BMA 360 Frequency-invariant lobe depth down to -40 dB

The industry's only ultra wideband, frequency invariant beamforming microphone array ceiling tile with uniform gain response across all frequency bands.

FiBeam™ technology gives users the ultimate in natural and full fidelity audio across all beams and within a single beam. Deep Sidelobe Beamforming, DsBeam™, provides unparalleled sidelobe depth, below -40 dB, resulting in superior rejection of reverb and noise in difficult spaces for unrivaled superb audio clarity and intelligibility.

Deep Sidelobe Beamforming, DsBeam™, provides unparalleled sidelobe depth, below -40 dB, resulting in superior rejection of reverb and noise in difficult spaces for superb audio clarity and intelligibility.
A dramatically new approach to precision beamforming provides a new beam topology to easily achieve distortion-free, full 360-degree coverage of any room shape and any seating arrangement using ClearOne Audio Intelligence™.
The BMA 360 Voice Lift feature provides a powerful and simple way to drive multiple mix-minus speaker zones allowing everyone in the conference room to hear every word.
Due to the exceptional performance of the breakthrough technologies, FiBeam and DsBeam, greater Voice Lift gains can be realized that have not been previously possible.
The combination of ClearOne’s beamforming and feedback cancellation technologies provide up to a 20 dB boost in gain before feedback compared to an omni mic.
The BMA 360 FiBeam and DsBeam technologies enable a 12 dB increase in gain before feedback compared to an omni mic.
Voice Lift is further enhanced with the patented DARE™ Feedback Eliminator, found on CONVERGE® Pro 2 DSP Mixers. This technology provides unsurpassed removal of feedback and ringing--giving an additional boost of up to 8 dB to the total system gain.
The amazing sound of FiBeam and DsBeam, combined with the superior CONVERGE Pro 2 Feedback Eliminator, creates the industry’s absolute best Voice Lift system provided by any ceiling mounted microphone, including beamforming microphone arrays.
Voice Lift can be configured on up to three BMA 360s per CP2.
Further advancements in adaptive steering (think of it as smart switching) provide impeccable coverage of each conference participant as well as simultaneous support for camera tracking and Voice Lift.
The BMA 360 can switch on as many as two beams at one time, which enables better pickup of local presenters that are speaking at the same time.
6G Acoustic Echo Cancellation (AEC) delivers unparalleled per-beam full-duplex audio performance. On-board audio algorithms, like noise reduction, filtering, and Automatic Level Control, eliminate the need for per-beam processing in a DSP mixer - requiring fewer DSP mixer resources.
Built-in, robust power amplifiers, configurable as 4 x 15 Watt or 2 x 30 Watt, provide flexibility for driving loudspeakers.
ClearOne’s breakthrough technologies, FiBeam, DsBeam, Voice Lift, and 6G AEC combine to create VividVoice™, a significant advancement for professional audio and video conferencing.
Integrated features significantly reduce system design complexity, simplify installation, consume less rack space, and lower system cost.
Daisy-chain up to three ceiling tiles via P-Link for divisible rooms or larger conference setups – for simpler wiring and longer distances compared to networked “home run” connections via Ethernet.
Single workflow for configuration using CONSOLE® AI software. Competing products require practitioners to program multiple components using different toolsets: Ethernet switches, Ceiling Tiles, DSP mixers, and the Dante Controller.
To help ensure the very best possible design of a ClearOne Voice Lift system, a BMA 360 Voice Lift Design Guide, a BMA 360 PAG/NAG calculator, and a BMA 360 DARE Configuration Guide are available from clearone.com.
Supports three different ceiling grid types: 24 in, 600 mm, and 625 mm. It incorporates a VESA-mount hole pattern that supports pole mounting. Hard-ceiling mount adapter kits are also available.
