The QSC 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.

The compact PLX2502 is 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.

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.

Additional mechanical touches such as the side stiffening rails, rear rack ears and cable tie anchor points attest to QSC's years of experience and attention to detail. QSC has even designed the integrated front handles so the amplifier slides into a rack without scraping the installers fingers on the rack sides. The exterior appearance of PLX2 amplifiers conveys what's inside - simply and truly, 21 pounds of the most advanced professional power amp on the planet.

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.
