Thanks to the ultra-compact cast-aluminium chassis (IP64 rated), the HMP 4D amplifier is nature-proof, being the ideal choice for UTV/ATV/motorcycle installations. It features an incredible power/size ratio and an easy setup thanks to the integrated crossover filter. The Front End section features a complete and bypassable crossover system, providing full system design flexibility with or without external processors, offering the user endless connection possibilities with any source. Inputs feature a special balanced circuitry, ensuring high rejection against electro-magnetic interferences, for noise-free results.
- Water Jet Tested: 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.
- Corrosion protection: Electronics components corrosion caused by exposure in wet environments is totally neutralized by the use of dedicated marine grade (epoxy coated) PCB boards.
- Salt fog tested: 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.
