Ultimate Real-World Headroom

more than doubles the output power and thermal capacity of our previous 2RU designs, but it looks and sounds “linear,” whether on the bench or driving speakers. Rigorous testing and precise alignment of feedback networks produce stable closed- loop response.

The modulator converts analog input sig- nals into varying on-off ratios – the PL380 amplifi er’s responds in under 5 nanosec- onds. A crystal controlled, synchronized power supply and Class D clocks prevent interference between power stages.

Our new Class D switching section uses a single pair of industrial strength devices that easily handle kilowatts of energy without extra complexity. Our painstakingly refi ned PCB design controls high frequency cur- rents to prevent internal interference. A proprietary dynamic current limiter monitors power stress in the output devices, deliver- ing the maximum power possible within safe operating limits.

Output ﬁ ltering is another key to ultimate audio performance. Proprietary winding techniques pack more copper on a smaller coil, for better effi ciency and lower distortion.

If you’ve been up on the riser ringing out drum monitors, or out at FOH aligning the subs with the mains, you know that head- room is not measured by instantaneous peak power ratings. It’s the ability of the entire amplifi er, from power supply to output devices, to produce high voltages and cur- rents for extended periods of time. Power- Light 3 Series amplifi ers go head-to-head with products claiming much higher output.

Ultimate System Compatibility

Zero Signal Latency

Of course the PowerLight 3 Series has DSP options. But none of them impose a latency penalty inside the amplifi er. There’s no other way to ensure compatibility with other amplifi ers; no other way to avoid

compromising signal alignment in multi-way sound systems.

Flexible System Architecture Choices: they’re what the PowerLight 3 Series is all about. Upgrade analog racks and monitor them on stage. Go all the way to fully networked digital signal distribution and processing with remote system manage- ment. Combine elements of both approach- es. It’s your decision, as it should be.

Ultimate Ruggedness

The real art of amplifi er design is deliver- ing ultimate power output while protecting the entire system. Like all QSC designs, PowerLight 3 Series amplifi ers had to pass every one of our electrical and mechanical stress tests – so tough, we’ve never found another amplifi er brand that has survived the full test cycle.

3 Series specifications

The QSC Audio 3 Series is a remarkable lineup of professional audio products designed to deliver exceptional sound quality and reliability. Tailored for various applications including touring, rental, and installation, this series exemplifies QSC's commitment to innovation and performance.

One of the standout features of the 3 Series is its advanced Class-D amplification, which not only provides high efficiency but also produces remarkable power density. This means that users can achieve greater output with less energy consumption, making it an environmentally friendly choice without sacrificing performance. The amplifiers in this series are designed to provide high headroom, ensuring dynamic musical peaks are handled effortlessly.

In addition, the 3 Series incorporates QSC’s unique Directivity Matched Transition (DMT) technology. 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.
