AVer COMFON540 Full-Duplex Microphone Array Speakerphone

Product Overview

The AVer FONE540 is a full-duplex USB conferencing speakerphone built for personal workspaces, huddle rooms, and medium-to-large conference rooms. Two omnidirectional microphones deliver 360-degree pickup with advanced noise suppression and full-duplex echo cancellation, so remote participants hear every voice clearly without feedback or dropped words. The unit connects via USB or Bluetooth and integrates with every major video conferencing platform including Zoom, Microsoft Teams, Cisco Webex, and Google Meet. Daisy-chain expansion allows up to three additional FONE540 units or up to four microphones to cover larger tables and irregularly shaped rooms.

Product Description

The AVer FONE540 microphone array speakerphone addresses one of the most persistent problems in hybrid meetings: audio that forces people to repeat themselves. Full-duplex operation means both sides of a call can speak simultaneously without either signal being suppressed — a critical advantage over half-duplex systems that cut off one talker when another begins. AVer's double-talk detection technology pairs with advanced noise suppression to filter out keyboard typing, HVAC noise, dogs barking, and construction sounds, leaving only voice audio on the conference line.

The two built-in omnidirectional microphones capture voice from every seat around the table with 360-degree pickup. Speaker output reaches 90 dB SPL at 0.5 meters, sufficient for a standard conference room without additional amplification. A 3.5 mm line-in jack lets a smartphone or non-USB device join the call through the FONE540 as a BYOD bridge, merging phone audio with the USB session into a single conference for all participants.

Touch controls on the top surface manage volume, mute, call, and hang-up functions without fumbling through software menus. Smart LED indicators display speakerphone status at a glance so everyone in the room knows whether the line is live or muted. The FONE540 is Zoom certified and ships with a 16-foot (5 m) Micro USB cable and a 3-foot (0.9 m) 3.5 mm aux cable. It carries a 2-year warranty on the speakerphone unit and 1 year on accessories.
