The VENEZIA V8 DSPx² 24V represents the most advanced expression of Hertz Marine audio engineering for vessels equipped with 24-volt electrical systems, designed to act as the intelligent heart of high-end and multi-zone onboard sound architectures. Combining exceptional power with advanced digital signal processing, it delivers precise control, immersive sound, and long-term reliability in real marine conditions. The integrated dual-core DSP and EVOCA® proprietary technology work together to optimize loudspeaker behavior in real time, enhancing dynamics, clarity, and listening comfort while protecting system components over time. Thanks to native A2B digital networking, VENEZIA V8 DSPx² 24V enables scalable system architectures with reduced wiring complexity, making it ideal for luxury yachts, OEM applications, and sophisticated installations where performance, efficiency, and integration matter. Certified for Hi-Res Audio and engineered with marine-grade materials, it ensures a refined, high-fidelity listening experience that remains consistent season after season, even in open-air environments.

Technologies

EVOCA is Hertz’s proprietary sound optimization technology that enhances loudspeaker behavior in real time. By modeling speaker dynamics, it improves control, clarity, and low-frequency performance while reducing distortion and mechanical stress, delivering a more immersive and reliable listening experience in marine environments.

 

Hi-Res

High-resolution processing at 24 bit / 96 kHz with an extended 10–42 kHz bandwidth preserves detail, dynamics, and spatial accuracy, delivering a refined and natural listening experience in marine environments.

 

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.

 

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.

 

bit Wave is the advanced Hertz software for configuring and tuning marine DSP systems. It offers intuitive control over signal routing and sound optimization, simplifying complex multi-zone setups while ensuring consistent, high-quality performance across every listening area.

 

A2B digital communication enables multiple units to be connected through a single cable, simplifying installation while maintaining full signal synchronization. Designed for luxury yachts and advanced multi-zone systems, it ensures clean, reliable performance with minimal wiring complexity.

 

CORROSION RESISTANT

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

 

WATER JET TESTED

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