ESP4000
Rack-mounted, High Definition Amplifier
The ESP4000 is an ultra-high definition 4-channel rack mountable power amplifier from KV2 Audio, specifically designed for optimised performance with ESD loudspeakers, as well as with other passive systems. For the ESP4000 all electronic circuit boards are first mounted on individual aluminum heat sinks, then on a secondary, internally sealed chassis, this leaves only the heatsink fins exposed. Two separate power supplies ensure increased reliability and continuous delivery of full power. 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 reliability. The ESP4000 is housed in a professional 4U road rugged steel metal case with aluminum handles and evenly distributed weight.
