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
