HCP 4M four channels  marine amplifier feature a compact design ready to face the open water environment, providing tons of clean power. The HCP M heat sink has been crafted from extruded aluminium, a material unmatched for lightness, robustness and heat dissipation. To keep size to a minimum, the power transistors are placed between the PCB and the top side of the heat sink where heat is gathered. Built up heat is then directed to the special dissipation “wings” along the side of the amplifier. Both Pre-In and Speaker-In inputs feature a special balanced circuitry, ensuring high rejection against electro-magnetic interferences for noise-free results.

The HCP M amplifiers crossover section ensure extreme flexibility: fully adjustable Lo-pass, Hi-pass filters with 12 dB/Oct. and 24 dB/Oct. slopes according to the amplifier model; Bass Boost is also available to enhance low frequencies. The HCP 4 M fourchannel model features also an extended frequency range filter, which can be used when designing active 2-way speaker systems.

Input / Output



Power supply featuring multiple winding transformer, Low-ESR 105°C capacitors, D-Class 2 Ω stable output stage.


Electronics components corrosion caused by exposure in wet environments is totally neutralized by the use of dedicated marinegrade (epoxy coated) PCB boards.


To satisfy the standards required by ASTM-B117, Hertz Marine products are tested with massive salt fog spray to ensure a complete resistance to corrosion, typical of this atmospheric agent.


The protection grade IP64 define all the Hertz Marine products as totally protected against water jets of different entities, making them highly performant in the marine environment.
