DOLSI AT Series are digital power amplifier with Class D circuit category, a new milestone in amplfier development. PFC ( Power Factor Correction) technology is used in AT series . So the amplifiers can work well in power supply range ~90-260V. Advanced Class D PCB module and SMPS power supply module are used to obtain high efficiency and stability. It has very high power density, which makes the amplifier to reach powerful output in a very small shell space.
