INFOCOMM 2013: QSC unveils two new power amp lines

QSC has launched a pair of new amplifier ranges – the CXD Series for installed sound and the PLD Series for live sound reinforcement.

Housed in a 2U rack-mount configuration, the CXD and PLD Series amplifiers feature QSC’s new proprietary class-D power devices. Flexible Amplifier Summing Technology (FAST) offers improved power allocation by actively distributing the total amplifier power across one, two, three or all four outputs, enabling amp channels to be combined for maximum current or voltage output, with the largest models capable of up to 5,000 Watts.

With independent DSP processing available for every channel, a preset wizard streamlines the setup process, simplifying amplifier configuration and deployment. Advanced DSP includes cross-over filters, parametric EQ and alignment delay, and when paired with QSC loudspeakers, Intrinsic Correction processing techniques can be employed to ensure "optimum sonic performance." The integration of DSP with amplification means that the onboard processor is aware of what the amplifier is doing. This enables the dynamics processing and protection circuitry to be far more accurate and effective. USB interfaces allow for firmware updates, along with the ability to upload loudspeaker tunings and configurations, as well as transfer data between amplifiers.

Designed specifically for integrators, CXD Series amplifiers (pictured) provide efficient, robust and high fidelity power capable of driving multiple amplifier channels and loudspeaker configurations while simultaneously deploying digital processing – all with optimal energy and efficiency. The CXD lineup includes the CXD4.2 (400W @ 8 ohms, continuous), the CXD4.3 (625W @ 8 ohms, continuous) and the CXD4.5 (1150W @ 8 ohms, continuous) with the CXD 4.3 and CXD4.5 able to direct-drive 70V and 100V systems. The rear panel features four balanced Euroblock input connectors and four Euroblock touch-proof loudspeaker connectors, enabling integrators to terminate wiring before connecting to the amplifier. GPIO located on the rear panel offers additional functionality, including a heartbeat output for Life-Safety supervision.

PLD Series Amplifiers, designed specifically for portable sound applications, are designed to drive multiple channels of loudspeakers while simultaneously deploying digital processing, all with minimal operational complexity. The PLD line consists of the PLD4.2 (400W @ 8 ohms, continuous), the PLD4.3 (625W @ 8 ohms, continuous) and the PLD4.5 (1150W @ 8 ohms, continuous). The rear panel features four balanced XLR input connectors with loop-thru and six Speakon NL4 loudspeaker connectors for easy setup. On-board processing is managed via front panel controls with 20 factory settings included for the most common applications. For more customised settings, the Configuration Wizard helps streamline system setup and configuration.

CXD and PLD Series Amplifiers will be available in July 2013.
