Shure ULX-D Digital ULXD4 and ULXD2 w/ SM58

The Shure ULX-D Digital Wireless System featuring the ULXD4 receiver and ULXD2 handheld transmitter with the SM58 capsule is a professional-grade solution designed for high-performance, reliable wireless audio transmission in demanding live sound environments. Known for its pristine audio quality, secure transmission, and scalable features, this system is widely used in concert venues, corporate AV setups, educational institutions, and houses of worship. The inclusion of the SM58 capsule — an industry-standard vocal microphone — ensures rugged dependability and excellent sound tailored for speech and vocal performances.

The ULXD4 is a half-rack, single-channel digital wireless receiver that delivers 24-bit/48 kHz digital audio with extremely low latency and a wide dynamic range. It operates in the UHF band and uses advanced digital modulation to provide secure, interference-free performance. The receiver includes features like AES-256 encryption for secure signal transmission, making it suitable for confidential environments or corporate boardrooms. Additionally, its automatic frequency selection and RF interference detection simplify setup, while comprehensive networked control and monitoring — via Shure’s Wireless Workbench software or third-party control systems — allow for centralized configuration in complex multi-channel systems.

Paired with the ULXD4, the ULXD2 handheld transmitter houses the legendary SM58 dynamic capsule. The SM58 has a cardioid pickup pattern designed to isolate the main sound source while minimizing background noise, making it ideal for live vocals in loud stage environments. The transmitter’s build is robust and stage-ready, and its digital transmission ensures that audio fidelity remains high from mic to receiver. The transmitter operates on rechargeable lithium-ion batteries or standard AA batteries, offering flexible power options with long runtime and accurate metering.

Altogether, the Shure ULX-D Digital ULXD4 and ULXD2/SM58 system offers excellent clarity, security, and reliability in a streamlined, modern package. It’s especially appealing to audio professionals who require scalable, networked wireless systems that are easy to deploy and configure without sacrificing sound quality or durability. Whether for touring rigs or permanent installations, it stands out as a top-tier wireless microphone solution.
