Introduction
Built for system integrators, the PLD series amplifi ers provide multi-channel amplifi cation with built-in DSP and enough power to drive wide varieties
of speaker systems with optimal energy effi ciency. The PLD Series consists of three light-weight, 2RU, four-channel amplifi ers with on-board DSP and
fl exible channel combining. These amplifi ers not only provide the power and processing to make your system perform better, they offer outstanding
effi ciency ensuring that energy costs are kept to a minimum over the life of the installation.
PLD amplifi ers feature Flexible Amplifi er Summing Technology (FAST). Depending on the model, 1600, 2500, or 5000 Watts of total power can be
distributed across one to four outputs.
The PLD Series amplifi ers use QSC’s third-generation class-D power-amplifi er design in combination with a custom power stage utilizing a new output
device. In addition, PLD amplifi ers employ the proven PowerLight power supply in conjunction with Power Factor Correction (PFC) which aligns the
current waveform with the AC mains voltage waveform. PFC enables the PLD Series amplifi ers to draw current from the wall in a more effi cient and
controlled manner resulting in very high power from a single standard AC breaker. Additionally, the PLD Series amplifi ers offer multi-stage sleep
modes saving energy when possible without sacrifi cing performance. The result is an exceptionally powerful and fl exible platform that offers low
weight and effi ciency.
With four channels of amplifi cation plus signal processing in just 2RUs, the PLD series replaces equipment taking up as much as three times
the rack-space.
A single PLD Series amplifi er is a capable and sophisticated loudspeaker processor. Integration of processing and amplifi cation means that the DSP
knows exactly what the amplifi er is doing so dynamics processing can be far more accurate and effective. This approach employs both RMS and Peak
Limiters that allow the amplifi er and loudspeaker to produce more output without being pushed to distortion or destruction.
The on-board DSP offers four channels of crossover fi lters, 5-band parametric EQ/Low-shelf/High-shelf, alignment delay and dynamics processing
— everything needed to optimize a loudspeaker system. Additionally when using QSC loudspeakers, PLD amplifi ers provide Intrinsic Correction™, a
combination of fi ltering, limiting and loudspeaker knowhow that was fi rst developed for QSC's WideLine line-array loudspeakers. Intrinsic Correction
compensates for the non-linearity in array and horn design resulting in exceptional performance.
The PLD also includes manufacturers' recommended tunings for the most popular passive loudspeakers. A system setup wizard helps you select the
right preset, or select one of the 20 confi guration templates and create tunings that you can save in the user preset library.
With a dedicated front panel user interface, complete with LED meters and indicators, a 400 x 240 TFT color display, a rotary encoder and navigation
buttons, the PLD amplifi ers provide an intuitive means to control the system.
Unpacking
There are no special unpacking instructions. You may want to keep the shipping material for the unlikely event that the amplifi er should need
returning for service.
