With four flexible channels of up to 2000 watts each, lightweight PowerLight universal power supply, DSP on-board for each channel, and all the right connectors, the PLD4.5 is ideal for production and live sound applications.
Flexible Amplifier Summing Technology (FAST) drives most any loudspeaker system or configuration by distributing total amplifier power across one, two, three, or all four channels.
Four channels of full function onboard loudspeaker DSP with crossover and parametric EQ filters, limiting and alignment delay eliminate the need for outboard loudspeaker processors.
E Series Entertainment System DSP Tunings are now available for PLD processing amplifiers.
Powerful Intrinsic Correction processing maximizes the sonic performance of QSC loudspeakers.
20 factory preset configurations that can be modified and stored in the 50 user presets.
PowerLight universal switch mode power supply with PFC for highest efficiency, improved audio performance, and low weight.
Four input XLR connectors and six NL4 output connectors.
Integrated front panel with channel Select and Mute buttons, input and output LED metering, 400×240 LCD, intuitive navigation buttons, LED power button and indicator, and cast aluminum handles.
Preset Wizard simplifies amplifier configuration, providing selection from a list of the top selling passive loudspeakers.
