Offering three models, ranging in size from 2,500 to 8,000 watts, QSC Audio Products has unveiled the PowerLight 3 series of amplifiers. Offering a choice of DSP with remote control and monitoring via BASIS or analog input operation, the lightweight, 2RU lineup facilitates networked functionality or none at all. Each PowerLight 3 model offers high input voltage and selectable sensitivity, which can be adjusted via a series of rear panel switches with color-coded LED indicators. The 8,000-watt model, the PL380 combines a pair of 4,000-watt Class-D amplifier channels with the company’s PowerLight power supply to offer more than twice the audio horsepower of any previous 2RU PowerLight amplifier. Within the PL380 circuitry, reactive “back EMF” from the loudspeakers is recycled into the power supply to help promote an efficiency rating of 85%, according to the company. Models PL325 and PL340 share the same feature set as the PL380, albeit matched to upgraded versions of the company’s most advanced linear, Class H amplifier platform. Increased power supply capacitance in both amps is responsible for boosting 2-ohm power ratings to approximately 2,000 watts per channel in model PL340, and 1,250 watts per channel in the PL325. Price: PL380, $2,735; PL340, $1,633; and PL325, $1,253. For more information, contact QSC Audio Products at 800-854-4079 or at www.qscaudio.com.
