The add-on microphone with plug-and-play connection. Logitech expansion mic for MeetUp provides greater flexibility in huddle room configurations. MeetUps built-in beamforming mics are optimized for up to 8 feet (2.4m). To extend that range up to 14ft (4.2m), add an expansion mic. So whether people are seated at a table, sitting against the wall or standing, expansion mic for MeetUp means everyone will be heard. A microphone mute button lets those at the far end of the table mute the entire speakerphone system. The indicator light shows when the microphone is muted, when a call is active, and when Bluetooth® wireless pairing has begun.
