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. -

Page 9: About Presets
About Presets The PLD amplifi ers are preset driven. In order to get the most out of the amplifi ers, an understanding of how presets work is essential. A Preset, in the context of the PLD amplifi ers, is a combination of amplifi er confi guration (inputs and outputs), DSP and loudspeaker assignments. When a preset is recalled it can change the output routing and wiring and/or any of the DSP settings. -
Page 10: Installation
Turn off the AC Mains disconnect switch prior to making any connections. The PLD amplifi ers have a Universal power supply 100 – 240 VAC, 50 – 60 Hz, with an IEC locking connector. -
Page 11: Connect The Audio Inputs
— Figure 12 — There are four female XLR connectors labeled 1 through 4 that provide the audio inputs to the PLD amplifi ers. A single input can be routed to one or a combination of outputs. You can use from one to four of the inputs. The inputs are 10 kΩ balanced or unbalanced, with a selectable sensitivity of either +4 or +14 dBu. - Page 12 WARNING!: When the AC Power is on, there is a potential of having dangerous voltage at the output terminals on the rear of the amplifi er. Use caution not to touch these contacts. Turn off the AC Mains disconnect switch prior to making any connections. IMPORTANT: QSC recommends that you connect jumpers where the terminals are the same points electrically.

- Page 24 Save the Preset After modifying the Inputs and Outputs for all channels, save the current settings as one of the 50 user-defi ned presets (U1: thru U50:). Each of the user presets, by default, is the same as factory preset F1: Confi g A B C D, so when you save the preset you are "overwriting" the preset currently in that numbered position.
