1, improve the protection circuit: the temperature is too high, the input signal is too large, the load is too heavy, the protection circuit is activated, sound and light alarm is issued at the same time improve the cooling fan speed.
2, balanced input: balanced input can increase the signal transmission distance and improve anti-interference ability of transmission.
3, priority signal input and control: Users can short cut or DC24V strong cut way, the device forcibly switch to the priority signal input emergency broadcast, and at the same time three or four strong cut to the control port.
4, Gain adjustment: The user can adjust the input gain
5, backup power supply system: When the AC power fails, the backup power supply system allows the device to continue to work.
6, comes with timing switch system.
