1. 24 XLR inputs, LINE IN

2. 12 XLR outputs, LINE OUT

3. Connect the primary/backup processors to achieve synchronization of data between them Connectable processor models: DM48.20/DM24.12/DM20.4/MATRIX A6/MATRIX A12, the primary/backup devices should be of the same model

4. Detect the main and backup signal paths and equipment working status in order to achieve the main/backup switching function

5. Main/backup switching conditions:

-Open circuit in the main signal transmission path

-Main device MCU working status/DSP working status/abnormal input/output signal path

6. Primary/backup switching time:<0.5S, users should feel seamless switching

7. When the switch itself crashes or experiences power issues, it will default to switching from device output mode  

8. When monitoring abnormalities in the master or slave devices, the switch should have a buzzer alarm prompt function (the buzzer sound should not be too loud);

9. There should be no noise such as "POP" when switching between primary and backup

10. Size: RACK Width, Height: 3U

11. Dual AC power input, main/backup power switching
