Overview

Advanced beamforming microphone array for grid ceilings with Dante

The BMA 360D features the industry's unique broadband, non-variable frequency polar pattern with uniform gain across all frequency bands.

FiBeam™ technology provides users with the highest level of natural and faithful audio transmission across all beams. Deep Sidelobe Beamforming, DsBeam™, provides over 40 dB of attenuation and virtually no sidelobes, resulting in superior reduction of reverberation and noise in challenging rooms for unparalleled audio clarity and intelligibility.

All beams can be individually tapped before processing via Direct-Outs via Dante. There is also a Smart Switched output which provides a fully processed sum on a separate Dante output. This uses the proven ClearOne DSP algorithms including echo suppression, noise reduction and level control.

The Dante input channels drive built-in power amplifiers. The amplifiers are configurable as 4 x 15 watts or 2 x 30 watts and offer flexibility for driving loudspeakers.

There is also the option for voice lift and camera tracking with the BMA360D.

Product Details

  • The BMA360D offers the industry's only ultra-wideband, frequency-independent beamforming microphone array technology with uniform gain across all frequency bands. With FiBeam™ and DsBeam™ technology, participants experience natural and faithful sound across all beams and within a single beam.
  • Deep Sidelobe Beamforming, DsBeam™, provides unparalleled attenuation of over 40 dB with no sidelobes, resulting in superior reduction of reverberation and noise, even in challenging rooms, for outstanding clarity and intelligibility.
  • With preset beam configurations for general room layouts or user-defined beam configurations for individual floor plans, combined with adaptive control, the BMA360D provides flawless coverage for all conference participants.
  • All beams can be made available on individual Dante channels prior to processing. The Smart Switched output is provided on a further Dante output, which provides a sum generated by the full range of ClearOne audio processors including echo cancellation, noise reduction and level control.
  • The Dante input channels feed the integrated power amplifiers with up to four audio signals. The amplifiers can be configured as 4 x 15 watts or 2 x 30 watts, providing flexibility to drive different speaker configurations.
  • The precision of the beamforming and adaptive steering technology enables the implementation of voice lifting and camera tracking.
