Thanks to the Hertz advanced D-CLASS output stage, HMD1 joins maximum sound quality with unmatched efficiency to be very compact and easily installed in any position of the boat.
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 define all the Hertz Marine products as totally protected against water jets of different entities, making them highly performant in the marine environment.
