    A Closer Look at QSC

    Active Loudspeakers on the Cutting Edge

    Efficient Digital Power, Advanced DSP Circuitry, Innovative Design, and Proven Components Come Together for Excellent Sound. For nearly 50 years, QSC Audio Products have been designing and building some of the most innovative and reliable sound reinforcement equipment available. Based in Costa Mesa, California, QSC manufactures products for professional touring companies, permanent audio installations, the motion picture industry, and for musician and performers just like you.

    KW SeriesIn addition to excellent speaker construction methods and robust cabinet designs, QSC also possesses state-of-the-art electronic circuit technology. Nowhere is this fusion of hardware and intelligent electronics more evident than in the QSC K Series, KW Series, and KLA Series of active, self-powered PA loudspeakers. Each Series is totally unique; yet all share some of the unique innovations that provide foolproof operation, simple system set-ups, plus clean and powerful sound. Meet The Family American Musical Supply is proud to carry the entire K Series, KW Series, and KLA Series from QSC.

    Efficient Class D Power The K Series, KW Series, and KLA Series are driven by an efficient Class D digital amplifier offering 1,000 Watts of continuous power. Every two-way and three-way speaker cabinet features a built-in electronic crossover matched to a pair of 500 Watt modules. This allows each transducer to operate more effectively by playing only the select frequencies that it was designed to reproduce—creating less overall distortion. Subwoofer cabinets feature 1,000 Watts of overall power. Lighter in weight than a traditional amplifier, Class D power also generates less heat. The result is an efficient, lighter weight loudspeaker that runs clean and cool—with less wear and tear on critical components. Intelligent DSP Circuitry Advanced Digital Signal Processing is built into each K Series, KW Series, and KLA Series loudspeaker. From clipping protection to extended bass response, this DSP circuitry goes above and beyond the sonic potential of the transducers and amplifiers to actively enhance and improve the sound for the best possible performance. In the continued absence of an input signal (approx. 5 minutes), active sensing circuitry automatically places the amplifier in the standby mode to conserve power, and to eliminate the need for manually powering down the system. The digital amplification can start up again in a heartbeat as soon as it is needed. Creative Connections K Series and KW Series models are equipped with a two-channel mixer with independent level controls. In addition to XLR and 1/4" connectors with Mic and Line level switching, stereo RCA jacks are also provided. KLA Series loudspeakers feature active controls that re-tune the cabinet response—based on the number of cabinets being used—for optimal sound. In addition, all models in all series feature a convenient pass-thru line output for daisy-chaining multiple cabinets together for a custom setup. K SeriesVersatile Cabinet Design All of the K Series, KW Series, and KLA Series loudspeakers feature comfortable handles for easy transport and positioning. In addition, each provides both pole-mount fixtures and M-10 rigging points for flying the cabinets. The SOLO™ Rigging System—exclusive to QSC—allows multiple KLA Series cabinets to be locked together for advanced Line Array applications. In addition, optional mounting frames allow KLA Series cabinets to be shaped into a fly-able array. Steel grilles deliver an extra level of speaker protection. Remote Control Using a compatible remote control unit allows the output level to be adjusted without having to get in behind the cabinet. In addition, a single remote can control any and all QSC K Series, KW Series, and KLA Series loudspeakers used in a single system. For system monitoring, all models offer a three-way switch for the front-facing LED, so it can serve as a power light, a peak/clip indicator, or it can be set to remain dark for more discreet applications. Superior Sound Exceptional Low and Mid frequency drivers, powerful amplifiers, and an efficient cabinet design combine to deliver satisfying sound in any venue. Regardless of model, each two-way and three-way loudspeaker features a robust high-frequency compression driver with a generous 1.75" diaphragm. The result is tight, rich bass and clean, crisp highs.

    QSC K SERIES ACTIVE LOUDSPEAKERS

    The New Standard for Portable Sound

    Equipped with extensive input mixing and effective sound-shaping controls, the QSC K Series adds real-world versatility and enhanced performance to the traditional active loudspeaker. Efficient digital amplification and impact-resistant ABS enclosures endow the QSC K Series with a compact size and a lighter weight that allows simple set-up and easy transport. The KSub subwoofer is constructed of select birch plywood. The K Series provides four distinct models:

The Tilt-Direct™ pole-mount fitting—a QSC exclusive—allows a downward tilt of the cabinet by 7.5° to minimize reflections and increase coverage. In addition, built-in M10 rigging points allow the K Series loudspeakers to be flown in an overhead array. Unlike traditional pole-mount bases, the KSub offers a threaded base and matching pole that eliminate wobble and increase system efficiency—another QSC innovation.

    QSC KW SERIES ACTIVE LOUDSPEAKERS

    The Wooden-Cabinet Workhorse

    Unlike the K Series loudspeakers, the entire QSC KW Series is constructed with precision-milled birch plywood cabinets. These rugged road-ready cabinets offer the same extensive input mixing and effective sound-shaping controls shared by the K Series and KLA Series. Despite all of the exclusive QSC innovations, the KW Series remain lighter than traditional wooden loudspeakers—allowing simple set-up and easy transport. In addition, the KW153 introduces a unique three-way loudspeaker. The KW Series provides four distinct models:

    QSC KLA SERIES ACTIVE LOUDSPEAKERS

    Proven K Series Performance in a True Line Array Package

    Are you ready for the next step in sound system evolution? The KLA Series from QSC retains the highly acclaimed Class D amplifier, exceptional 1.75" high-frequency compression driver, and robust low-range speakers that have defined the successful sound of the K Series and KW Series. What makes the innovative and easy-to-use KLA Series different is their unique ability to self-assemble into a true Line Array system. Best of all, the KLA Series delivers all of the advantages of a line array system—modular design; space-specific installation and coverage; patch-thru power and audio connections; multiple rigging options—with none of the disadvantages.

    With the KLA Series, there is no need for difficult calculations, racks of amplifiers, or elaborate signal processing. The totally revolutionary SOLO™ (Single Operator LOgistics) system allows multiple units to latch together in seconds to form the basis of a Line Array system—no tools required! Add to that the exclusive Ar-Q™ Arcuate Equalization control system. Simply rotate the dial to select the number of KLA Series modules in use, and the EQ and sound are automatically optimized to match your array. The days of manually setting the gain and EQ for each module are over.


    The KLA Series provides two distinct models:

    KLA Series:

The SOLO mounting hardware is completely self-contained in each loudspeaker; simply extended the latch to connect an additional cabinet, and pull the handle down to lock it in place. It’s that simple. Up to five units can be locked together; thanks to the energy efficient design, all five modules can be run from a single 15 amp 120 Volt outlet. In addition to the XLR audio input—featuring a dedicated Gain knob—there is an XLR output to pass the input signal along to the next module. Locking PowerCon™ AC cables and XLR Audio jumpers are included to build your system. An additional connection point allows remote volume control using a compatible controller.
