GSd-series Power Amplifiers
Tour series of professional high power amplifiers with DSP engine
Park Audio™
GSd-series
GSd-series – is a tour grade two-channel power amplifiers with DSP processor.
GSd-series amplifiers are based on TD class topology. This topology almost uncompromising combines the best features of switching and analog amplifiers — high efficiency of switching and high-quality sound of analog amplifiers
The amplifier is equipped with a flexible and powerful high-end DSP from DFM audio, Germany, which provides high-quality signal processing, including FIR filtering. The NetControl software allows to control multiple amplifiers at the same time.
