ML Power 4

D-CLASS FOUR CHANNEL AMPLIFIER

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.
