QSC PLD4.3 4-Channel 2500W Processing Amplifier (Discontinued)

With four flexible channels of up to 1400 watts each, lightweight PowerLight universal power supply, DSP on-board for each channel, and all the right connectors, the QSC PLD4.3 Processing Amplifier is ideal for production and live sound applications.

The PLD4.3 consist 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 amplifier not only make your system perform better today, but also provide a wide and flexible range of options for future system growth.

THe PLD4.3 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 PLD4.3 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.

The PLD4.3 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.

The PLD4.3 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.
