The QSC PLD Series is designed representing the revolutionary advancement in amplifier innovation and technology. Specifically crafted for the needs of portable and production sound system users, PLD provides robust, extraordinary and robust high fidelity power to drive multiple configurations and channels of loudspeakers while, all with minimal operator complexity, simultaneously deploying sophisticated digital processing. The PLD Series is consisting of three lightweight, fourchannel, powerful amplifiers, each equipped with advanced, onboard DSP and the capability to combine and configure channels in various ways to drive a wide range of loudspeaker systems. These amplifiers also provides a flexible and wide rang, and more, it is making your system performance much better all the time. One of it is the QSC PLD4.2 with 2000W Amplifier using FAST channel combining technology. 4 channels, 500 watts/ch at 8Ω, 700 watts/ch at 4Ω, 625 watts/ch at 2Ω, with XLR and NL4 connectors. 

The QSC PLD4.2 is best for live sound and production applications, because it is equipped with DSP on-board for each channel, with four flexible channels of up to 700 watts each, lightweight PowerLight universal power supply, and all the right connectors.

Flexible Amplifier Summing Technology™ (FAST)

PLD amplifiers feature 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 PLD Series amplifiers 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

In combination with a custom power stage and with the PLD Series amplifiers uses QSC fourth generation class-D power amp design it is utilizing a new, purpose-built output device. Without the need a full bridge output, these innovative MOSFET devices are providing high voltage operation, and offering superior audio quality due to co-location of the semiconductors. Additionally PLD amps benefit from the roadproven and famed PowerLight power supply, greatly enhanced with Power Factor Correction (PFC) that aligns the current waveform with the AC mains voltage waveform. The PLD Series is being enabled by the PFC to draw current from the wall in a more controlled and efficient manner resulting in incredible power from a single standard AC breaker. In addition, the PLD Series amp also offer multi-stage sleep modes, it is saving energy when possible without ever compromising the performance. The result is an exceptionally flexible and powerful platform that offers low weight and outstanding efficiency.

System Processing

PLD Series 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. This synergistic approach employs both RMS and Peak Limiters that allow the combination of amplifier and loudspeaker to produce more output without being pushed to distortion or destruction. In addition to the dynamics processing, the onboard DSP offers four channels of crossover filters, parametric EQ, and alignment delay - everything needed to optimize a loudspeaker system. PLD amplifiers also offer Intrinsic Correction™, a combination of IIR and FIR Filtering and loudspeaker processing methodology first developed for our WideLine line array loudspeakers. Intrinsic Correction compensates for the non-linearities in loudspeaker array and horn design and results in notably superior performance from your QSC loudspeakers. 

Preset Wizardry

The on-board processing is managed and stored as presets, with 20 factory presets for the most common loudspeaker applications. For greater customization, the built-in Preset Wizard streamlines amplifier setup and provides loudspeaker selection from a list of top selling passive loudspeakers.

Space Efficient

With four channels of amplification plus drive rack signal processing in just 2RU, the PLD Series replaces equipment taking up as much as three times the rack-space. Simple to Use With a dedicated front panel UI complete with LED meters and indicators, a 400x240 TFT color display, a rotary encoder and ergonomic navigation buttons, PLD amplifiers provide an intuitive interface for the user to control the system. The simplicity of the PLD amps is further illustrated by the fact that a complete system can be set up in mere minutes.
