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 Hertzaudio car amplifier ML Power 4 (4 x 250 W 2 Ω) is the obvious choice for a top level front-rear Mille system.

Input / Output

Technologies

ADVANCED D-CLASS TECHNOLOGY
Ensures pure listening pleasure while keeping a compact size with unmatched power efficiency.
LEDS STATUS DISPLAY
It monitors the amplifiers operating status in real time pointing out possible faults such as overheating, excessive loads on the outputs or short-circuits on cables or loudspeakers. This information allows the user to identify possible issues with the installation and to intervene before the amplifier goes into protection to prevent any damages.
HDP IN & ART(TM)
The ML Power IN module features a Speaker In input (with balanced circuitry minimizing noise) for OEM head units and an RCA IN input for aftermarket sources. When the Speaker In is used, the ART™ function (Automatic Remote Turn On-Off) is enabled, managing the amplifier remote turn on to avoid unpleasant “bumps”.
ADVANCED HEATSINK
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.
