Hertz ML POWER 4 four-channel power amplifier, high efficiency in Class AD

Hi-End performance with modern and advanced internal technology, the Mille series amplifiers are designed to further improve the already exceptional performance of the speakers of 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 used for the Mille Power line is extremely flexible and ensures that they can be used
with any configuration. Active crossovers have a 12 dB / oct. at 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 monitors 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 to avoid 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 top level system.

ML POWER features 4

1) ADC (ADVANCED D-CLASS TECHNOLOGY) ensures a high quality acoustic response with unmatched energy efficiency
2) Thermally optimized extruded heat sink with die-cast aluminum and ergonomic terminals
3) 250 W x 4 (2Ω) RMS power which boasts hi-end quality
4) 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
5) A / B specific input switch, eliminates the need for Y RCA adapters
6) ML Power IN with balanced speaker input for greater rejection noise and RCA
7) Operating status in real time with monitoring via 4 LEDs
8) Full-range and pre-out outputs also available with speaker inputs
9) ART (Auto Power Off Disabled)
