Product Description

The Nearity A21S is a Zoom-certified USB-C conference speakermic with an 8-microphone 360° array, AI noise reduction, and PoE daisy-chaining. It delivers crystal-clear two-way audio for everything from huddle rooms to large boardrooms — and scales to bigger spaces by linking multiple units on a single SKU.

Key Features

  • 8 omnidirectional MEMS microphone array with 360° pickup up to 5 m (16.5 ft), covering rooms up to 560 ft² (50 m²).
  • 5 W full-range Hi-Fi speaker (150 Hz–16 kHz) for clear, room-filling sound.
  • AI 2.0 noise reduction — acoustic echo cancellation, de-reverberation, and background-noise suppression, plus full-duplex audio and Automatic Gain Control (AGC).
  • USB-C plug-and-play + PoE, with PoE daisy-chain up to 4 units (up to 8 with a PoE injector) to cover larger rooms — one SKU scales from small to large spaces.
  • Zoom Certified; works with Microsoft Teams, Google Meet, Webex, GoTo Meeting, and Skype.
  • Driver-free on Windows, macOS, Linux, and ChromeOS (also iOS and Android).
