ESP4000 · Introduction 

Introduction

The ESP4000 is a four channel rack mountable power amplifier. The unit contains four seperate 1000 watt amplifiers, two 
independent power supplies (two channels running off each power supply) signal paths, inputs and outputs as well as limiting 
and low frequency enhancement on each of the four channels within a four rack unit chassis. It can be used to power a range of 
passive loudspeakers as well as being specifically designed for optimised performance with KV2 Audio's ESD Series.

Whilst this unit is simple to operate improper use can be dangerous. This is a very highpowered device that can put out high 
voltages and sizeable currents. Always use safe operating techniques with the ESP4000.

FOR YOUR SAFETY, READ THE IMPORTANT PRECAUTIONS SECTION AS WELL AS THE INPUT, OUTPUT AND POWER 
CONNECTION SECTIONS OF THIS MANUAL.
