HCP 4DK Ch: 4 - 3 - 2 | 2000 W

The new HCP 4DK features latest generation D-Class 2Ω stable output stage reaching the impressive max power of 2000 W with the excellent S/N ratio of 105 dB. Extremely versatile, complete in its functions, provided with Speaker-In and RCA-In inputs to work with any head units, it has been designed to work also in mono (selectable mode), for a three-channel system with sub and front, or a powerful two-channels system. All the Hertz Compact Power amplifiers are assembled with high-quality components and feature a complete and by-passable crossover system. The dissipation system is optimized with the heat being transferred to the heat sink and then dissipated through the sides of the amplifier.

LATEST GENERATION D-CLASS

The new HCP 4DK features latest generation D-Class 2Ω stable output stage reaching the impressive max power of 2000 W with the excellent S/N ratio of 105 dB.

HCP 4DK
REFINED HEATSINK WITH HIGH CONVECTION CAPABILITY

The extruded aluminum heatsink provides high efficiency thermal performance; using the top side of the heatsink to effectively dissipate the heat generated by the electronic components. The internal temperature remains constant at all power levels.

HCP 4DK
COMPLETED FILTER SECTION

Large array of filters customized for each model, to achieve maximum versatility: Lo-Pass, Hi-Pass, Band-Pass, Full Range, Bass Boost, Phase and Mono.
