ESX VMA700.4 - 4-channel digital marine amplifier

In order to offer optimal sound on boats or other demanding locations, ESX has expanded its innovative amplifier range to include the  MARINE AUDIO  and now also offers two modern VISION Class D amplifiers to provide hobby captains who want to listen to better and more powerful music on the high seas with the power they need.
The prerequisite for marine suitability is certification in protection class IP67, i.e., the two robust amplifiers  VMA700.4  and  VMA700.4  are not only dustproof, but could even be temporarily submerged under water.
This means that the two VMA amplifiers are well protected even against adverse conditions on land, at sea, and in the air.
The often rather meager output of a radio with 10-15 watts per channel is hardly sufficient to drive a front and rear system. External amplifiers that provide significantly more power can help

. The sophisticated 4-channel power amplifier  VMA700.4.
Measuring just 11x25 cm, it is very compact despite its immense power of 175 watts RMS per channel, meaning it can always be found a suitable place, even in smaller boats.
All controls and crossovers are protected behind a screw-on cover.
