The QSC PLD4.5 is the flagship four-channel processing amplifier in the PLD Series, engineered for portable and touring sound reinforcement that demands high power plus onboard loudspeaker processing in a single 2RU box. It lets engineers drive multiple loudspeaker types from one amplifier while eliminating outboard processors.
Key Features
- Four independent channels with Flexible Amplifier Summing Technology (FAST) to distribute power across one to four outputs
- 1,200 W (8 ohm), 2,000 W (4 ohm) and 1,600 W (2 ohm) per channel; up to roughly 7,500 W total
- Full onboard DSP: crossovers, parametric EQ, limiting, alignment delay and Intrinsic Correction for QSC loudspeakers
- PowerLight supply with Power Factor Correction
- Four XLR inputs and six NL4 outputs, front LCD and LED metering
- 20 factory and 50 user presets
The PLD4.5 packs the power and processing of an entire amplifier rack into one lightweight chassis for demanding live rigs. Note: discontinued but widely available on the resale market.
