128 MIC Network Ceiling Array Microphone

Sound reinforcement pickup radius is 3 m, video conference pickup radius is 5 m
8 audio collection areas, allowing you to adjust the areas and set area priorities to ensure sound collection
Support 48 kHz/24-bit high sampling rate, providing more authentic sound
Support intelligent noise reduction algorithms, effectively solving various transient noise interference in the environment
Support audio processing algorithms such as AEC, AFC, AGC, and EQ adjustment, and can support local amplification, remote conference, etc.
Support AES67 international standard transmission protocol (subsequent versions will support AES67 third-party compatibility), effectively ensuring low-latency and high-synchronization transmission for the network audio system
Support device activation, network setting, routing setting, parameter setting, and other related operations via audio assistant tool
Support 1-channel LINE IN/2-channel LINE OUT analog interfaces, which can be used with analog audio systems.
Support power supply and audio transmission via POE network cables, making installation and wiring more convenient
