AUTO-MIXER SW

Product Overview Audio automatic switcher is a high-performance intelligent switching device designed specifically for switching audio signals. By working in conjunction with audio fault alarm devices, it can quickly diagnose audio source faults and switch signals in a timely manner when there is a problem with one audio source. This is beneficial for making clear judgments when encountering audio source problems, efficiently handling and solving problems, and achieving uninterrupted audio source signals. It can be widely used in speech engineering, audio-visual teaching, Command and control center, multimedia conference room and other occasions to complete the switching of audio signals.
