Shure Stem Ceiling

Stem Ceiling is a state-of-the-art ceiling microphone array that delivers exceptional audio quality in large conference rooms. Featuring a dense array of 100 microphones, Stem Ceiling can be configured with three different beam patterns: wide, medium, and narrow. This flexibility allows you to optimize audio capture for various room sizes and seating arrangements.

Stem Ceiling's advanced beamforming technology ensures that only the desired voices are picked up, while background noise and echo are minimized. This results in clear and intelligible audio, even in noisy environments. Additionally, the microphone array can be easily integrated with popular video conferencing and collaboration platforms.

Whether you choose the low-profile or chandelier-style mounting option, Stem Ceiling offers a sleek and discreet solution for enhancing your conference room audio.
