K Series Features Tour

1000 Watts

Loudspeaker manufacturers typically have two separate amplifiers in their powered speakers. Although they share a common power supply, the amplifiers operate very differently and output different power levels. While this approach can make for a streamlined, efficient design, it usually results in a less capable high frequency amp. As a result, the amplifier is easily over-driven if the operator pushes the system hard. The resulting high-frequency distortion is audible and may destroy the compression driver.

K Series is different. First, K Series gets its name from the industry-best kilowatt amplifier module that drives its performance. Rated for 1,000 watts of continuous available power, this state of the art, light-weight Class-D module is comprised of both a 500 watt low-frequency (LF) amplifier and a 500 watt high-frequency (HF) amplifier (two 500 watt LF amplifiers in the K Sub). The 500 watts of HF amplification makes it nearly impossible to drive the system into distortion by pushing the amp beyond its design limits. The result is a cleaner sound and a far more robust design.

The QSC kilowatt amplifier defines another key difference between K Series and traditional powered speaker systems. All K Series models, regardless of woofer diameter use the same kilowatt power module. Only the input circuitry and DSP programming differ from model to model. No longer does a smaller-format powered loudspeaker have to be equated with lower power and less total performance.
