Hertz ML POWER 4 Four-channel Class AD power amplifier

New product, never used and in perfect condition, only the packaging inside the box has been replaced.

Hi-End performance with modern and advanced internal technology, the Mille series amplifiers are designed to further improve the already exceptional performance of speakers in the same Mille series. The new ADC (ADVANCED D-CLASS TECHNOLOGY) ensures pure listening pleasure and unmatched energy efficiency while maintaining compact external dimensions to facilitate installation. The heat sink allows Mille Power amplifiers to work constantly at full power without overheating, further maximizing thermal efficiency.

ML POWER 4 versatility and control

The combination of filters adopted for the Mille Power line is extremely flexible and ensures that they can be used
with any configuration. The active crossovers feature a 12 dB / oct. to 24 dB / oct. adjustable slope plus Lo-Pass, Hi-Pass, Band-Pass and Full Range filters so as to adapt to every need.

LED STATUS DISPLAY controls the operating status in real time and highlights possible faults such as overheating, excessive loads on the outputs or short circuits on cables or speakers. This information allows the user to identify possible problems with the installation and take preventive action avoiding future damage. ML Power amplifiers have a speaker input (with noise reduction) for OEM units and an RCA input for aftermarket sources. ML POWER 4 (4 x 250 W 2 Ω) is the obvious choice for amplifying a front and rear Mille series entry-level system.

ML POWER 4 Features

  • ADC (ADVANCED D-CLASS TECHNOLOGY) ensures high-quality acoustic response with unmatched energy efficiency
