PRODUCT OVERVIEW
Liberty’s TU-USB-CEILINGMIC2 was designed for both recording and playback for interactive
classroom and remote teaching environments. A single USB Microphone will cover up to 8
meters of acoustic radius, while two USB microphones can fully cover a 120m2 classroom
or conference room. The teacher or main presenter can speak anywhere within 2-8 meters
from either omnidirectional microphone without aecting the microphone sound pickup.
Each microphone uses a large, professional-grade acoustic transducer to capture a wide
dynamic range and can pick up a rich, full-bodied sound. The unique enclosure design
eectively suppressed large space reverberation and can capture clear undistorted audio.
