It is suitable for medium and large theaters, outdoor performances, stadiums, nightclubs, entertainment venues, bars, banquet halls, concert halls and so on.


  • The latest class-Damplifier design has low distortion and high efficiency.
  • Switching power supply, with high efficiency; soft starter can prevent absorbing large currents into the power grid when starting up and interfering with other electrical devices.
  • Effectively suppress power harmonics, and meet the EU green power standard.
  • Intelligent peak clipper controls the power module and speaker system to work within a safe range.
  • Standard XLR + TRS1/4″ composite input interface, simple interface design is more convenient for different use
  • The amplifier has three options of input sensitivity, which can easily accept a wide range of signal source input.
  • Suitable for different places, stereo mode or bridge mode is optional.
  • Grounded input pin and suspension control switch can effectively suppress noise.
  • With overvoltage protection, under-voltage protection, over-temperature voltage limit, over-temperature shutdown, over current voltage limit, over current shutdown, DC protection, output short circuit protection, temperature control fan, amplifier frequency synchronization, PWM frequency synchronization, etc.
  • Built-in recoverable unique cut-off switch.
  • The dust-proof mesh of the panel is removable and washable.
