In order to be able to offer optimal sound on boats or other demanding locations, ESX has recently expanded its innovative amplifier range to include the MARINE AUDIO range and now also offers two modern VISION Class D amplifiers to provide the required performance to amateur captains who would like to hear better and more powerful music on the high seas. The prerequisite for marine suitability is certification in protection class IP67, i.e. the two robust amplifiers VMA700.4 and VMA700.1 are not only dustproof, but can even be submerged under water for a while. This means that the two VMA amplifiers are well protected even against adverse conditions on land, at water and in the air.
To drive a front and rear system, the often rather meager power of a radio with 10-15 watts per channel is hardly sufficient. External amplifiers that provide significantly more power can help. The noble 4-channel power amplifier VMA700.4 easily delivers more than 10 times as much. At just 11×25 cm, it is very compact despite the immense power of 175 watts RMS per channel and therefore always finds a suitable place even in smaller boats. All controls and crossovers are protected behind a screwed cover.
