Hertz Marine Venezia V1 24V
The Venezia V1 24V is the most powerful mono Hertz marine amplifier in the range, rated at 1260 W at 1 ohm stable. Hertz Advanced Class D technology maximises efficiency and power whilst minimising heat and electromagnetic radiation. The amplifier is engineered and tested for marine conditions — UV, salt-fog, vibrations, high and low temperatures, and thermal shock — and holds IPX2 certification. Safe-Lock input, output, and power connections aid installation and long-term durability. The fanless convection cooling system is integrated into the die-cast aluminium heat-sink chassis. Balanced fully-differential input circuitry rejects electromagnetic noise. Powerful and flexible preamp filter options are included. Auto-resetting short-circuit, overload, and thermal protections are built in as standard.

About the Hertz VENEZIA V1 24V
From our tech experts at CEN
A marine amplifier, rated at 1260w RMS, coated and sealed against damp and salt air, and built for 24V systems.
Who it suits
Boats, ribs and commercial craft, plus open builds where an amplifier will get damp. The 24V design suits larger vessels running that system voltage.
Our tech experts advise
Mount it ventilated and as dry as the vessel allows, and fuse the feed at the battery. Marine installs want tinned cable and sealed joints throughout. get in touch and we will talk through mounting, wiring and power for your boat.
