  • Page 5: Introduction

    20 or 30 years ago. The PLD Series amplifiers from QSC take it all a few steps further while adding such versatile features as digital signal pro- cessing, Flexible Amplifier Summing Technology™ (FAST), and particularly high power and channel density.

  • Page 6: Pld: A New Paradigm

    3 RU or 4 RU models. But imagine, with PLD you could now have those same eight channels of ampli- fication—with up to 2000 watts each—in only four rack spaces, with a total weight of only 44 pounds. QSC Audio Products LLC Application Engineering Team...
  • Page 7 Built-in processing An ample amount of digital signal processing (DSP) is built into the PLD Series amplifiers. The DSP serves a dual purpose: first is to manage the operation of the amp—by controlling the functions of the power supply, the protection systems, the fan speed, signal routing and mixing—and the second is to execute the necessary loudspeaker and system processing that...
  • Page 8 Physical layout The PLD Series feature a neat, organized layout of the rear panel connectors and master power switch. The four XLR inputs feature male loop-through connectors to allow easy daisy-chaining of input signals. There are six NL4 Speakon con- nectors, including two that are exclusively used for bridged mono operation, that offer connections for all possible individu- al, parallel, or bridged arrangements of amp channels.

  • Page 9: Electrical Power

    AC mains or from portable power—i.e., a generator. Power amplifiers are by far the biggest consumers of electri- cal power in an audio system, and through the PLD Series’s significant advances in power factor, efficiency, and universal voltage capability, the constraints presented by available power just aren’t as limiting any more. With PLD, your system can produce more audio power for a given amount of available AC, in more places and in more applications, than before possible.
  • Page 10 This practically eliminates any significant harmonic currents and voltage waveform distortion, and reduces current peaks as well. In its class of professional power amplifiers, only the PLD Series from QSC offers power factor correction in any models. QSC Audio Products LLC...
  • Page 11 Efficiency PLD Series power amps are kind to the AC mains in another important way: electrical efficiency, or the ratio of output power to the power drawn from the AC mains. The dynamic nature of audio and its frequency range spanning some ten octaves has always made it very difficult to achive very good efficiency in power amps.

  • Page 12: Fast (Flexible Amplifier Summing Technology™)

    You just can’t do this with any other amp. You can’t do this without QSC’s FAST, which keeps paralleled amp channels matched and synchronized precisely so they do not blow each other up when they’re connected together.

  • Page 14 Arranging four voltage sources in a combined series-parallel arrangement doubles both available voltage and current. In PLD amplifiers, this is suitable for harnessing the power of all four channels to drive high-power loads of 4 to 8Ω. QSC Audio Products LLC Application Engineering Team...

  • Page 15: Amplifier Navigator

    Amplifier Navigator™ QSC’s exclusive Amplifier Navigator™ software is a versatile utility for configuring, and managing PLD Series amplifiers. It connects to the amplifier via a USB cable (included with the amplifier); and with a USB hub, a single computer can connect to multiple (as many as 20) amplifiers at the same time.
