ESR3000D

Amplifier with Control & Diagnostics Tool

The ESR3000D is a three-way, active control, and amplification system specially designed for the KV2 Audio ESR215 full-range series loudspeaker systems. It houses all signal processing and amplification, as well as provides control and crossover functions for an external subwoofer cabinet (utilizing an external amplifier). ESR3000D is now configurable via the front panel or remotely using KV2 Control & Diagnostics Tool.

The ESR3000D powers the ESR215MkII. 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 a 1000-watt, high-efficiency, current- enhancing switch mode technology amplifiers for bass. The ESR3000D stereo configuration powers two ESR cabinets accordingly.

Features

  • The amplifier complement inside the ESR3000D 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.

Applications

Specifically designed as the amplification and control elements for the ESR215 loudspeaker system in a 4RU mount module with Control & Diagnostics tool​
