BMA CT

The BMA CT is a patented ceiling tile beamforming microphone array that blends in perfectly with today’s drop ceilings. Built-in acoustic echo cancellation, noise cancellation, and beam selection eliminate the need for per-beam processing in a DSP mixer - requiring fewer DSP mixer resources.

Enhance Your Cloud Collaboration

Integrated features can significantly reduce system design complexity, simplify installation, consume less rack space, and lower cost.

Key Highlights

  • Single workflow for configuration using Pro Console® software. No need to program separate components: Ethernet switch, BMA CT, Dante® controller, and DSP mixer.
  • Daisy-chain up to three ceiling tiles via P-Link for larger conference setups – for simpler wiring and longer distances compared to networked “home run” connections.
  • ClearOne’s BMA technology is protected by at least a dozen patents and pending patent applications.
  • Each ceiling tile microphone array supports long distance P-Link mode with 200 m / 650 ft between tiles, for a total cable reach of 600 m / 1950 ft
  • Supports three different ceiling grid types: 24-inch, 600 mm, and 625 mm; as well as hard-ceiling mounts.
  • It’s all about the ClearOne architecture!
  • Built-in 2 x 10 Watt into 8-ohm power amplifier conveniently drives loudspeakers.
  • Adaptive steering (think of it as smart switching) - no need to adjust individual beams - for impeccable room coverage.
