What area does the Nearity A40 cover?

The A40 covers an 8 m × 8 m area (26.2 ft × 26.2 ft) centred on the unit, using 8 deep-sidelobe beams from its 24 MEMS elements.

How many A40 units can be daisy-chained?

Up to 8 units daisy-chain over PoE on UTP CAT6, connected through the unit's two RJ45 Ethernet ports.

It runs AI noise suppression, full-duplex, echo cancellation, AGC, adaptive pickup beams and intelligent mixing, with 63 dB (A-weighted) SNR.
