ESP1000 - Rack mounted, High Definition Amplifier

The ESP1000 is a four channel rack mountable power amplifier specifically designed for optimised performance with KV2 Audio's ESD Cube / ESD1.10 subwoofer system. The unit contains four separate 250 watt amplifiers, two independent power supplies (two channels running off each power supply), four signal paths, inputs and outputs as well as limiting and equalization for given passive loudspeaker / subwoofers. Six independent configurations are selectable and it can be used to power any ESD units and other ranges of passive loudspeakers.

The ESP1000 will mount in a standard 19" rack system. Integral rear mounting rack ears are also provided for additional support. It is important that you do not rely on fixing and mounting the ESP1000 using just the front panel as the support. Use eight screws and washers to mount the amplifier to the equipment rack rails, (four for the fronts and four for the rear).



Primarily designed to drive and control the ESD Cube loudspeaker system and ESD range speakers with superior sound quality.
