QSC equipped the PLD amps with everything you need for the show, namely plenty of power and the ability to shape the sound to the room. This is accomplished through high-efficiency Class D amplifiers and an intricate series of DSP-powered processors. There's an impressive amount of features packed into just two rack spaces. And best of all, QSC set the PLD series up to be extremely user friendly. Plug it in and the front panel display leads you through the rest. No hassles, just awesome sound every time.
