El software Hertz Navigator permite crear archivos de configuración de software previamente optimizados para un modelo de embarcación específico y el sistema de audio relacionado instalado, asegurando un resultado acústico correcto en muy poco tiempo.
Gracias a la avanzada etapa de salida D-CLASS de Hertz, el DSP HMD8 se une a la máxima calidad de sonido con una eficiencia inigualable para ser muy compacto y fácil de instalar en cualquier posición de la embarcación.
Electronics components corrosion caused by exposure in wet environments is totally neutralized by the use of dedicated Marine grade (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 defines all the Hertz Marine products as totally protected against water jets of different entities, making them highly performant in the marine environment.
