The QSC PLD4.3 is a four-channel processing amplifier from the PLD Series, combining high-density amplification with full onboard loudspeaker DSP in a 2RU chassis. Aimed at portable and touring sound reinforcement, it drives several loudspeaker types from one amplifier and removes the need for separate outboard processors.
