QSC Highlights K Series Compact Powered Loudspeakers At 2010 Winter NAMM

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.

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.
