireless systems simultaneously without the transmitters interfering with each other. An integrated, easily accessible on/off switch also allows you to quickly mute or deactivate the microphone directly on stage.

Maximum Dynamics and Natural Sound Fidelity

During live performances or presentations, voices often change dynamically between quiet whispers and loud shouting. Thanks to the 134 dB dynamic range, the handheld transmitter faithfully reproduces every acoustic detail without the need to manually readjust the input level. Signal processing is performed with a professional 24-bit resolution and offers an extremely low system latency of just 1.9 milliseconds. This ensures that the speaker or singer experiences an absolutely direct and natural sound. Every word and every note reaches the audience clearly and understandably.

Robust All-Metal Housing and Smart App Control

Daily use on stage or at conferences puts considerable demands on equipment. The handheld transmitter's durable all-metal housing reliably protects the sensitive electronics from impacts. An AA battery is included in the delivery to provide power for the initial startup. Standard AA batteries provide up to 8 hours of operating time, while the optional BA 70 lithium-ion battery pack extends the operating time to up to 12 hours. The entire wireless system is configured via Bluetooth using the free Smart Assist App. Intelligent algorithms handle frequency selection and synchronization in the background, so that an operational connection can be established in no time, even without prior technical knowledge.
