ESR2800D · Introduction 

Introduction

The ESR2800D is three-way, active control and amplification system specially designed for the KV2 Audio ESR full range
series loudspeaker systems. It houses all signal processing and amplification, as well as providing control and crossover
function for an external subwoofer cabinet if needed utilizing an external amplifier. The ESR2800D powers the ESR212. Each
unit incorporates six amplifiers consisting of two 100-watt, Class AB, push pull, low intermodulation amplifier for high
frequencies, two 200-watt, Class AB, push pull, low intermodulation design for mids and two 1000-watt, high-efficiency,
current- enhancing switch mode technology amplifiers for bass. The ESR2800D stereo configuration powers two ESR
cabinets accordingly.

ESR2800D - part number KVV 987 459 (250V)
