Expand microphone coverage where a single integrated array is not enough. The AVer VB Series 20 m expansion microphone is designed for VB342 and VB342 Plus conferencing systems, giving meeting rooms additional pickup reach for participants seated farther from the main unit. This accessory is a practical fit for boardrooms, training rooms, and collaborative spaces where table length or room layout can leave voices outside the primary pickup zone. By placing the microphone closer to speakers, it helps preserve intelligibility and reduces the need for participants to lean toward the camera or main conferencing unit. For organizations standardizing on AVer VB series systems, this expansion microphone supports cleaner room design and more consistent audio capture across the table. It is the kind of accessory that matters when meeting quality depends on hearing every voice without asking people to repeat themselves.
