Overview
lnputs: HCP 5MD marine amplifier feature a compact design ready to face the open water environment, providing tons of clean power. The 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.
More specifically HCP 5MD is suitable for a five channels system with subwoofer, a tree channel front + sub system using the front and rear built-in filters that also include a bass boost circuit and a subsonic filter.
