The MA18K is one of three models extending the range of the renowned MA Series power amplifiers. The MA18K 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 MA18K 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.
