Hertz Mille Power ML Power 1

Hertz Mille Power ML Power 1 - Mono Amplifier for High-Efficiency Subwoofers

The Hertz Mille Power ML Power 1 is a 1-channel amplifier that precisely drives Mille speakers and subwoofers. Its Advanced D-Class Technology (ADC) combines high efficiency with a compact design. A dual-technology heatsink ensures stable performance even during longer sessions. Thanks to flexible active crossovers, variable phase, and auto turn-on via high-level input, the ML Power 1 can be easily integrated into both factory and aftermarket systems.
