This module is mainly used for voice intercom and can be equipped with (external) video conference terminals or other types of intercom hosts. The module has one audio input and one audio output, and its unique speech processing technology ensures high-definition calling for users.
The module can provide microphone signals that are closer to human voice for two-way voice intercom, and has the functions of eliminating echoes and noise in voice intercom, effectively eliminating steady-state background noise generated by air conditioning and projectors. True full duplex audio enables simultaneous speaking and listening. There is no need to switch between listening and speaking during the intercom process, nor will it affect the coherence of the conference voice. The automatic noise level balancing function can effectively suppress room environmental noise and system thermal noise, and improve the overall clarity of audio signals.
