De-reverberation to Make Your Voice Heard Clearly

The A20S is equipped with an 8-element beamforming mic array and a sophisticated AI algorithm that effectively eliminate acoustic and room echo, resulting in clear, equitable audio for meetings even in challenging environments.

All Sizes Meeting Room, One Form Factor

Amplify the size of your audio system by connecting up to 6 A20S units, ensuring that every voice is audible in any sized room. This allows you to customize the audio setup to fit your needs and provide the best sound quality.

Full-Duplex to Make Your Meeting Flow

The A20S conference speaker mic's full duplex communication and beamforming mic array allow multiple speakers to be heard simultaneously and clearly at both ends of the call without any missing words. This will enable you to focus on the voices without being distracted by background noise.

Deep-learning Al algorithm

The A20S uses an advanced deep-learning AI algorithm to reduce background noise and improve audio quality during meetings. This technology is particularly effective at eliminating non-stationary noise, such as the sound of typing or mouse clicks, to provide a clear and uninterrupted audio experience.

Clean Meetings, Clear Minds: Noise Reduction Technology

NEARITY's noise reduction technology uses deep learning algorithms to suppress background noises during meetings, resulting in clear and uninterrupted communication among participants. The technology has been trained on a large dataset of meetings to optimize its performance in reducing noise.

Compatible Platforms

Compatible with a wide range of video conferencing platforms, including Zoom, Skype, Slack, Google Hangouts/Classroom, GoToMeeting, BlueJeans, Twitch, Facebook Live, xsplit, OBS, etc.
