1.
Place the device in the desired location in the room.
Using an Ethernet cable, connect the device to a network
that supports PoE+.
Note: If your network doesnt support PoE+, you should
purchase a separate PoE+ injector or PoE+ enabled switch.
This connection provides the device
with power, data, and other IoT and SIP capabilities.
If you need video conferencing capabilities, use the USB
type B cable provided and connect the device to your PC.
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 the Stem
Control or in iOS, Windows, and Android apps. You can
also access the platform through your web browser by
typing in the products IP address.
Thats it! Table is all set up to work as a standalone device.

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 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 Tables 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).

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.

Overview

The Stem Table (model: table1) is a high-quality conference speakerphone designed for tabletops and flat surfaces, transforming any environment into a professional conference room. It is part of the Stem ecosystem, which includes other devices like Ceiling, Wall, Hub, and Control, allowing for flexible setup options either as a standalone unit or as part of a multi-device system.

Function Description:

The Stem Table is optimized for clear audio capture and playback in conference settings. It features nine beamforming microphones that perform real beamforming, focusing on the speaker in the room and canceling out other noise. An innovative downward-facing speaker provides amplified performance. The device is equipped with a directional array technology that dynamically adjusts to locate and steer towards a legitimate voice source, ensuring that the speaker's voice is heard best by the far-end of the call. During a call, blue lights on the light ring indicate the direction the audio beam is focusing on.
