The PLX2 series is a range of premium quality, high-power amplifiers designed for the most demanding
live performance uses. Built on the third generation of QSC PowerLight™ technology, PLX2 amplifiers
combine light weight, superlative audio quality and proven QSC reliability. With power ratings up to
3,600 watts, PLX2 amplifiers are capable of providing plenty of clean, undistorted output to the most
power hungry speaker systems.
Two ways to get PLX2 performance,
The "02" models (PLX1802, PLX2502, PLX3102 and PLX3602) are the right choice for users who need to
drive up to four loudspeakers from each amplifier channel (2 ohm loading), or when extremely high power
bridge mono operation is required. These models feature built-in subwoofer processing, filter switches, and
front panel indications of bridge mono status.
The compact "04" models (PLX1104, PLX1804) bring the same performance and technology, plus even
greater value, to applications that don't require bridged or 2 ohm operation. Designed to power one or two
speakers from each amplifier channel (4 ohm minimum loading), these models offer a simplified feature set
while retaining genuine, uncompromised 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
PLX2 series amplifiers have the refined, rugged good looks usually associated with high performance
racing cars, competition bikes, professional power tools, and high power machinery. A solid, cast-aluminum
front panel adds professional style to any rack while also acting as an integral I-beam, rigidly tying the
chassis together for years of on-the-road reliability.
PowerLight switchmode technology replaces a large, heavy AC transformer (typically 20 lbs. / 9 kg) with a
highly efficient and lighter-weight active design. Conventional AC transformers provide 60 energy pulses per
second. The PowerLight supply delivers 100,000 pulses per second. More pulses make it easier to provide
on-demand power for the amplifier's output section. The power supply doesn't "sag" so bass notes stay full
and powerful while the high end remains crisp and clean.
PLX2 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.
