BM80 Cascading Microphone Speaker<\/strong><\/h4>\n
    \n
  1. Supports cascading of up to 8 units via wired connection<\/span> (USB Type-C interface), suitable for small, medium, and large conference rooms.<\/span><\/li>\n
  2. 8-mic array with high-sensitivity, high signal-to-noise ratio (SNR) MEMS microphone units for clear long-distance pickup.<\/li>\n
  3. AI noise reduction, AI echo cancellation, and AI Automatic Gain Control (AGC) for superior noise suppression and full-duplex performance.<\/li>\n
  4. High microphone sampling rate, up to 32kHz in AI mode.<\/li>\n
  5. High-output, high-dynamic speaker driver for wider coverage and powerful sound.<\/li>\n
  6. Sleek, technological design that integrates seamlessly into corporate meeting rooms, combining quality and artistry.<\/li>\n
  7. Can connect to a computer or interactive flat panel via an included wireless Dongle.<\/li>\n<\/ol>\n
