$649
Hertz HMP4D – D CLASS 4 CH AMPLIFIER
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 by passable 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.
TECHNOLOGIES
IP64 CERTIFICATION
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.
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.
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.
