QSC PLD4.5 4-Channel 5000W Processing Amplifier (Discontinued)

QSC PLD4.5 4-Channel 5000W Processing Amplifier

The PLD4.5 consist of three powerful, lightweight, four-channel amplifier, each with onboard, advanced DSP and the capability to configure and combine channels in various ways to drive a wide range of loudspeaker systems. This amplifier not only make your system perform better today, but also provide a wide and flexible range of options for future system growth.

Flexible Amplifier Summing Technology (FAST)

PLD4.5 amplifier features Flexible Amplifier Summing Technology (FAST) that actively distributes the total amplifier power in various combinations across one, two, three, or all four outputs. This flexibility allows PLD4.5 amplifier to drive (for example) four full-range loudspeakers or subwoofers; a high-power subwoofer and a bi-amplified speaker; a single high-power full-range loudspeaker and subwoofer combo; or multiple power-hungry subwoofers from a single, very high output mono-block.

Advanced Amplifier Technology

The PLD4.5 amplifier uses QSC fourth generation class-D power amp design in combination with a custom power stage utilizing a new, purpose-built output device. These innovative MOSFET device provides high voltage operation without needing a full bridge output and offer superior audio quality due to co-location of the semiconductors.

System Processing

PLD4.5 is more than just an amplifier; it is also a capable and sophisticated loudspeaker processor. The close integration of processing and amplification allows the DSP to monitor and better respond to amplifier behavior, making dynamics processing far more accurate and effective than that typically achieved with separate components.

• 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.
• 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 switchmode power supply with PFC for highest effiency, improved audio performance, and low weight.
• Four Input XLR connectors, and six NL-4 Output connectors.
• Integrated front panel with channel Select and Mute buttons, Input and Output LED Metering, 400x240 LCD, intuitive navigation buttons, LED power button and indicator, and cast aluminum handles.
