The A21S Nearity is a next-generation USB speakerphone designed for professional audio conferencing in meeting and conference rooms. It is equipped with 8 microphones for high-performance omnidirectional sound capture, with a range of 5 meters in all directions. Its new AI-based noise cancellation algorithm reduces over 300 types of sound interference, such as keyboard noise, footsteps, and air conditioning.
The Full-Duplex technology allows for natural and fluid conversations, enabling participants to speak and be heard simultaneously on both sides of the audio conference. The A21S also offers the possibility to chain multiple units via a PoE network cable, increasing the audio capture range and easily providing sound coverage for very large rooms. Up to 8 units can be chained and powered in this way.
Certified for the Zoom video conferencing platform, the A21S is also compatible with other software such as Microsoft Teams, Google Meet, Webex by Cisco, and GoTo Meeting. Its robust design and exceptional audio quality make it one of the most advanced high-end professional speakerphones on the video conferencing market.
