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.
