Details
The Ashly KLR-4000 is a lightweight, high-performance amplifier incorporating the latest technologies and delivering quality and value at an affordable price. Whether your application is a professional audio or fixed performance installation, this 2-channel amplifier is optimized to provide reliable audio performance with sonic perfection and is perfectly suited for a wide range of sound reinforcement. The KLR-4000 amplifier is optimized to deliver high levels of sustained power, extraordinary audio performance, and road-proven reliability into 2, 4, or 8 Ohm loads and is housed in a uniform, rugged 2RU chassis.
This amplifier delivers a minimum power of 2,000 watts per channel into 2 ohm loads, 1,400 watts RMS per channel into 4 ohm loads, or 850 watts RMS per channel into 8 ohm loads with both channels operating. This amplifier has rear panel switching for parallel mono and bridging modes and when switched into bridged-mono mode, the amplifier delivers 4,000 watts into a 4 ohm load. The amplifiers protection includes output over-current, DC output, chassis temperature, and a mains circuit-breaker. The inputs include XLR, 1/4" TRS, and 3-pin Euroblock connectors and the outputs are four pin SpeakON type connectors. LED type indicators are employed to show the relative power level of each channel, clip/protect and power on/off.
