ClearOne Debuts Patented Ceiling Tile Beamforming Mic Array

ClearOne just launched a patented Beamforming Microphone Array Ceiling Tile, the BMA CT.

The BMA CT also has a unique feature in that it includes a built-in 2×10-watt power amplifier to drive loudspeakers. The BMA CT debuted at ISE 2019 from February 5-8 at ClearOne’s Stand #D-130 in Hall 11 at the RAI Centre in Amsterdam.

The BMA CT allows for multi-array setups that can utilize a single low channel count DSP mixer as its onboard processing, its own acoustic echo cancellation, noise cancellation and beam selection – thus, per-beam processing isn’t needed and fewer DSP mixer resources are required. And, the array has a built-in power amplifier which allows each array to drive two 10-watt, 8-ohm loudspeakers.

The BMA CT also features ClearOne’s proprietary adaptive steering technology (think of it as smart switching). This provides room coverage while eliminating the need to adjust individual beams. Integrators can daisy chain ceiling tiles via P-Link (ClearOne’s proprietary peripheral link) for larger conference setups — for simpler wiring and longer distances compared to networked home-run connections. P-Link also allows integrators to daisy chain additional peripherals such as wireless mics, USB Expanders and GPIO Expanders. The system supports all of this functionality with zero consumption of analog I/O and signal processing in the DSP mixer leaving those resources available for other needs. With the ability to daisy chain up to three ceiling tile microphone arrays with a maximum of 650 feet (200 meters) between each array, a single low channel count CONVERGE Pro 2 mixer can support multiple rooms with a total cable reach of 1950 feet (600 meters).

ClearOne’s Pro Console software claims to simplify setup and thus eliminates the need for separate configuration and programming of switches, microphones, audio networks and DSP mixers. It also uses auto discovery to detect all connected BMA CTs and P-Link peripherals.

The BMA CT is available in three sizes: 24-inch, 600mm and 625mm, to fit common ceiling grid sizes. Featuring a white grille, the tile blends in with the look of a standard ceiling and becomes nearly invisible.

ClearOne’s beamforming microphone array technologies are protected by at least a dozen patents and pending patent applications. You can see them here.

The BMA CT will be shipping later this month to integrators and customers in the United States — and throughout the world shortly after. All the specs are here.
