Our KLR-4000 high-efficiency, high-power amplifiers are the ideal choice for high-output speaker systems, line arrays, dual 18” subwoofers and much more. If you think you need to use an expensive, European amplifier to get a clean, stable, quiet amplifier—think again.
KLRs are quiet, with signal-to-noise ratio ratings from >108 dB to >110 dB across all models. Each with a 3-position gain switch for both channels, a 3-position mode switch (bridged, stereo or parallel mono) and a 3-position 12dB/oct HPF switch (30Hz, 50Hz or off).
