Overview of Grandstream GMD1208
The Grandstream GMD1208 is a desktop wireless extension microphone that increases the overall audio coverage of Grandstream conferencing systems such as the GVC3220. Its 8 omni-directional microphones use dynamic beamforming to choose from up to 24 beam directions, covering 360-degree full-band voice pickup within a 5-meter radius. Ultrasound pairing, proprietary 2.4G/Bluetooth dual mode, error-resilient transmission and a 1500mAh battery with up to 12 hours of talk time bring mobility and flexibility to any meeting. A multi-functional touch key with LED status indication makes it an easy choice for large meeting rooms, boardrooms and training rooms in offices, hotels and schools.
