By PSW Staff • January 23, 2010 QSC K Series compact powered loudspeakers Both accommodate line-level inputs and one may be switched to microphone level sensitivity. Phono (RCA) input jacks are also included for connection of consumer electronics sources (2-way models only). Dual XLR outputs are provided for dual ‘loop-thru’ XLR/M connectors and a single XLR jack is available as a summed output. All three input sources may be utilized at once and mixed via the two gain control knobs (2-way boxes only). Input Panel LED indicators are provided for power, signal present, mic level sensitivity and limit annunciation. A front-mounted power LED may be disabled by means of a rear panel switch when desired, or set so it indicates when the limit circuitry has been engaged. Waveguide Each K model incorporates a conical waveguide that maintains pattern control all the way down to the crossover frequency. The coverage angles of the waveguides are tailored for a smooth transition from woofer to compression driver with far less ‘waist-banding’ or other directivity related anomalies than other products in this class. (click to enlarge) Suspension and Mounting The K Series two-way models may be pole-mounted, suspended or yoke mounted. The K8, K10 and K12 yoke accessory kits allow for either horizontal or vertical yoke mounting, providing a flexible means of attaching K Series loudspeakers to a building structure or truss. When suspended deployment is required, M10 threaded inserts support vertical or horizontal suspension, while the integral pole mount socket accommodates 35mm speaker poles for use on a speaker stand or over a sub. The pole socket is designed so that the speaker may be angled down 7.5° in order to cover the audience while keeping acoustic energy off reflective walls and ceilings.

David Neil Black says I’m in a working rock band and we just used our QSC K-Series System for a 7-week US Tour and are taking it out again for 5 weeks next month. We use K8s for both mains and monitors along with a pair of KSubs. We’ve used them in all kinds of venues, many with poor acoustics, and have enjoyed consistently excellent results.
