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.
In 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.2 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.2 Series, KW Series, and KLA Series from QSC.
Efficient Class D Power
The K.2 Series, KW Series, and KLA Series are all driven by an efficient Class D digital amplifier. The KW Series and KLA Series all offer 1,000 Watts of continuous power and 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. The latest K.2 Series models deliver a staggering 2,000 Watts of clean, continuous Class D power. Subwoofer cabinets feature 1,000 Watts of overall power. Lighter in weight than a traditional amplifier, Class D amplification 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.2 Series, KW Series, and KLA Series loudspeaker. From clipping protection to custom-configured bass response, this DSP circuitry works to improve the sound for the best possible performance. The K.2 models provide a programmable 4-Band Parametric EQ, delay/time alignment options, and nearly a dozen preset EQ/DSP settings that can be selected based on application – plus five user preset scenes for saving custom configurations. In the continued absence of an input signal (approx. 5 minutes), KW Series and KLA Series loudspeakers offer active sensing circuitry that 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.
K.2 Series loudspeakers provide three sets of inputs, each with an independent volume knob. Balanced XLR and 1/4" inputs (with a Hi-Z level switch) and a 1/8" TRS summed mini jack are provided. 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.
Versatile Cabinet Design
All of the K.2 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. Optional yoke brackets are also available for the K.2 Series models when used in permanent installations. 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.
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 KW Series and KLA Series loudspeakers used in a single system. For system monitoring, all models allow the front-facing LED to serve as a power indicator, or it can be set to remain dark for more discreet applications.
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 1.4" to 1.75" diaphragm. The result is tight, rich bass and clean, crisp highs. Explore each of the QSC loudspeakers available at American Musical Supply and discover your next loudspeaker system.
