The PA series is an ideal choice for various applications, including the conΩference room, the report hall, the banquet hall, the stadium, and so on.
The warning function of machine abnormal work protection is: when the input signal is too large, t♦he load is too heavy, and the line is short, the corresponding indicator light is lit a→nd prompted, which has high reliability.


Perfect temperature protection: high current and high speed fan, low noise and good h₹eat dissipation. When the machine temperature rises, the temperature protection circui♣t will start the fan, and the speed of the fan will increase automatically w≥ith the increase of temperature.
There are two types of power supply, AC, DC, intelligent automatic switching; DC as a standby power  supply; when AC power outages or failure power, the power aΩmplifier will automatically cut into the DC power su©pply.
In line with the trend of environmental protection a nd energy saving, product design is a static standby power saving function, static ±standby power consumption less than 5W. When there is ∑no signal input, the machine waits for about 120S t​o enter the energy saving standby state and trigger immediately when there is a sign™al.
This machine is equipped with the switch machine squelch function, eliminating the power s×witch caused by.
120W * 2CH can do 240W output: Channel 1 gain knob switch set ON☆ (gain knob can adjust state), channel 2 gain knob switch set OFF, connect output of channel 1λ and input of channel 2, connect COM and COM of two channels at load output side, 100V and 100V  connection.
