GS-series Power Amplifiers

Tour series of professional high power amplifiers

Park Audio™


GS-series is a tour grade series of professional high power amplifiers,which completely covers the needs of companies in the sound reinforcement equipment for large concert halls, stadiums and large outdoor areas.
GS-series amplifiers have TD class topology, which almost uncompromisingly combines best features of switching and analog amplifiers. There are high efficiency of switching amplifiers and sound quality of analog amplifiers.
The amplifiers have individual power supply for each channel, which allows continuing working in case of failure one of them.
