QSC PLX3102 Low-Z Power Amplifier; a premium quality, high-power amplifier that is specially designed for demanding live performance uses.

High-Power, Lightweight Professional Amplifier

Derived from the third generation of QSC’s own PowerLight technology and weighing in at just 21lb (9.5kg), the PLX3102 combines light weight portability, incredible audio quality and QSC reliability.

Rated up to 3,600 watts of power, the PLX3102 amplifier provides huge levels of clean, undistorted audio for the most power hungry of speaker systems.

Sleek, Lightweight Design

The sleek, lightweight design doesn’t just look great but it’s incredibly rugged and reliable too. The solid, cast-aluminium front panel has this amplifier looking great on your rack while acting as a support beam to keep your PLX3102 tough enough to take on all the rigours of the road.

User Focused Features and Design

Thanks to QSC’s years of experience and willingness to listen to their custom-base, the PLX3102 has many features that make its use more streamlined, simple and convenient.

Integrated handles on the front of the amplifier allows for easy sliding into any rack while side stiffening rails, cable tie anchor points and rear rack ears, further ensure that set up and use of the PLX3102 is a breeze.

High Efficiency Audio Circuitry

Replacing the usual huge and heavy AC transformer you’d expect an amp with this power to have, is a highly efficient, lighter-weight active design thanks to PowerLight switchmode technology.

While conventional AC transformers only provide 100 – 120 energy pulses per second, PowerLight supply offers 190,000 – 230,000 pulses per second. With such an increased level of pulses per second, it is much easier to deliver on-demand power to the amplifier’s output.

Consistent and efficient, the power supply will not “sag” so bass notes retain their full and powerful sound and the higher frequencies keep nice and clean.

Precision bias tracking makes tiny adjustments as the amplifier temperature changes, reducing crossover distortion thus delivering a more consistent sound and extremely clean high-frequencies, even when the amp is being driven hard.

The end result of the audio power circuitry’s work is the incredible performance level you’d normally expect from high end studio reference amplifiers.

Next Level Live Sound

Equipped with built-in subwoofer processing and delivering 600 Watts per side at 8 Ohms, the QSC PLX3102 is an awesome, lightweight rackmount stereo power amplifier that allows you to take your live sound performance to the next level.
