Hertz Venezia Rules the Waves!
Hertz Marine Audio has launched a new range of amplifiers for marine applications. With some significant innovations, these amps are more compact and efficient than traditional marine amplifiers. We take a closer look!
There is a revolution going on in the world of marine. Many boats have carried audio systems in the past. Still, with more high-performance craft on the water, there is a need for more powerful amplifiers to drive multiple speakers to ensure music is carried tunefully to passenger’s ears.
Power is paramount in this world as most listening happens on deck, and if you thought a car was a noisy environment, you should try a boat!
Hertz Venezia can deal with it all, no matter how large or complex the system for your boat is. The range includes 1, 4, 5, and 6-channel amplifiers, including two that run on 24 volts.
All amplifiers in the range feature Hertz super-efficient ADC (Advanced D-Class) electronics. This technology allows the amplifiers to achieve up to 85% efficiency, which reduces the current drain on the battery even when playing loud.
The amplifiers carry Japan Audio Society (JAS) Hi-Res capability. This makes them audiophile quality, ensuring users get incredible definition and reproduction.
Hertz ADC electronics offers highly flexible configuration options as channels may be bridged to provide even greater power to fewer channels. For instance, the Venezia V6 can output 160 watts to each of six speakers with a 4-ohm impedance. However, in a 5-channel configuration, two channels can be bridged to provide a mighty 540 watts to a subwoofer. In 3-channel mode, each pair of outputs delivers 540 watts. Hertz ADC allows each channel to run into 2 ohms, offering more power. Each channel can output 290 watts into 2 ohms (1760 watts), although bridged channels will only run into 4 ohm loads.
A good deal of care is required when designing electronics to work in a watery environment. Added to this, salt water can prove highly corrosive to some materials. Each Venezia amplifier is compliant with IPX2 standards. This means they are protected against water and dust ingress. They are also designed to offer protection against UV, salt fog, vibrations, high/low temperature, and thermal shock.
A marine-grade epoxy coating is applied to the circuit board to ensure the amplifier will operate even after years of marine application use.
A cast aluminium chassis facilitates efficient cooling. Over-sized cooling fins ensure that the amplifier does not require forced air cooling. This, in turn, helps to keep the chassis compact. The V6 amplifier is just 330mm X 200mm X 54mm and weighs just 3.72 kg.
Several on-board filters are included for those not using a Hertz signal processor. These allow your installer to set crossover frequencies and filter out unwanted frequencies from specific speakers. These controls will often be tweaked in situ so they are top-mounted and protected by a polycarbonate cover.
Hi-pass, low-pass and band-pass 12dB/octave filters are all included. Adjustable bass boost and a subsonic filter are also provided, offering comprehensive set-up parameters. The filters are bypassed if the amplifiers are connected to a Hertz signal processor, such as the highly flexible Hertz S8.
Balanced differential inputs ensure any noise generated by other onboard equipment does not make it to the amplifying sections of the amplifiers.
