Hertz VENEZIA V5C, 5-channel Marine audio amplifier

INFORMACIJA

Hertz VENEZIA V5C - a compact 5-channel Marine class audio amplifier designed for use in boats, yachts, and other demanding environments. This model features advanced "Advanced Class D" technology, which ensures high efficiency, lower heat generation, and exceptionally high-quality sound with "Hi-Res Audio" certification. The amplifier delivers 80 W x 4 channels and 330 W for the subwoofer at 4 Ω impedance. The bridging function allows for connecting more powerful systems or an additional subwoofer. The integrated aluminum casing with passive cooling ensures stable operation even under heavy loads.

DESCRIPTION

Venezia V5C is the compact five channels marine amplifier, featuring 80 W x 4 (4Ω) plus 330 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 V5C 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 V5C is fully protected by short-circuit, overload, and thermal protections - with auto-resetting.

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.

KEY FEATURES

Engineered and tested for marine application (UV, salt-fog, vibrations, high/low temperature, thermal shock) featuring IPX2 certification.
ADC (Advanced D-Class) Technology 2Ω(1Ω for mono models) stable output stage providing Hi-Res certified audio performance with a superior efficiency.
Die-cast aluminum compact design with fan-less convection cooling system ensuring low operating temperature even at maximum power.
Balancedfully-differential input circuitry to reject electro-magnetic disturbances.
Bridge operation mode to drive a subwoofer or to create a powerful dual-mono system.
Built-in filter section protected by a polycarbonate panel suitable for any system configuration.
Short-circuit,overload and thermal protections with auto resetting.
Plug&Play Input and Output connections with safe-lock.
Proprietary Plug&Play Power Supply Connector with safe-lock.
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.

Technologies

ADC
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
Hi-Res certified performance, with an extended audio band up to 40 kHz.

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

SALT FOG TESTED
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.

WATER JET RESISTANT
This Hertz Marine amplifier is IPX2 certified when installed vertically with connections facing downward.
