TA-2500/ TA-2700/ TA-21200 Professional Power Amplifier


  • Industrial modeling aluminum panel, durable design, removable and washable dust-proof mesh and cooling vents.
  • Soft starter can prevent absorbing large currents into the power grid when starting up and interfering with other electrical devices.
  • Intelligent forced heat dissipation design, low fan noise, high dissipation efficiency, etc.
  • Built-in intelligent limiter controls the power module and the speaker system to work in a safe range.
  • Built-in 30Hz/50Hz high-pass filter.
  • Multiple modes: stereo, bridge, parallel.
  • Abundant reserve power, with 2R low-impedance output, high-fidelity and perfect sound quality.
  • High quality transformer, low resistance and large capacity electrolytic filter, make large dynamic work smooth.
  • Class-H efficient amplified circuit, comprehensive and reliable security protection measures and working status indicator (short circuit, overload, DC and overheat protection, transformer overheat protection).
