Proel's Research and Development Centre has developed the first Proel ¡°switching¡± power amplifiers: the PSWseries. Innovative switching power supply circuitry, and excellent performance of a class H linear power amplifier that precisely reproduces a signal, represent the two pillars of the PSW series. The design layout puts in evidence a structure ready to withstand any mechanical stress due to live touring sound reinforcement. The reduced weight, thanks to the new power supply stage, guarantees the best power/weight ratio. The low frequency response is immediate even for the most dynamic signals; this guarantees high level perfomance under any condition. The two models offered, PSW1800 and PSW2600 differ for the power outputs, but both are equipped with the same features.
