The MA12K is one of three models extending the range of the
renowned MA Series power amplifiers. The MA12K utilises the Pulse
Width Modulation principal in combination with a high efficiency two
stage switching power supply to deliver true class D operation with
unparalled sonic performance and hitherto unobtainable power delivery.
The MA12K operates at an astonishing 95% efficiency virtually
regardless of output power, occupies only 1U of rack space and is a
mere 12Kg (26.5lbs) in weight.
