Two shock mounted fans move air across the fins but never directly across the electronic components. This minimises maintenance cycles and improves the components lifespan and and reliability. <\/p>\n<p>The ESP4000 is housed in a professional 4U road rugged steel metal case with aluminium handles and evenly distributed weight.<\/p>\n<p><strong>Technical characteristics<\/strong>:<\/p>\n<p><strong>Features:<\/p>\n<p><\/strong><\/p>\n<ul>\n<li>Ultra high definition<\/li>\n<li>4 channel rack mountable power amplifier<\/li>\n<li>Specifically designed for optimised performance with ESD loudspeakers, as well as with other passive systems<\/li>\n<li>4 x 1000W \/ 2&Omega;<\/li>\n<li>Two separate power supplies ensure increased reliability and continuous delivery of full power<\/li>\n<li>Two shock mounted fans move air across the fins but never directly across the electronic components.
