Professional Audio Shop Established Since 1996
The KLR-4000 from Ashly is a professional-quality power amplifier that provides high-quality audio in a lightweight and efficient design. The amplifier has a 2RU rackmount design for installation in any equipment rack. It can operate in stereo, bridged, or parallel modes for terrific versatility. The 2-step Class-H circuitry provides excellent efficiency, while the switch mode power supply delivers deep bass, punchy midrange, and clear treble. The amplifier has Euroblock and combo XLR/TRS inputs, as well as Neutrik Speakon outputs, allowing you to connect to virtually any professional sound system.
The amplifier features front panel level controls for each channel, as well as indicator LEDs for output level, clip/protect, and power on/off. Each channel has a 3-position gain switch, as well as a 3-position high pass filter switch. A switchable limiter is also built in to prevent distortion. A forced air cooling system with front-to-rear air flow and removable dust filters prevents the amplifier components from overheating. Integrated protection circuitry prevents damage from over-current, DC output, and overheating.
