ESR2800D

Amplifier with Control & Diagnostics Tool

The ESR2800D is a 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 provides control and crossover function for an external subwoofer cabinet if needed utilizing an external amplifier. THE ESR28000D is now configurable via the front panel or remotely using KV2 Control & Diagnostics Tool.

The ESR2800D powers the ESR212. Each unit incorporates six amplifiers consisting of two 100-watt, Class AB, push-pull, low intermodulation amplifiers 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.

Features

  • The amplifier compliment inside the ESR2800D Amplifier is as follows:

  • High Frequency - 2x 100-watt, Class AB, push pull, low intermodulation design

  • Mid Frequency - 2x 200-watt, Class AB, push pull, low intermodulation design

  • Low Frequency - 2x 1000-watt, high-efficiency, current-enhancing switch mode

  • Configurable via the front panel or remotely using KV2 Control & Diagnostics Tool.
