ESP Amplifiers
KV2 Audio ESP Amplifiers are concerned with providing the highest quality electronic amplification, based around purpose built circuitry and Topology, the lowest distortion levels and the fastest settling time, specifically to drive and control the KV2 Audio ESD passive range of Loudspeaker units to the highest definition and dynamic response.
Based around three ESP models, the range is presented in two and four unit-standard rackmount chassis, in two and four channel models, using bespoke Toroidal transformers, circuit design, amplifier and loudspeaker protection.
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.
Features
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).
Applications
Primarily designed to drive and control the ESD Cube loudspeaker system and ESD range speakers with superior sound quality.
