Active PA Speaker QSC KC12 (Black)

The QSC KC12 is a powerful three-way active column array system designed for mobile performers, DJs, musicians, and installations where high sound quality, ease of setup, and acoustic power are important. It combines modern design, 3000 watts of peak power, and unique QSC technologies in an extremely portable format.

The system consists of a 12-inch phase-inverted subwoofer, two 4-inch midrange drivers, and a 1-inch compression driver accompanied by QSC's patented LEAF™ waveguide, providing wide horizontal coverage (145°) and directional vertical dispersion (35°). As a result, the KC12 delivers clear, natural sound at any volume level with a maximum SPL of 132 dB.

The KC12 has two combo Jack/XLR inputs with Hi-Z and +48 V phantom power switches, a 3.5 mm stereo input, USB-C (5 V / 3 A), Bluetooth with True Wireless Stereo support for wireless connection of two systems, and a built-in DSP with a digital display for EQ settings, presets, delay, and reverb. The column section (KC12T) weighs only 4 kg and is transported in a complete case together with an adapter stand (KC-SP32). An optional subwoofer case (KC12S-CVR) is available.
