Designed for professional live performance and portable rigs, it features front-exhaust cooling, Speakon NL-4 connectors, and QSC’s proprietary bias tracking technology for consistent, distortion-free audio quality. ## Description The QSC PLX1804 power amplifier is part of QSC's PLX Series -- a range of premium-quality, high-power amplifiers designed for the most demanding live performance uses. Built on the third generation of QSC Power Light technology, PLX1804 amplifiers combine light weight, superlative audio quality and proven QSC reliability. The compact PLX1804 brings the same performance and technology of the PLX "02" models to applications that don't require bridged or 2 ohm operation. Designed to power 1 or 2 speakers from each amplifier channel (4 ohm minimum loading), this models offer a simplified feature set while retaining genuine, uncompromising PLX performance and technology. Weighing just 13 pounds (5.9 kg), these "plug-and-play" amplifiers are perfect for ultra-portable rigs, as well as reference-quality playback. The audio power circuitry inside the PLX1804 achieves performance normally associated with studio reference amplifiers. In order to reduce crossover distortion, precision bias tracking makes minute adjustments as amplifier temperature changes. The benefit is cleaner high-frequency and more consistent sound no matter how hard the amplifier is driven. The higher power models use QSC-exclusive class H output circuitry, a form of audio "turbocharging" that increases maximum power without affecting the basic audio quality.
