QSC RMX 1850HD

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.
