The amplifier provides flawless lows, punchy mids and pristine highs, delivering extraordinary audio performance, and proven reliability into 2, 4,or 8 Ohm loads. The amplifier is optimized to deliver high levels of sustained power. This is due to the switch mode power supply with extensive protection circuitry, offering stable output voltage and minimizing wasted energy. The forced-air cooled variable speed fan, provides a regulated front to rear air flow. The KLR-4000 is quiet, though, with a signal-to-noise ratio of 109 decibel at 8 Ohms. It has a gain switch for both channels and a 12dB/oct High Pass filter switch (30Hz, 50Hz or off). Also, it is equipped with an on/off limiter switch and a mode switch for bridged, stereo or parallel mono. LEDs on the front panel indicate the relative power level of each channel, clip/protect and power on/off. Lastly, the KLR-4000 is easy to clean, thanks to removable dust filters. Does your project need an affordable, clean, stable, quiet amplifier, choose KLR-4000!
