Stem Audio Table Conference Room Speakerphone

• Place the Stem Table where you want it on your table and connect it 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 light turns solid, you’re ready to go. So, one simple cable is all you need!
• The top of the device houses two volume + & – buttons that let you increase or decrease the volume of what you hear in your room.
• A mute button cuts the microphone, preventing other people in the call from hearing what is being said in the room.

• Visible to all participants in the room, a large LED light ring with blue and red colors clearly indicates the status of the unit.
• Slow-pulsing red light shows that the device is muted and fast-pulsing red light shows that the device is being pinged.
• During a call, as you walk around the room or different people talk in the room, the blue light moves around the ring, orienting itself towards the person who is speaking and indicating that the device hears them and is picking them up clearly.

• The 9 beamforming microphones work together to provide a 360° coverage within a 10′ range.
• 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.

• The Stem Table utilizes neural networks to improve echo-canceling, dereverb, and noise cancellation algorithms.
• Adaptive echo canceler removes echo to achieve smoother reciprocal conversations.
• Noise reduction eliminates noise and conveys only voice.
• Dereverberation conveys clear voice by reducing reverberation caused by the acoustics of the room.

Standalone Setup with Network

• Using an 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.

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 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 Ceiling: Whether you want to keep your audio out of sight or show it off, Ceiling offers a 100-microphone array with a design that gives you the option to discreetly flush-mount the device to a ceiling tile or tie it into the design of the room with chandelier mode.
• 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
