Compact conference microphone for meeting rooms

The Poly Studio A2 is a wired desktop microphone designed for conference rooms and meeting spaces. Its four microphone elements capture speech with a sensitivity of -35dB and a signal-to-noise ratio of 68dB, focusing on the active speaker for natural remote audio. The compact black unit measures 92 mm by 92 mm by 24 mm and weighs 120 grams, fitting unobtrusively on a table.

Scalable audio coverage for extended sessions

Up to eight microphones can be connected in series to extend coverage across large rooms without complex configuration. The device operates reliably between 0 and 40 °C with relative humidity from 15 to 80 percent, making it suitable for sustained daily use in typical office environments. A single AAAA battery is required for operation.

Versatile mounting and sustainable construction

The microphone includes a mounting plate and I/O cable for flexible placement and tidy cable management. Its housing uses at least 60 percent recycled plastic and ships in paper-based packaging. The package dimensions are 168 mm by 140 mm by 67 mm with a weight of 470 grams. Storage conditions span -40 to 70 °C and 5 to 95 percent humidity.

Questions about this item

Does the 120 g Poly Studio A2 microphone generate noticeable heat or fan noise during all-day meetings?

The unit has no fan and operates silently within 0 – 40 °C, so it adds no audible noise or perceptible warmth to the room.

What host device and cable does the B22X6AA#AC3 need to function?

It connects by wire to a Poly Studio video bar or compatible conferencing system; the required I/O cable and mounting plate are included in the box.

Can I daisy-chain this microphone with older Poly table mics I already own?

Only Poly Studio A2 desktop microphones can be series-connected — up to eight units — so legacy models cannot share the same chain.
