New HCP 4MDK features latest generation D-Class 2Ω stable output stage reaching the impressive power RMS of 150 W x 4 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), providing the ability to build a two zone stereo or a single zone stereo system with subwoofer. The dissipation system is optimized with the heat being transferred to the heat sink and then dissipated through the sides of the amplifier. HCP 4MDK four channels marine amplifier feature a compact design ready to face the open water environment, providing tons of clean power. The HCP M amplifiers crossover section ensure extreme flexibility: fully adjustable Lo-pass, Hi-pass filters with 12 dB/Oct. slopes and Bass Boost to enhance low frequencies.
