Overview

Optimized for tabletops and flat surfaces, the Stem Table is a high-quality conference speakerphone that turns any environment into a professional conference room. Equipped with nine microphones that perform real beamforming and an innovative downward-facing speaker for amplified performance, Table takes the quality of your meetings to the next level.

Setting Up

All Stem endpoints can be used as solo standalone devices or in unison with other devices within the Stem ecosystem. If you plan on using this device as an individual unit, then follow the standalone setup instructions. If you plan on using multiple Stem devices in your room, then skip ahead to the multiple device setup instructions.

Standalone Setup (option 1)

1. Place the device in the desired location in the room.

2. Using an Ethernet cable, connect the device to a network that supports PoE+. This connection provides the device with power, data, and other loT and SIP capabilities. Note: If your network doesn’t support PoE+, you should purchase a separate PoE+ injector or PoE+ enabled switch.

3. If you need video conferencing capabilities, use the USB type B cable provided and connect the device to your PC.

4. Lastly, we recommend you complete setting up your room via the Stem ecosystem platform. For more information on setting up your room, you can visit stemaudio.com/manuals or stemaudio.com/videos
   Note: The ecosystem platform is available on Stem Control or in iOS, Windows, and Android apps. You can also access the platform through your web browser by typing in the product’s IP address. If you need help finding your IP address press and hold down the Vol+ and Vol – for 5 seconds and the IP address will be read out.

5. That’s it! The table is all set up to work as a standalone device.

Multi-Device Setup (option 2)

1. Place the device in the desired location in the room.

2. Using an Ethernet cable, connect the device to a network that supports PoE+. This connection provides the device with power, data, and other loT and SIP capabilities.
   Note: If your network doesn’t support PoE+, you should purchase a separate PoE+ injector or PoE+ enabled switch.

3. When setting up multiple Stem devices in a room, make sure you have a Hub. All communications between the device and the far end will be done through the Hub, so no USB connection is needed.

4. You must complete setting up your room via the Stem ecosystem platform. For more information on setting up your room, you can visit stemaudio.com/manuals or stemaudio.com/videos Note: The ecosystem platform is available on Stem Control or in iOS, Windows, and Android apps. You can also access the platform through your web browser by typing in the product’s IP address. If you need help finding your IP address press and hold down the Vol+ and Vol- for 5 seconds and the IP address will be read out.

5. That’s it! Table is all set up to work within the Stem ecosystem.

Using Table

The Directional Array
During a call, Table uses proprietary beamforming technology to locate a legitimate voice source and to steer an array towards it. This allows the Table to focus on the speaker in the room and cancel out all other noise. The beamforming process is dynamic as it adjusts the direction of the array when the source of sound changes or moves. In a call, when a voice is detected in the room, one or multiple blue lights located in the light ring will indicate which direction the Table’s audio beam is focusing on. This is the direction that will be heard best by the far end of the call (the person you are talking to).
Volume Control
Speaker
Change the speaker volume by using **+** to increase, or **-** to decrease the volume.
Mute
To mute Table’s microphones during a call, press located on the top of the device. When muted, the light ring on the device will slowly pulse red. To (J) unmute, just press again.
