The Sennheiser EW-D SKM-S R1-6 BASE SET is a foundational digital wireless system package providing a handheld transmitter body with mute functionality and a rackmount receiver, operating in the R1-6 band (520 to 576 MHz). Sold without a microphone capsule, this set is designed for users who prefer to select their own capsule—such as a specific Sennheiser MMD model—to tailor the sound characteristics to a particular vocalist or application. The handheld transmitter body features a durable metal construction, an OLED display, and a convenient mute switch for instant audio silencing during broadcasts or performances.

Leveraging the advanced EW-DX series technology, the system ensures high-fidelity 24-bit/48 kHz digital audio transmission with secure encryption and reliable RF performance via the receiver's Intelligent Antenna Diversity. This base set offers a cost-effective and flexible entry point into the premium digital wireless ecosystem, perfect for audio professionals who already have an inventory of microphone capsules or who require the ability to swap capsules for different events, all while benefiting from the latest wireless features and audio quality.
