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.
