Shure Stem Wall Noise-Canceling Wall-Mount Speakerphone Array

The Stem Wall is optimized for walls and furniture surfaces. It features 15 beamforming microphones located on the front of the device, two speakers located at both ends, and two subwoofers in the back.

This design ensures that the speakers and mics are separated to improve speech intelligibility.

The beamforming microphones feature voice-activity detection and automatic tracking of the person speaking to accurately capture speech within a 20' radius. Automatic gain control adjusts the volume of people close to and far from the microphones, while adaptive echo cancellation, dereverberation, and background noise reduction ensure comfortable communication, free from distracting sounds. The full-range speakers provide clear audio and high-output volume.

Part of the Stem Audio ecosystem for conference rooms, the Stem Wall is an elegant, 48" speakerphone that easily mounts on a wall or credenza, ideal if you prefer to keep devices off your conference table.

It connects to your local network with PoE+ (Power over Ethernet) or to a computer in meeting rooms, collaboration areas, huddle rooms, or even in unequipped conferencing spaces.
