INPUTS  
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.
