A built-in public RS232 interface can independently connect external high-definition video switcher and matrix;
The automatic closing time of each microphone can be set independently, and the maximum time can be set to 999 seconds to meet the needs of various applications;
It is equipped with 12 microphone outputs to facilitate independent recording, and a set of auxiliary inputs with 6.3 interfaces;
All Lotus data interfaces can directly drive 8-ohm headphones without amplifier;
Built-in multiple password management functions to effectively protect parameters from being modified;
The microphone status change has the code sending function, which can be opened or closed freely by the software, and the code sending interface can be customized;
Support the central control function, and set all system parameters through the bidirectional central control serial port;
The system has a perfect self-inspection function, which can judge general faults on site;
The system has a 2.23-inch dot-matrix display screen, which can set all system parameters;
