The PLX1104 from QSC is a premium-quality, high-power amplifier designed for the most demanding live performance uses. Built on the third generation of QSC Power Light technology, the PLX1104 amplifier combines light weight, superlative audio quality and proven QSC reliability. With power ratings up to 550 watts, the PLX1104 amplifier is capable of providing plenty of clean, undistorted output to power-hungry speaker systems. Designed to power 1 or 2 speakers from each amplifier channel (4 ohm minimum loading), the PLX1104 model offers a simplified feature set while retaining genuine, uncompromised PLX performance and technology. Weighing just 13 pounds (5.9 kg) this “plug-and-play” amplifier is perfect for ultra-portable rigs, as well as reference-quality playback. PLX1104 audio power circuitry 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.Cooling design exhausts hot air out the front, keeping the rack cool
Flow-through heat sinks require no filters that could become clogged
Front panel LED power, clip, -10 dB, and signal present indicators for system monitoring and troubleshooting.
Speak on NL-4 output connectors provide a positive-locking speaker connection. Ch. 1 output uses all 4 wires for single cable connection to bi-amplified speakers
21-position front-panel gain controls for precise, repeatable amplifier adjustment
