AVer VC520 Pro Expansion Speakerphone and Microphone

The AVer VC520 Pro Expansion Speakerphone is intended to extend the microphone pickup range of the VC520 Pro Video Conferencing System and maximize audio coverage. The Expansion Speakerphone has full-duplex transmission with no sound clipping, allowing for seamless conversation in both directions. To improve speech intelligibility, the unit has a two-microphone array that takes up sounds equally around the room, as well as automated gain control, echo cancellation, and background noise reduction.
