Logitech Expansion Mic for MeetUp provides greater flexibility in huddle room configurations. MeetUp's built-in beamforming mics are optimised for up to 2.4 metres (8 feet). Adding an Expansion Mic extends that range up to 4.2 metres (14 feet). So whether people are seated at a table, sitting against the wall or standing, Expansion Mic for MeetUp means everyone is heard. In addition, the indicator light shows when the microphone is muted, when a call is active and when Bluetooth wireless pairing has begun.
