Cooling

Air flows from the rack, into the back of the amplifier, and out the front. This keeps the rack cool. The fan automatically runs faster when the amp is working hard.

Do not block the front or rear air vents!

Air flow in QSC amplifiers: Cool air is drawn into the rear of the amplifier by the cooling fan. Warm air exits the front of the amplifier.

AC Mains Connection

Connect AC power to the IEC socket on the back of the amplifier. NOTE: Turn off the AC power switch before connecting AC power. Connect the AC mains plug to a suitable AC mains outlet.

The correct AC line voltage is shown on the serial number label, on the rear panel. Connecting to the wrong line voltage may damage the amplifier or increase the risk of electric shock.

The rear chassis ear can be used to retain the IEC power connector. After inserting the IEC block into the recepta- cle, use a wire-tie or similar device to secure the cord to the chassis ear.

Orient the IEC connector with the connector prongs in the socket, then push the connector firmly into the IEC socket until fully seated.

AC Mains Current Draw

The table at the right provides typical current draw for each model as a function of load and output power level. Units of measurement are amperes rms.

NOTE! Current draw shown is for 120 VAC line. For 230 VAC models, multiply values shown by 0.5.

•1/8 power (pink noise) represents typical program with occa- sional clipping. Use this rating for most applications.

•1/3 power (pink noise) represents severe program with heavy clipping.

•Full power (sine) is continuous sine wave driven at 1% clipping. •PLX 1802, PLX 2502, PLX 3102, and PLX 3602 models: Thermal

or overcurrent cutback limits duration of full power 2 ohm operation. Long term, active limiting to 30A at 120V.

•PLX 1104 and PLX 1804 models: Long-term, circuit breaker lim- ited to 15A at 120V.

The PLX2502 serves as a powerful amplifier capable of delivering 2,500 watts at 4 ohms. Its lightweight construction makes it easy to transport, while the efficient PowerLight™ technology helps reduce energy consumption without compromising performance. This model features dual independent channels, allowing for versatile operation and flexibility in wiring configurations.

The PLX1804, on the other hand, offers slightly lower output while still delivering a solid 1,800 watts at 4 ohms. This model combines superior sound quality with a user-friendly interface. The specially designed fan cooling system ensures that the amplifier remains efficient even during demanding performance conditions. It also comes equipped with XLR and TRS inputs, providing compatibility with a wide range of audio sources.

For those requiring even more power, the PLX3602 stands out with a massive 3,600 watts at 4 ohms. Its all-steel chassis enhances durability, making it suitable for rigorous touring environments. Additionally, the integrated DSP offers protection against overheating, short-circuits, and overloads. With its extensive range of outputs, the PLX3602 supports complex setups involving multiple speakers and driving high-demand audio systems.

The PLX3102 is another noteworthy model in the series, providing an output of 3,100 watts. This amplifier emphasizes versatility and can drive various speaker configurations efficiently. It features both binding post and Speakon outputs, ensuring secure and reliable connections, even in high-stress scenarios.

Lastly, the PLX1802 rounds out the series with 1,800 watts of power. Known for its compact size, it is particularly suited for smaller venues or as a monitor amplifier. Despite its smaller footprint, the PLX1802 retains the robust performance characteristics that QSC is known for.

Overall, the PLX series epitomizes QSC’s dedication to quality audio amplification, combining power, portability, and advanced features across an impressive range of models. With their advanced technologies, including PowerLight™ and integrated DSP, these amplifiers are designed to meet the rigorous demands of both live and installed sound applications while delivering exceptional sound quality.
