i-POWER 4000 is a highly reliable advanced CLASS-D power amplifier specially designed for low impedance load without overheating even in the most extreme conditions. At the same time it is capable of reproducing sound very tight with outstanding clarity and stability at 2 ohms load like never before possible with conventional amplifiers.  

  Specially designed for 2ohms load

  Unmatched power in a 2U chassis

  High dumping factor even when clipping

  Very stable output at any load
  Short circuit-able speaker outputs
  High quality connectors Neutrik
  AGC for over current protection
