The Nearity A21S is a USB conference speakerphone with eight MEMS microphones picking up voices up to 5 m (16.5 ft) around a 360-degree arc. Its AI 2.0 algorithms cancel echo, reverberation and noise, and Zoom certification lets teams use the touch mute and call buttons inside Zoom Rooms. It suits medium and large meeting rooms, where up to eight units can be daisy-chained over PoE.
A USB speakerphone for Zoom Rooms and other meeting platforms
The Nearity A21S is a USB conference speakerphone that combines an eight-microphone array, a full-duplex speaker and AI 2.0 audio processing in a single unit that sits on the meeting table. It is officially certified for Zoom, so the touch mute and call buttons on the unit can control the microphone and calls directly inside Zoom Rooms. The product is also listed for Microsoft Teams, Google Meet, Webex and GoTo Meeting, which suits organisations that use more than one platform.
Pickup and noise control for rooms with hard surfaces
Eight omnidirectional MEMS microphones capture voices across a 360-degree arc with a pickup range of up to 5 m (16.5 ft). Automatic gain control balances levels so that a participant at the far end of a long table is heard at a similar volume to someone seated beside the unit. The AI 2.0 echo, reverberation and noise suppression targets the problems common in glass-walled rooms, where sound reflects off surfaces and keyboard clicks or air-conditioning noise can reach remote callers.
The speaker is rated at 5W with a frequency response of 150Hz to 16kHz, which is enough for clear voices on calls and for playing back remote participants at a comfortable level in a small room.
Daisy chaining for boardrooms and lecture spaces
When a single unit cannot reach every seat, the A21S can be daisy-chained. The data lists up to four units connected with PoE cables and up to eight units when a PoE injector is used, so a large boardroom or training room can be covered without changing the platform or the computer. Each package ships with a USB cable, an Ethernet cable, an adapter and a user manual. The unit measures 64 x 120 x 120 mm and weighs 554 g.
Where the A21S fits in Qatar
- Government boardroom in West Bay: a leadership team joins video calls with colleagues abroad from a table where one unit covers the seats near the centre and a chained unit covers the far end.
- University seminar room in Education City: a hybrid session where the presenter and remote panellists need clear audio in a room with glass walls.
- Private school in Al Rayyan: a staff meeting room where teachers discuss in Arabic and English during a call with the head office.
- Hotel meeting room near Hamad International Airport: a mobile sales team that moves between rooms and needs a light unit it can carry from room to room.
What to plan before you order
Start by counting the seats and measuring the table, then decide between one unit and a chain. If you plan a chain, check that the room has a network point for each PoE connection and confirm that the laptop or PC can take the USB connection. SmartRooms Qatar offers free site surveys, so the team can check table layout and cable routes before installation. Government and school buyers can issue an LPO or quote against a tender reference.
