We use MOSFET amplifier chips. Its a very mature solution used for 10 years. Sound is very clear and strong!The advantages of digital power amplifier. High efficiency -- Digital amplifier gain 90% efficiency , Analog amp only get 50%-70%. Strong load capacity and powerful amplifying.
Digital amplifier without amp feedback circuit to prevent Transient Inter Modulation Distortion. Analog amp with too many debug points, it's inconvenient for repairing and defectived easier. Digital amp with high integration, low defective. High sound reduction, precise and distinct of voice.
Big aluminium radiator with dual automatic variable-speed fans for smooth and quiet operation. The amplifier use Field Effect Transistor , 3300uf capacitance. Power circuit use 2200uf/200v capacitance.S/N ratio(A weighted): 100dB. Distortion(typlcal): less than 0.06%. Distortion(SMPTE): less than 0.05%. Input impedance: 10Kohms unbalanced 20Kohms balanced.
