BEAMTRACKING™ MICS IN DIVISIBLE SPACES
Tesira
A divisible or multi-purpose room is a large space that can be sectioned o with folding walls or
sliding doors to accommodate events and meetings of dierent sizes. Present in many corporate
facilities, universities, and hospitality settings, they are an excellent option for maximizing
available space.
Typically, a more flexible physical space leads to increased complexity in the AV system in
order to accommodate all of the possible scenarios. While system integrators can oset many
challenges a divisible space presents, microphone placement/aiming can be quite dicult.
What’s good for one room size may include dead spots when the space is reconfigured.
Beamforming microphone arrays can alleviate some of those challenges, but can quickly become
cost prohibitive if each possible room configuration has to include one. Plus, mixing the outputs
of multiple beamforming arrays when the room is combined presents another set of hurdles.
Now there’s a better way: Tesira TCM Beamtracking™ microphones.

Our TCM microphones provide exceptional audio quality to the far end while simultaneously achieving consistent
room coverage. They let people act naturally — stand up, sit down, face the whiteboard, or walk around the table —
without negatively impacting the far-end audio quality. Unlike traditional microphones, Beamtracking microphones
track people as they move, and don’t force them to stay where the lobes are aimed.
Specific to divisible spaces, another key dierentiator of our Beamtracking microphones is the ability to
independently route microphone trac via Tesira software to anywhere it’s needed. Even daisy-chained TCM
microphones can be routed independently. For example, a small space with a TCM-1 on one side of a divider and
a TCM-1EX on the other side can be configured in our matrix mixer to treat each microphone as a separate audio
source, or to combine them when the room is combined. Another option is to use our room combiner block, a
powerful, easy-to-use tool that manages the signal routing and control of combinable/divisible spaces. It can
support a maximum of 32 rooms in numerous configurations, with combinable levels, mutes, and source tracking.
If you’re unsure of how many Beamtracking microphones are needed to provide adequate coverage — or where
they should be mounted — we oer a TCM coverage calculator on Cornerstone, our support website.
Tesira is an ideal platform for divisible spaces, because it’s particularly adept at supporting situations that require
rapid reconfiguration. Through the use of presets or room combiner block, the entire AV system, including
microphone routing, can be easily reset according to how the rooms are divided or combined for the next meeting.
