產品特色

適合應用

  • 視訊會議
  • 音訊會議
  • 需規劃分區收音需求的會議

ClearOne 將 FiBeam 和 DsBeam 技術運用在 BMA 360 麥克風陣列上。 FiBeam 技術使 BMA 360 成為可提供自然和全保真的聲音。 DsBeam 技術可出色地抑制混響和噪音能力,並提供音訊超群的清晰度和清晰度。。

每個 BMA 360 最多可以有四個 Voice Lift 區域,以提供一種簡單直觀的方式來驅動多個揚聲器組。 內置四通道功率擴大機使接線快速,內置功率放大器和混合減區的組合使 Voice Lift 功能易於創建和部署。

麥克風需要搭配ClearOne 數位處理器使用
