The QSC PLD4.2 is the entry model in the PLD Series of four-channel processing amplifiers, pairing flexible amplification with full onboard loudspeaker DSP in a 2RU chassis. It is built for portable and touring sound reinforcement that needs to power multiple loudspeaker types from a single amplifier without outboard processors.
