The digital amplifier has become more compact and affordable than ever: with dimensions of only 190 x 35 x 112 mm, the three new ESX QUANTUM QM miniature amplifiers impress in all areas. The QM amplifiers offer cutting-edge technology in a very small space and are robustly built. All three amplifiers are based on their larger siblings from the ESX QL series, they are more compact and much easier to install. Thanks to the high-level inputs that include EPS and the auto turn-on function, they are ideal for integration into factory sound systems. Each model also features a compact bass level controller.
