CA2L - Professional Power Amplifier


Professional Power Amplifier

CA series is the amplifier with big power and excellent performance. It can meet different audio avenues. 


  • Big power,dynamic energy;
  • Innovative heat sink structure and high quality heat sink fan assure reliable working for a long time;
  • Loading impedance temperature-power-running voltage" can be controlled alternately, Speed of Fan is automatic adjusted by temperature. When load is too low or temperature is too high, the equipment can adjust the power supply and lower impedance of power, which improves sound quality and protect the equipment better. The reliability will be improved remarkably;
  • Low distortion;
  • High slew speed, outstanding sound quality and high transparent;
  • Low noise:S/N>108dB(A Weight);
  • 20Hz~20KHz <+0/-0.25 dB;wide frequency band;
  • Small dimension, 2U rack mounting.
  • CA2L is specially designed for low loading imedance, and can work for a long time under 2Ω.
