A new range of amplifiers
Hertz Marine Audio have launched a new range of amplifiers for marine applications. With some significant innovations, these amps are more compact and efficient than traditional marine amplifiers.
There is a revolution going on in the marine world. Many boats have carried audio systems in the past; however, with more high-performance craft on the water, there is a need for more powerful amplifiers to drive multiple speakers to ensure that music is carried tunefully to passengers’ ears.
Power is paramount
Power is of paramount importance in delivering high-quality sound, not just high volume levels, as good-quality sound can cut through a noisy environment. The aim with the Hertz Venezia is to tackle these issues head on, regardless of how large or complex the system on board a craft may be. The range includes one-, four-, five- and six-channel amplifiers, including two that run on 24 volts.
All amplifiers in the range feature Hertz’s super-efficient ADC (Advanced D-Class) electronics.
Advanced Electronics
All amplifiers in the range feature Hertz’s 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. The amplifiers carry Japan Audio Society (JAS) Hi-Res capability, which means they boast audiophile quality, ensuring that users get incredible definition and reproduction.
Flexible configuration
Hertz’s ADC electronics offers highly flexible configuration options as channels may be bridged to provide even greater power to fewer channels. For instance, the Hertz Venezia V6 can output 160 watts to each of six speakers with a 4-ohm impedance. However, in a five-channel configuration, two channels can be bridged to provide a mighty 540 watts to a subwoofer. In three-channel mode, each pair of outputs delivers 540 watts. Hertz ADC allows each channel to run into 2 ohms, thus offering more power. Each channel can output 290 watts into 2 ohms (1760 watts), although bridged channels will only run into 4-ohm loads.
The V6 amplifier measures just 330mm x 200mm x 54mm and weighs a mere 3.72kg.
Salt water consideration
A good deal of care is required when designing electronics to work in a watery environment. Salt water can also prove highly corrosive to some materials; therefore, each Hertz 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 temperatures and thermal shock. The circuit board is also coated with marine-grade epoxy to ensure that the amplifier will operate even after years of use.
Efficient cooling
A cast aluminium chassis facilitates efficient cooling. Oversized cooling fins ensure that the amplifier does not require forced air cooling. This, in turn, helps to keep the chassis compact.
Measurements & Weight
The V6 amplifier measures just 330mm x 200mm x 54mm and weighs a mere 3.72kg.
Balanced differential
Balanced differential inputs ensure that any noise generated by other on-board equipment does not reach the amplifier’s amplifying sections.
Each channel can output 290 watts into 2 ohms (1760 watts), although bridged channels will only run into 4-ohm loads.
Hertz are striving hard for durable, flexible audiophile quality and it would appear that the Hertz Venezia series marks an exciting development in this complex and ever-growing sector of the audio systems market.
