Hertz Venezia V4C (D class) marine power amplifier (4-channel).

Venezia V4C compact marine amplifier features an optimized power/size ratio boosting 110 W x 4 (4Ω) and 380 W x 2 (4Ω)! 
Hertz Advanced Class D technology maximizes efficiency and power while minimizing heat and electromagnetic radiation - enhancing sound quality that reaches new highs with Hi-Res certification! 
High-powered channels with bridging capability deliver the output levels needed in the marine environment. 

Venezia V4C is engineered and tested for marine applications (UV, salt-fog, vibrations, high/low temperature, thermal shock) and has obtained the IPX2 certification. 
The Safe-Lock Input, Output, and Power connections streamline installation and enhance durability in the field. 
The fanless convection cooling system is integrated into the cast heat-sink chassis. 
The balanced fully-differential input circuitry rejects electromagnetic noise and interference. 
The powerful and flexible preamp filter options are far beyond most mobile amplifier capabilities. 
Last but not least, Venezia V4C is fully protected by short-circuit, overload, and thermal protections - with auto-resetting.
