The Sennheiser EW-D SKM-S BASE SET (Q1-6) is a professional digital wireless handheld microphone system that represents the entry point into Sennheiser's Evolution Wireless D series. As a B-stock item, it has been factory recertified to ensure full performance and reliability, potentially with minor cosmetic imperfections. The set includes a handheld transmitter with an integrated digital dynamic microphone capsule and a compact rack-mountable diversity receiver. Operating in the Q1 frequency band (548-572 MHz), it leverages 24-bit/48 kHz digital audio transmission to deliver pristine, clear sound with high dynamic range and extremely low latency (<3 ms). This digital link provides robust immunity to interference and eliminates the compander noise artifacts associated with analog wireless systems.

The handheld transmitter, based on the SKM-S platform, features a robust metal body and a high-quality dynamic capsule tailored for vocal reinforcement. It includes an OLED display for clear visibility of settings, intuitive menu navigation, and controls for power, channel selection, and audio gain. The receiver is a 1/4 rack-width unit that can be combined with three others in a single rack space using the included adapter. It offers both XLR and 6.3mm outputs, an easy-to-read color display, and features like automatic frequency coordination and remote control via smartphone app (with optional Bluetooth dongle). The system supports secure 128-bit AES encryption for protected transmissions, making it suitable for corporate and broadcast applications.

Designed for ease of use and future-proof performance, the EW-D system includes intelligent networking capabilities; multiple systems can be linked via an Ethernet cable for centralized control and frequency management. The set comes pre-paired and ready to use out of the box. As a recertified digital wireless system from a leading manufacturer, the EW-D SKM-S BASE SET offers musicians, presenters, and production companies exceptional value, providing the audio fidelity, reliability, and advanced features of modern digital wireless technology at an accessible price point for live sound, installed AV, and broadcast applications.
