Part of the Stem Ecosystem for conference rooms, the Shure Stem Ceiling is an elegant, beamforming microphone array that easily mounts on the ceiling of your conference room. It offers clear and highly intelligible speech capture with state-of-the-art sound quality that enhance the conferencing experience for all participants. The device connects to your local network with PoE+ (Power over Ethernet) or to a computer—in meeting rooms, collaboration areas, and huddle rooms.

Whether you want to keep your audio out of sight or show it off, the Stem Ceiling gives you the option to discreetly flush-mount the microphone to a ceiling tile or tie it into the design of the room in chandelier mode. The Stem Ceiling is compatible with all your favorite video-conferencing platforms, including Zoom, Microsoft Teams, Meet, and others. Since it does not have speakers, it is used for audio capture only.

An Advanced Conferencing Microphone Solution
  • The 100 beamforming microphones work together to provide full coverage with a narrow, medium, or wide pickup pattern that can be adjusted for the required coverage area.
  • Full-duplex transmission, voice-activity detection, and automatic tracking of the person speaking ensure intelligible speech capture.
  • The direction-finding algorithm determines the presence and direction of the person speaking and the beamforming algorithm points the microphone pickup in that direction, ensuring that everyone in the room can be heard clearly by the participants on the far end of the call.
  • Automatic gain control adjusts the volume of people close to and far from the microphones, while echo cancellation, de-reverberation, and background-noise reduction (Audio Fencing) ensure comfortable communication, free from distracting sounds.
Simple to Mount and Set Up—Easy to Use with Intuitive Controls
  • The Stem Ceiling comes with a square ceiling panel and a mounting kit for easy installation in your conference room.
  • Connect the unit to your local network that supports PoE+ (Power over Ethernet). This connection provides the device with power, data, and other IoT and SIP capabilities.
  • If your network doesn't support PoE+, you must use a separate PoE+ injector or PoE+ enabled switch (both available separately).
  • The unit powers up automatically, and when the blue lights turn solid, you’re ready to go. So, one simple cable is all you need.
  • The device can be remotely controlled via the Stem Control device (available separately).
Designed for the Modern Meeting Room
  • Visible to all participants in the room, an LED light ring with blue and red colors clearly indicate the status of the unit, so you know when you’re heard and when you’re not.
  • Slow-pulsing red lights show that the device is muted
  • Fast-pulsing red lights show that the device is being pinged.
  • Slow-pulsing blue lights show that the device is booting up.
Versatile Setup Options
Standalone Setup with Network

  • Using the included Ethernet cable, connect the device to your local network that supports PoE+. 

Standalone Setup with Computer

  • If you need video conferencing capabilities, use the included USB Type-B cable to connect the device to your macOS/Windows/Linux computer.
  • Note: You must also use a separate PoE+ injector or PoE+ enabled switch to provide power to the unit.

Networked Setup with Multiple Stem Ecosystem Devices in the Room

  • Follow the same instruction as with standalone setup with network.
  • When setting up multiple Stem devices in a room, you must use a Stem Audio Hub (available separately), as all communications between the devices and the far end are done through the Hub.
Need More Coverage?
The Stem Audio Ecosystem gives you freedom to customize audio coverage for perfect pickup in every type of room. It allows you to mix and match all Stem Audio devices until your room is completely covered.

  • Stem Table: If you prefer to keep your speakerphone on the table, this low-profile 9-microphone array performs real beamforming with a full-range speaker.
  • Stem Wall: If you prefer to keep devices off the table, this wall-mounted 15-microphone array performs real beamforming with full-range speakers and subwoofers.
  • Stem Hub: When you have more than one device in a room or you need more than just USB connectivity, Hub becomes the brains of the operation. Hub enables multiple units in the room to communicate with each other to function as an ecosystem.
  • Stem Control: This simple and intuitive user interface creates an enjoyable and familiar experience when controlling all the elements of your Stem Ecosystem. It lets you see data-rich statistics and reports behind the scenes. Stem Control also seamlessly integrates with all major video conferencing platforms.

Being that USB has a short length limitation, and this is meant to be ceiling mounted, and that PoE is needed for power anyway...can this be installed with an ethernet cable, and a simple PoE switch in a little "network" without a router? I've heard that it needs a router to be assigned an IP address.

The Shure Stem Ceiling Beamforming Microphone Array for Conference Room BH #SHCEILING1 must be connected to your local network that supports PoE+ (Power over Ethernet). This connection provides the device with power, data, and other IoT and SIP capabilities. If your network doesn't support PoE+, you must use a separate PoE+ injector or PoE+ enabled switch (both available separately).
