Its on-device 3 TOPS NPU handles AI noise suppression and echo cancellation, and it runs without drivers with Zoom, Microsoft Teams, Google Meet and Webex. Link up to six units over Cat6 to cover rooms of 600+ sq ft. It suits huddle rooms, boardrooms and training rooms across Doha. Request a quote from SmartRooms Qatar.

What the Nearity A20S is

The Nearity A20S is a tabletop conference speakerphone for rooms where several people sit around one table and join video calls from a laptop. It connects to the computer over a single USB Type-C cable, so there is no driver installation and no separate audio interface to buy. Its eight omnidirectional MEMS microphones cover the full 360 degrees around the unit and pick up voices from up to 5 m (16 ft) away, so people do not need to lean toward the device to be heard.

Audio processing that does the hard work

All audio processing runs on the device itself, using a 4-core CPU and a 3 TOPS NPU, so the unit does not depend on a cloud service. The features that matter most in a busy room are:

AI noise suppression trained on more than 300 everyday office sounds, including keyboard typing, paper handling, mouse clicks and air-conditioning hum.
Echo control for both line echo and room echo, including reflections from glass walls.
Full-duplex audio, so two people can speak at the same time without the call cutting out.
Adaptive beamforming that steers pickup toward the active speaker, with automatic gain control keeping distant voices at a consistent level.

Speech is tuned for the 220 Hz to 12 kHz band. The built-in speaker is rated at 4 Ω / 5 W with a maximum output of 80 ± 3 dB SPL at 1 m. Audio parameters can be adjusted with Nearity Device Manager software, which also handles firmware updates.

Scaling from one table to a large room

A single A20S is rated for 100 to 250 sq ft and four to eight people. When a room grows, link up to six units into one cascaded array. The units connect through RJ45 ports labelled PREVIOUS (input) and NEXT (output) using PoE UTP Cat6 cable. The first unit takes the included DC 54 V / 1.2 A adapter, which powers every downstream unit, and extension units receive both audio and power over the same cable with no extra adapters. Six units are rated for more than 600 sq ft and 100 people.

Where it fits in Qatar

A four-person huddle room in an office tower in West Bay, where one unit handles weekly stand-ups with colleagues abroad.
A glass-walled boardroom in Msheireb, where echo from the glass and background hum are the main complaints from remote participants, and the echo and noise processing addresses both.
A training room in Education City with several units daisy-chained along a long table for hybrid seminars on Zoom or Microsoft Teams.

What to plan before you order

The A20S is designed for tabletop placement, so plan the seating layout first and measure the room before deciding how many units to order. The source data does not list an operating temperature range, so confirm the installation environment with the SmartRooms Qatar team before placing units near windows or in spaces that are not air-conditioned. The device supports Windows, macOS, ChromeOS and Linux, including Apple Silicon M1 to M6 and Intel-based MacBooks. The product carries a 12-month warranty from the manufacturer. Send your room sizes, seating plan and video platforms to the SmartRooms Qatar team, who will prepare a quotation usually within one working day for delivery across all eight municipalities of Qatar.

Questions about A20S

Who is the Nearity A20S designed for?

It suits small and medium meeting rooms, huddle spaces and training rooms where people sit around one table and join calls from a laptop. One unit is rated for 4 to 8 people across 100 to 250 sq ft, so it fits a huddle room in an office in The Pearl or a team room in Al Sadd. For larger rooms you can add units as the space grows, up to six in total.

How many people can one A20S cover in a room?

The data rates one unit for 4 to 8 people in 100 to 250 sq ft. Six daisy-chained units are rated for more than 600 sq ft and 100 people. A boardroom in Doha with a long table for 12 people would usually need more than one unit, and the SmartRooms Qatar team can confirm the layout during a free site survey before you order.

Does the A20S need drivers or software to start a call?

No. It uses plug and play over USB Type-C with the native USB Audio Class, so no driver or software is needed to start a meeting. Nearity Device Manager software is used for audio tuning, room-specific parameter changes and firmware updates. An IT team in Doha can set up several meeting rooms without installing anything on each laptop.

Which video platforms does the A20S work with?

Nearity lists Zoom, Microsoft Teams, Google Meet, Webex and GoTo Meeting as certified or verified platforms. It also works with Skype, Slack, BlueJeans, OBS and other standard USB audio applications. A school in Al Wakrah that uses Google Meet for parent evenings and Zoom for staff training can run both from the same speakerphone.

Is the A20S compatible with Mac and Chromebook?

Yes. The data lists Windows, macOS, ChromeOS and Linux, with support for Apple Silicon (M1 to M6) and Intel-based MacBooks and compatibility with the latest macOS versions. A consultancy that shares one meeting room between Windows and Mac laptops can move the same speakerphone between machines without changing hardware.

How does daisy-chaining work, and what cable do I need?

Link units through the RJ45 expansion ports, labelled PREVIOUS (input) and NEXT (output), using PoE UTP RJ45 Cat6 cable. The first unit takes the included DC 54 V / 1.2 A adapter and powers the rest, while extension units receive audio and power over the same cable with no extra adapters. Up to six units can form one cascaded array.

Will it pick up a presenter at the far end of a table?

The microphone array gives 360-degree coverage with an effective pickup range of 5 m (16 ft), and adaptive beamforming steers pickup toward the active talker. Automatic gain control keeps speech at a consistent level across that radius. A presenter at the far end of a long table in a training room in Education City can be heard without leaning forward.

Can it reduce keyboard noise and air-conditioning hum?

Yes. The AI noise suppression is trained to remove more than 300 common office noises, including keyboard typing, paper shuffling, mouse clicks and HVAC hum. In a Doha office where staff take notes during calls and the air conditioning runs constantly, this cuts the background noise that remote participants would otherwise hear. Echo cancellation also covers reflections from glass walls.

Is it suitable for hot or dusty areas such as a site office?

The data does not list an operating temperature range, and the unit is specified for tabletop placement only. Confirm the installation environment with the SmartRooms Qatar team before placing it in a site office, an unconditioned room or near a window in Mesaieed or Ras Laffan. For an air-conditioned meeting room, the team can check the setup during a free site survey.

Can I take it to client sites away from the office?

Yes. Alternative power is USB 5 V / 0.5 A, which runs a single unit directly from the host computer. The unit measures 120 × 120 × 64 mm and weighs 359 g (12.66 oz). A consultant presenting in a client office in Lusail can carry it in a bag and power it from a laptop, while the 54 V adapter is used for multi-unit setups.

What warranty comes with it, and how do I order?

The product carries a 12-month manufacturer warranty. To order, request a quote and share your room sizes and seating plan. SmartRooms Qatar usually sends a quotation within one working day. Purchase orders (LPOs) are accepted, and payment can be made by bank transfer, cheque or purchase order.
