Hertz Marine Venezia V5
Ch: 5 - 3 | 1700 W
Venezia V5 is the most-powerful five-channel Hertz marine amplifier ever, featuring 130 W x 4 (4Ω) plus 490 W (4Ω) for the subwoofer. 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 V5 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 preamp filter options are powerful and flexible. Last but not least, Venezia V5 is fully protected by short-circuit, overload, and thermal protections - with auto-resetting.
