- Proprietary Plug&Play Power Supply Connector with safe-lock.
Hertz Advanced Class D architecture maximizes efficiency and power while minimizing heat and electromagnetic radiation – without penalizing sound quality! High-powered channels with bridging capability deliver the output levels needed in the marine environment.
Hi-Res certified performance, with an extended audio band up to 40 kHz.
Electronics components corrosion caused by exposure in wet environments is totally neutralized by the use of dedicated marinegrade (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.
This Hertz Marine product is IPX2 certified when installed with the cables facing down.
Designed to be the new reference, the Venezia line reaches an unmatched power/size ratio thanks to Hertz ADC (Advance D-Class), maximizing efficiency that reach 85% while enhancing sound quality that obtains the Hi-Res certification by JAS. Hertz ADC high efficiency design reduces battery consumption featuring a higher power than Class-AB traditional layout. ADC provides cleaner output to speaker system, especially when driving subwoofers.

BUILT-IN CROSSOVER FILTERS
Venezia amplifiers feature variable low/ high pass crossover filters, adjustable bass boost and a subsonic filter for an optimal tuning in every boat. The controls are protected by a polycarbonate panel located on the upper side, to be easily reached from above even after the product has been installed. When the system includes a processor like S8 DSP, the filter section can be totally excluded.
RUGGED ALUMINUM ALLOY HEAT SINK
Venezia amplifiers heat sink has been crafted from extruded aluminum, a material unmatched for lightness, robustness and heat dissipation. The oversized fin layout maximizes the surface area for optimal heat dissipation.
PLUG AND PLAY CONNECTION
The Safe-Lock Input, Output, and Power connections streamline installation and enhance durability in the field. Not availabe for compact models.
DESIGN TO LAST
The conformal coated PCBs provides superior protection against corrosion agents.
