The MA5.2K is the latest addition to the renowned range of MA Series amplifiers. The MA5.2K utilises the Pulse Width Modulation principle in combination with a high efficiency two stage switching power supply to deliver true class D operation with unparalleled sonic performance and hitherto unobtainable power delivery. Occupying only 1U of rack space, weighing a mere 8kg (17.6lbs) and, with 2 x 2600 watts output into 4 ohms, the MA5.2K is a cost effective, high performance solution to many amplification requirements.
