Amplifier - Rack mounted

The SL3000 Amplifier is a three-way, active control and amplification system specifically designed for the KV2 Audio SL Series modular loudspeaker systems. The SL3000 Stereo Amplifier drives and controls one SL412 per channel and follows the typical KV2 holistic approach of matching components with high-quality electronics for true direct performance. The SL3000 utilizes a 1000-watt high efficiency – current enhancing, switch–mode technology, with linear active filter design for the low mid-section, a 200-watt class AB push-pull low intermodulation design amplifier for the mid-range, and a similar 100-watt design for the high frequencies. It houses all time-alignment, phase correction, amplification, and equalization, as well as provides an external subwoofer crossover output to run further subwoofer cabinets if needed.


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

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

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


Specifically designed as the amplification and control elements for the SL loudspeaker systems in a 4RU mount module
