QE900.4

The award-winning ESX QUANTUM QE  series is in a class of its own. Conventional high-power digital amplifiers almost always cause interference in the vehicle and disrupt radio reception. Not so with the QE models: even during the development phase, special attention was paid to achieving emission-free playback. The sound is also just right, as high-quality components guarantee a first-class audiophile sound experience. The features are also impressive: automatic switch-on function, EPS®, variable filters – everything your heart desires is on board. High-quality connections and screw-mounted RCA sockets complete the perfect package. All QE amplifiers come with a sophisticated remote level control that can be installed with or without a housing to save space.
