Technology

Hi-Res Audio certification featuring a frequency response of 10 Hz – 41 kHz.

Up to 85% efficiency thanks to ADC (Advanced D-Class) output stage.

Thanks to the built-in USS technology (Universal Speakers Simulator), DIECI POWER amplifiers can be correctly connected to head units with a "speaker load detection" function that monitors the presence of a low-impedance load to enable the audio outputs.

Cento Power amplifiers are ultra-compact to ensure effortless installations in the increasingly narrow spaces of modern vehicles or the factory amp area.
