Ashly's KLR-Series amplifiers are high-efficiency lightweight two-channel high Live Sound > Amplifiers > Power Amplifiers incorporating the latest technologies delivering quality and value for professional performance at an extremely affordable price. Whether your application is professional audio or fixed performance installation KLR amplifiers are optimized to provide reliable audio performance with sonic perfection.
Covering a power range from 1000 to 2500 watts per channel at 2 ohms (20Hz-20kHz 1% THD) the KLR-2000 KLR-3200 KLR-4000 and KLR-5000 are perfectly suited for a wide range of sound reinforcement. All four KLR amplifiers are optimized to deliver high levels of sustained power extraordinary audio performance and road-proven reliability into 2 4 or 8 ohm loads and are housed in a a uniform rugged 2RU chassis. Each KLR amplifier uses a state-of-the-art Switch Mode Power Supply which assures you of flawless lows punchy mids and pristine highs. The output topography of the KLR-2000 is Class-AB while the KLR-3200 KLR-4000 and KLR-5000 are a two-step Class-H design. KLR-Series protection circuits include: output over-current protection DC output protection chassis internal temperature monitoring inrush limiting and a mains circuit breaker.Front panel features include: individual input attenuators signal clip and protect LEDs air inflow vents with removable dust filters power switch and power LED. Rear panel features include: balanced inputs via 3-pin Euroblock combo XLR/ 1/4" TRS connectors Neutrik Speakon output connectors 3-position gain switch (32dB 26dB or 1V input sensitivity) 3-position mode switch (bridged stereo or parallel mono) 3-position HPF switch (30Hz 50Hz or off) on/off limiter switch air outflow vents and permanently attached power cord.
