Extend room audio where fixed microphones fall short. Yealink VCM36 W is a wireless expansion microphone designed for Yealink A20 and A30 meeting systems, giving distributed participants a cleaner path into the conversation. Its 360° pickup pattern captures speech from across the table, while Optima HD Voice full-duplex processing helps keep natural back-and-forth intact instead of clipping voices mid-sentence. For conference rooms that need flexibility, the wireless design reduces cable constraints and makes placement easier during room changes or temporary setups. Echo cancellation helps preserve intelligibility in shared spaces, and the capacitive mute touchpad gives users a direct, tactile control point at the table. With up to 65 feet of distance between the VC terminal and the microphone, it supports larger room layouts without forcing the system into a fixed seating plan. The 2,450 mAh battery is built for long workdays, delivering up to 24 hours of talk time and up to 14 days of standby. For organizations standardizing on Yealink room endpoints, VCM36 W adds coverage and control without changing the core meeting platform.
