PLX1802 Dual Channel Amplifier

Rugged, Reliable Power Amplifier

We all know reliability is the name of the game in power amps. Sound quality too. So, if you roll the two together and ask the QSC engineering team to pull it off, you can bet these experts in power amp technology will. The QSC PLX1802 is a perfect example of their work. This super-rugged, practically industrial-grade power amplifier does the job. It offers a high level of front-panel indication to keep you in touch with what’s going on, while smart additions like the 21-position gain controls let you precisely set (and repeat) your amplifier settings. Looking for a rugged power amplifier? Look no further than the QSC PLX1802.

QSC PLX1802 Low-Z Power Amplifier

575 Watts/Channel into 4 Ohms, 900 Watts/Channel into 2 Ohms

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.

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, 13 to 21 pounds of the most advanced professional power amp on the planet.

PowerLight switchmode technology replaces a large, heavy AC transformer (typically 20 pounds / 9 kg) with a highly efficient and lighter-weight active design. Conventional AC transformers provide 100 or 120 energy pulses per second, the PowerLight supply delivers 190,000 to 230,000 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
