To prevent unauthorized adjustment of input attenuation settings, a security lockout plate is included with every PowerLight 3 amplifier.

PL340 & PL325: World-Proven

PowerLight Technology and

Ultimate Class H Performance

Choose Your Technology

Maybe you don’t need the PL380 amplifier’s 8 kW output. Perhaps you prefer the sound of linear output amplifiers for your high- frequency drivers. The PowerLight 3 Power Amplification System offers you two excep- tional choices — the PL325 and PL340. Both amplifiers update QSC’s well-tested Powerlight 2 platform, a unique Class H technology that eliminates audible artifacts caused by switching between tiers. Their highly refined linear circuitry delivers the cleanest output signal available in a profes- sional power amplifier.

Our latest PowerLight supply has larger capacitors and more robust semiconduc- tors for even higher peak power and energy storage. As always, PowerLight is designed for the places you work, tolerating surges and dips gracefully.

Smooth System Integration

The PowerLight 3 Series is designed as a complete system for high-power concert amplification, not just a group of products. That’s why all PowerLight 3 amplifiers share a common control, connector and indicator layout: it simplifies building and/or reconfig- uring your racks, and keeps your wiring neat and clean.

You may want to use other amplifiers alongside the PowerLight 3 Series. That’s why all three of these amplifiers have both switchable input sensitivity and zero latency.

Reliable Protection

We take thermal overload as seriously as you do. PowerLight 3 Series fans speed up if heat sinks rise above 55° C. Increased air flow is usually enough even during high level operation. Limiting begins above 80° C. Temperatures above 85° C only occur with fan or vent blockage: the amplifier will mute to prevent significant internal damage.

Global Regulatory Compliance

If your business is concert sound, you never know how far the next gig will take you — or what kind of regulations you’ll find when you get there. PowerLight 3 Series amplifiers carry both UL and CE approvals, and meet world recognized FCC Class A EMI limits for the PL380 and Class B for the PL325 and PL340.

This innovation ensures that the sound remains consistent across the listening area, providing a more uniform response. By carefully controlling the dispersion of sound, DMT works to minimize dead spots, allowing audiences to enjoy a balanced mix regardless of their location within the venue.

Another significant characteristic of the QSC 3 Series is its robust construction. Built to withstand the rigors of professional use, the speakers are housed in durable enclosures designed to handle the demands of both indoor and outdoor environments. The components are engineered for longevity, ensuring that users can rely on these systems for years of exceptional performance.

Moreover, the 3 Series integrates seamlessly with QSC's Q-SYS Ecosystem, allowing for digital signal processing (DSP) and network control. This connectivity feature enhances flexibility, enabling easy integration into existing systems and improving overall workflow. With customizable presets and intuitive software, sound engineers can fine-tune every aspect of audio delivery to match the specific needs of any event.

The QSC Audio 3 Series also emphasizes versatility, offering a range of models that cater to different sound reinforcement needs. From small portable units suitable for intimate venues to larger systems capable of filling concert halls, this series has something for everyone.

In conclusion, the QSC Audio 3 Series combines cutting-edge technology, efficient design, and superior sound quality, making it a preferred choice among audio professionals. Whether for live performances, corporate events, or installations, the 3 Series stands out as a reliable and high-performing audio solution.
