1: Overload Protection: When the power amplifier is overloaded, it automatically reduces the output power to protect the loudspeaker and prevent the on-site audience from being startled.
2: Howl Protection: When the loudspeaker howls, it automatically reduces the output power to protect the loudspeaker and prevent the on-site audience from being startled.
3: Low-Impedance Protection: When the power amplifier encounters an ultra-low impedance load, it automatically adjusts the output power to maintain good on-site sound quality.
4: Short-Circuit Protection: When the output terminal is short-circuited, it automatically shuts off the input signal with no power output to prevent line fires.
5: Overheating Protection: When the power amplifier overheats, it automatically reduces the output power without shutting down, ensuring uninterrupted on-site music.
6: Intelligent Air Cooling: The fan features stepless speed regulation, automatically adjusting according to the internal temperature. This keeps the on-site environment quiet and comfortable, reduces dust intake, and extends the service life of the power amplifier.
7: Intelligent Muting: When there is no signal input, it automatically cuts off the noise from the pre-stage circuit, improves the system signal-to-noise ratio, and maintains on-site silence without current noise.
8: Volume Recovery: After the power amplifier protection is released, it automatically restores to the original volume to ensure sufficient on-site sound pressure level.
9: Shutdown & Restart: Automatically restarts after shutting down due to excessive power supply overload, ensuring the normal operation of the on-site system.
10: Power-On Volume Control: When the power amplifier is turned on, the volume automatically increases gradually from low to high without impact, protecting the loudspeaker and preventing the on-site audience from being startled.
11: Power-On Protection: After a low-current soft-start, it automatically detects the entire circuit without impact, protecting the loudspeaker and preventing the on-site audience from being startled.
12: Shutdown Protection: When shutting down, it automatically cuts off the output load circuit first without impact, protecting the loudspeaker and preventing the on-site audience from being startled.
13: Square Wave Protection: When the pre-stage inputs a sine wave signal but the post-stage outputs a square wave, it automatically reduces the input signal to eliminate square wave output, protecting the loudspeaker.
14: DC Protection: The pre-stage input is isolated from DC, and midpoint drift is automatically detected to ensure DC output is less than 3V, protecting the loudspeaker from damage.
15: Overvoltage Protection: Automatically shuts down when the input power supply is below 160V or above 260V, and automatically turns on to resume operation when the power supply voltage returns to normal.
