The Shure Stem Ceiling is an advanced, network-connected microphone array designed to be installed in conference rooms, huddle spaces, and classrooms to capture clear audio for videoconferencing, conferencing, and voice reinforcement. As part of the Shure Stem ecosystem, it is a modular, all-in-one solution that combines multiple microphone elements, a digital signal processor (DSP), and a network interface in a single low-profile enclosure. Its primary technology is beamforming, which uses its array of microphones to dynamically create focused pickup patterns (beams) that steer toward active speakers while suppressing noise and reverberation from other directions. This results in superior audio clarity and intelligibility for remote meeting participants.

The device is designed for simple integration into modern AV-over-IP environments. It connects via a standard Ethernet cable using the common Dante audio networking protocol, carrying both power (PoE) and high-quality digital audio to a compatible conferencing system or DSP. Installation is straightforward, with the unit typically mounted flush to a standard T-bar ceiling grid. Control and configuration are managed through an intuitive web interface or the Stem companion app, allowing users to adjust settings like gain, beam steering behavior, and privacy modes (e.g., mute via LED indicator) without specialized software.

The Stem Ceiling exemplifies the trend towards decentralized, intelligent audio endpoints in unified communications. By placing high-quality, processed audio capture directly in the optimal location above the conference table, it eliminates the need for tabletop microphones and complex wiring, creating a cleaner room aesthetic. Its scalability allows multiple units to be used in larger rooms for extended coverage. This product is engineered to solve the common challenge of poor audio in video meetings, providing a professional, reliable, and easy-to-manage audio foundation for hybrid work environments.
