About this item
Written by Crutchfield's Dominic DeVito
For road dogs and sonic svengalis QSC's PLD Series amplifiers make perfect companions on the road or in the studio - they're tough, powerful, versatile, and won't weigh down your tour van or equipment rack. Not only do these amps deliver plenty of clean, robust power, they also pack a wealth of technological advantages to help get your sound dialed in perfectly. PLD Series amps offer onboard speaker digital signal processing, so you can optimize your PA without adding another piece of gear. And the experts at QSC designed these amps to perform under critical energy-intensive conditions, so you can be sure every note comes out cleanly from start to finish of your gig or recording session. The color LED screen helps you utilize built-in crossovers, delays, EQs, and more. Firepower and flexibility The QSC PLD4.2 amplifier delivers an impressive 400 watts RMS by 4 channels at either 4 or 8 ohms, 800 watts by 2 channels, and 1600 watts in single-channel mode. It's also stable down to 2 ohms in 2-channel mode, and even down to 1 ohm in single-channel operation. QSC's proprietary MOSFET output devices combine with Class-D power to make this amp run with remarkable efficiency, so power demands are reduced and controlled. On the front panel, the amp offers LEDs (including limiter, clipping, and signal), select, and mute buttons for each channel, plus a master control knob and four menu control buttons. The gorgeous color LCD screen gives you a clear view of the proceedings, including graphical displays and the operating temperatures of the MOSFETs and power supply. On the back panel, the PLD4.2 boasts four routable female XLR inputs with selectable sensitivity, and six Neutrik Speakon outputs for the speakers (two of which are bridged). Four routable XLR line outputs are also available for daisy-chaining with other amplifiers. Integrated cast aluminum rack handles make moving the amp between shows easier, and it only takes up two spaces on your rack. The locking power inlet socket reduces the chance of an accidental unplugging mid-show. FAST ensures reliable power delivery QSC's Flexible Amplifer Summing Technology (FAST) actively distributes total amp power across one, two, three, or all four outputs, allowing you to get creative with your setup. You can combine full-range speakers, bi-amped speakers, and subwoofers without fear, as PLD amplifiers will get the right juice to them without sacrificing sound quality or impact. Innovation inside QSC's PowerLight power supply with Power Factor Correction (PFC) keeps PLD Series amps humming. PFC aligns the current waveform with the AC main's voltage waveform, for a highly efficient and controlled current draw that'll let you get plenty of juice from a single AC breaker. Multi-stage sleep modes keep power at the ready when you need it while keeping the heat and your energy bills down. Front air inlets and a built-in fan also help to fight against thermal overload. Comes with processing The PLD4.2 gives you plenty of options for tuning your sound from the rack. You can utilize four channels of crossover filters, 5-band parametric EQ, alignment delay, and more. QSC's built-in Intrinsic Correction(tm) filtering system keeps your QSC loudspeaker array tuned to perfection. You have a choice among 50 user presets, and you can save settings for particular rigs and venues for future use. Preset Wizard makes setup easy QSC also includes 20 factory presets for the most common loudspeakers on the market, allowing you to quickly set up your system once you arrive at the club. All you have to do is plug in the speaker model and a few preferences and you'll be ready to rock. You can also hook the amp up to a computer and employ QSC's free Amplifier Navigation software to explore settings on a larger screen or save settings for sharing.
