QSC has launched two new power amplifier families at InfoComm 2013 – PLD and CXD. The PLD family is for portable live sound reinforcement, while CXD amplifiers are designed to meet the needs of integrators, The two ranges share a common four-channel Class-D platform.
Key to the new models is QSC’s Flexible Amplifier Summing Technology (FAST) and a new design of MOSFET power drive which enables power to be deployed across one, two, three, or four channels. “Our new CXD and PLD amps represent a major advancement in amplifier technology and innovation,” says Dale Sandberg, QSC senior product manager, Amplifiers. “Not only are they amazing Class-D amplifiers with on-board processing, but they change the fundamental amp paradigm with a unique channel combining methodology for much greater flexibility.” The FAST design “meets the needs of our customers in a whole new way", he adds. “There’s been a misconception that QSC was moving away from power amplifier products and instead focusing our attention on loudspeakers and DSP,” states Gerry Tschetter, VP marketing. “While we’ve seen tremendous success in those product categories in recent years, the fact remains that QSC still builds the best power amplifiers in the market. Our new CXD and PLD amplifiers are a reflection of our use of cutting edge technologies, our deep understanding of DSP and loudspeaker engineering and our legacy of over 40 years of rock solid amplifier design.”
The PLD line runs from the PLD4.2 (400W @ 8 ohms, continuous) to the PLD4.5 (1,150W @ 8 ohms, continuous). The rear panel features four balanced XLR input connectors with loop-thru and six (Speakon NL4 loudspeaker connectors for easy setup. The on-board DSP processing is managed via front panel controls with 20 factory settings included for the most common applications. The CXD series has been designed to address a number of demands from the installation market: multichannel amplifiers, with high power density (to minimise space usage in racks), on-board DSP, high efficiency, and the ability to drive low-impedance as well as 70/100V high-impedance loads. Accessible via the front panel, the Preset Wizard also enables presets to be created, stored, recalled and edited. It assigns loudspeakers to outputs and loads the speaker tuning into the DSP. Tunings for approximately 70 models of speaker from around a dozen manufacturers are available, according to Sandberg. Pictured with models from the two ranges at a launch event on Tuesday are (L-R) Matt Skogmo (digital systems hardware architect), Jerry Tschetter (vice president, marketing) and Dale Sandberg (senior product manager).
