6.335,00 lei

The HMD8 DSP, powered by Hertz Marine DSP technology, rich new highs of listening pleasure during navigation. DSP user friendly PC-Software interface make the setup process a breeze, exploiting every single pills of performance from the installed speaker system. The amazing power of 8 * 85 W or 4 * 260 W (RMS@ 4Ω) gives the HMD 8DSP the capability to drive with authority the complete speaker system generating tons of crystal clear SPL up to 3 different zone of the vessel. “Power for the Waves” design philosophy features a sturdy enclosure made of extruded aluminum with an anti-corrosion treated PCB to ensure years of listening pleasure in open water.

PC-SOFTWARE

Hertz Navigator software allow to create pre-optimized software setup files for a specific boat model and the related audio system installed, ensuring a correct acoustic result in a very short time.

HMD8 DSP

ADVANCE D-CLASS

Thanks to the Hertz advanced D-CLASS output stage, HMD8 DSP joins maximum sound quality with unmatched efficiency to be very compact and easily installed in any position of the boat.

HMD8 DSP

CORROSION RESISTANT

Electronics components corrosion caused by exposure in wet environments is totally neutralized by the use of dedicated Marine grade (epoxy coated) PCB boards.

HMD8 DSP

SALT FOG PROOF

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.

HMD8 DSP

WATER JET TESTED

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.
