2-Channel Class D Digital Amplifier

 The newly developed ESX QUANTUM QE series is a class of its own. Conventional high power digital amplifiers usually cause interferences in the vehicle and disturb the radio reception. Not so with the new QE models: During the development period, special attention was paid to achieve an emission-free music playback. Also the sound is perfect,  because high-quality components guarantee an audiophile sound experience at its best. The features are also impressive: Auto Turn-On Function, EPS, variable crossover filters – everything your heart desires is on board. High-quality connectors and screwed RCA sockets complete the perfect appearance. All amplifiers are delivered with a sophisticated level remote control, which can be installed very space-saving with or without housing.
