[DISCONTINUED] QSC PLD4.5 4-Channel 8000W Power Amplifier

The QSC PLD Series represents a revolutionary advancement in amplifier technology and innovation. Designed specifically for the needs of portable and production sound system users, PLD provides efficient, robust and extraordinarily high fidelity power to drive multiple channels and configurations of loudspeakers while simultaneously deploying sophisticated digital processing - all with minimal operator complexity. The PLD Series consists of three powerful, lightweight, four channel amplifiers, each with onboard, advanced DSP and the capability to configure and combine channels in various ways to drive a wide range of loudspeaker systems. These amplifiers not only make your system perform better today, but also provide a wide and flexible range of options for future system growth.

QSC PLD4.5 Features

• 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 switch mode power supply with PFC for highest efficiency, improved audio performance, and low weight.
• Four input XLR connectors and six NL4 output connectors.
