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, the sound and light alarm is issued while increasing the speed of the cooling fan instead.
2, priority signal input control: Users can short cut or DC24V strong cut, the device forcibly switch to the priority signal input emergency broadcast.
3, multi-function input adjustment: provide CD, AUX, TEL and 2 microphone input, the total volume control, with high and low pitch adjustment and output level indication.
4, priority mute function: with priority input control authority. When the MIC1, TEL, with homophonic or siren sound input, according to the user set the mute level MIC2, CD, AUX mute control.
5, zoning control: Provides 5-way zoning channel, respectively, to select five zones and a healthy region to choose a healthy implementation of district and district control.
6, backup power supply system: When the AC power fails, the backup power supply system allows the device to continue to work.
