Frequently Asked Questions
For all distance coverage questions, we recommend utilizing our RoomDesign tool. When designing your room, Ceiling coverage is estimated based on a standard 9’ ceiling. Actual microphone pickup coverage and quality will always vary depending on the acoustical treatment of any room.
Yes, our RoomAdapt tool allows you to instantly optimize every Stem device in the room at the press of a button. When you initiate RoomAdapt, each device in the room will play a chirping sound. While chirping, the devices are analyzing the acoustics, audio pickup, and reverberance from different parts of the room. That information is used to adapt and adjust each individual device to work optimally in reference to the particular placement of each device in the room. If you want a deeper dive into RoomAdapt check out our blog on [How To] Instantly Tune Your Conference Room Audio.
Yes, Stem Hub has a connectivity option to integrate with Dante. Hub is the only Dante enabled device in the ecosystem and provides a single out channel for the entire room.
When there are multiple Stem devices in a room, Hub will control and process all the audio signals coming from each device in the room. The Hub replaces the computer’s speaker and mic.
Yes, yes, and yes! You can turn off a device’s directional lights through the device or room settings on the ecosystem platform. Instructions on how to disable directional lights can be found on page 7 of the Stem Audio platform user manual.
Control is an optional support device which will be used whenever you want to add a dedicated meeting control device in the room. Control has full access to the ecosystem platform, giving you the ability to set-up, monitor, and manage your rooms and devices. Control also has video conferencing functionality so you can leave it in the room for users to conduct push-to-start meetings. Control is Zoom Rooms compatible.
Our devices allow you to mix and match them into any room for customized coverage. When you are installing your combination of Stem devices in a room, you will plug them in, find them on the network through the ecosystem platform, and assign them to a room so they all know to work together as one ecosystem in that room. You can always reference our blog on [How To] Setup Your First Stem Room in Minutes to learn more.
If you are using a Stem Table and Wall (both have built-in speakers) you won’t need to install additional external speakers. However, if you only want to install Ceiling devices in the room, you will need to connect external speakers to the Hub in the room for sound.
Yes, Hub can be used with up to three audio devices (Table, Ceiling, Wall) for SIP conferencing with unlimited Control devices. For video conferencing, Hub can be used with up to five audio devices and unlimited Controls. In future firmware updates we will be increasing the number of audio devices that can be used in a single room.
No, there is no additional plate option but all Stem devices are equipped with a Kensington lock to secure them to their installed location.
The optimal height for mounting Wall is at mouth-level of meeting participants in the room. This will depend on chair height and if the majority of participants will be standing or sitting.
What keeps Ceiling hanging level to the floor when it’s suspended from the ceiling? Can it be dusted?
Ceiling is connected by a suspension wire that screws directly into the center of the device. Our engineers have designed Ceiling to evenly distribute the weight of the device so that it stays level when suspended in chandelier mode. Yes, Ceiling and all other devices can be dusted with a dry cloth or duster.
Network & Connectivity
When an update is available, we will send out the update to all devices. The devices will then search the network for any available updates and automatically update themselves at a time when they are not currently in use.
Since the devices are connected to your network (just like your video conferencing), if your network disconnects then yes, you will lose audio in the room. Once your network connection is re-established the devices will automatically find the network and reconnect.
You can absolutely connect directly to the computer via USB. However, we highly recommend that you pair a Ceiling to a Hub. This will eliminate the need to run a long USB cable from your ceiling to your computer.
I noticed that the Stem Wall, Table and Ceiling have an Ethernet port and USB. What is the USB connector for?
Table’s USB connectivity option is to connect directly to your PC if you want to use it as a standalone device for video conferencing. All Stem devices have PoE+ connectivity for power and data in addition to an optional USB connection if you want to use a device for standalone video conferencing.
When plugging in your first Stem device, you will be prompted to choose a security setting by either setting up a password-protected organization or default settings. If you create an organization, only devices within your password-protected organization can communicate and control one another. To protect your privacy Stem devices come with encryption security measures.
The Hub comes with non-amplified analog out connection. Therefore, if you have existing external speakers you can connect the speaker amplifier directly to the Hub. The Hub comes with the terminal block adapter — the adapter provides two negative, two positive and one ground terminal.
Make sure you refrain from using a switch with EEE capabilities, also known as Green Ethernet and IEEE802.3az switch, unless this feature can be disabled in a managed switch. Many EEE switches do not perform the negotiation properly and can result in poor synchronization and dropouts.
Absolutely. You can SIP-enable an individual device or a room via the Hub as long as your SIP provider allows basic 3rd party SIP devices. You can dial SIP calls directly on Control or the ecosystem platform which is available in the app store for Android, iOS, and via HTML.
Of course! The speakers in each device will play whatever you want them to based on what your Hub is connected to. Feel free to play your favorite song on your computer using the streaming platform of your choice.
