2.2 Four-channel audio input module
Four-channel audio input module is a TCP/IP based full-digital analog-to-digital signal processor. Local programs,
background music and internal voice signals can be transferred to this PA system via the local audio input port,
realizing seamless combination with traditional internal communication systems and intelligent control, without
needs for local operations. The module can work properly as long as it has been properly set by a management
software. It integrates a voltage limiter to ensure the speech transmission index is not reduced. No local operation
is required.
