Hertz ML POWER 4 Four-Channel Class AD Power Amplifier

Hi-End performance with modern and advanced internal technology, the Mille series amplifiers are born to further improve the already exceptional performance of speakers from 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 to adapt to any need.

LED STATUS DISPLAY monitors operational status in real time and highlights possible faults such as overheating, excessive loads on outputs or short circuits on cables or speakers. This information allows the user to identify possible problems with the installation and intervene preventively avoiding future damage. ML Power amplifiers feature 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 first-level Mille series system front and rear.

ML POWER 4 Features

  • ADC (ADVANCED D-CLASS TECHNOLOGY) ensures high-quality acoustic response with unmatched energy efficiency
  • Thermally optimized extruded heat sink with die-cast aluminum and ergonomic terminals
  • 250 W x 4 (2Ω) of RMS power that boasts hi-end quality
  • 12 dB / oct. continuously adjustable (from 50 to 5k Hz and from 80 to 3.3k Hz) active crossover with Lo-Pass / Hi-Pass or Full Range settings
  • Specific A / B input switch, eliminates the need for RCA Y adapters
  • ML Power IN with balanced speaker input for greater noise rejection and RCA
  • Real-time operating status with monitoring via 4 LEDs
  • Full-range outputs and pre-out available also with speaker inputs
  • ART (Automatic Remote Turn-off)
