The Huawei Mic 500 is a wired omnidirectional microphone array with a 6-meter pickup radius. For larger meeting rooms using the CloudLink Box 310 or 610, the system supports cascading to extend audio coverage. According to the hardware specifications, these terminals allow for a maximum of 2 Mic 500 units to be cascaded via the HD-AI audio input port. This configuration ensures that larger conference tables are fully covered without audio dead zones.
