Description
KLR High Performance Amplifier KLR-45000
Our KLR Series are high-efficiency, high-power 2-channel amplifiers that 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. They’re also versatile, 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).
Exceptionally lightweight for their class, all KLRs are designed in standard 2RU enclosures. Packed with features, KLRs make a great choice when you need to value engineer a distributed sound system.
