Sennheiser EW-D SKM-S Base Set: Professional Digital Wireless Handheld System

The Sennheiser EW-D SKM-S Base Set is a flagship digital wireless microphone system from the Evolution Wireless Digital series. Designed for professional vocalists, presenters, and educators, this base set provides the foundation for a premium wireless setup. It combines high-fidelity 24-bit digital audio with an expansive dynamic range, eliminating the need for manual sensitivity adjustments on the transmitter. The "Base Set" configuration includes the receiver and handheld transmitter but is provided without a microphone capsule, allowing users to choose the specific Sennheiser or Neumann head that best fits their vocal application.

Professional Digital UHF Performance and Control

The EW-D series utilises an equidistant tuning grid, a technology previously reserved for Sennheiser’s high-end Digital 6000 and 9000 systems. This removes the complexity of frequency coordination by allowing channels to be placed at equal intervals (600 kHz apart) without intermodulation interference. The system offers a massive 134 dB dynamic range, ensuring that even the most subtle nuances or powerful vocal peaks are captured with pristine clarity. With 1.9 ms of ultra-low latency, the audio remains natural and immediate for live performances.

System management is streamlined through the Sennheiser Smart Assist App, which connects via Bluetooth Low Energy. This allows for automated setup, remote monitoring of battery life, and frequency scanning directly from a smartphone or tablet. The system operates in the UHF spectrum, providing enhanced range and reliability compared to 2.4 GHz digital systems. It is capable of scaling up to 90 simultaneous channels within its 56 MHz tuning bandwidth, making it suitable for both small venues and large-scale multi-channel installations.

Robust Hardware and Modular Versatility

The EW-D EM receiver is housed in a rugged, half-rack metal chassis, suitable for both tabletop use and professional rack mounting. It features a high-contrast OLED display for easy navigation in low-light environments. The EW-D SKM-S handheld transmitter is also built with a durable metal housing and includes a dedicated mute switch for user control on stage.

Because the transmitter features an interchangeable capsule design, it is compatible with the full range of Sennheiser Evolution Wireless Digital microphone heads (such as the MMD 835, 935, and 945) as well as premium Neumann capsules. The transmitter provides up to 8 hours of operation with standard AA batteries, which can be extended to 12 hours with the optional BA 70 rechargeable lithium-ion battery pack.
