Mille power amplifiers are born to fully enhance the outstanding performance of the Mille speakers. The new ADC (ADVANCED D-CLASS TECHNOLOGY) ensures pure listening pleasure while keeping a compact size with unmatched power efficiency. The heat sink, engineered with double technology, extrusion and aluminium die-casting, enables the Mille Power amplifiers to work constantly at full power without ever overheating, further maximizing thermal efficiency. The ultra-versatile Hertzaudio car amplifier ML Power 5 (100 W x 4 + 550 W 2 Ω) provides the ability to drive a Mille system including the subwoofer. The HRC BM (Hertz Remote Control Bass Management), low frequencies level remote control, is optional.
