QSC KC12 is a 3-way powered column PA system with 3000 watts of Class D power, a 12-inch subwoofer, two 4-inch midrange drivers and a 1-inch compression driver. It covers 145° horizontal by 35° vertical, reaches 132 dB peak, and adds Bluetooth with True Wireless Stereo, a 3-channel mixer and app control. It comes in black or white.
A column system with a real compression driver and a 12-inch sub, not a stack of small full-range drivers.
The KC12, which QSC calls the K Column, takes the sound of a traditional box speaker and puts it in a column format. The KC12S subwoofer carries a 2000 watt amplifier and the KC12T column a 1000 watt amplifier. The column uses dual 4-inch midrange drivers and a compression driver on the QSC LEAF (Length-Equalized Acoustic Flare) waveguide for wide, even coverage.
A built-in 3-channel mixer takes two mic/line combo inputs, a 3.5 mm stereo input and Bluetooth. The onboard display gives access to global parametric EQ, delay up to 200 ms, reverb, factory presets for DJ, live music and speech, and saved Scenes. Two XLR outputs provide a loop-thru and an assignable post-DSP mix output, and a USB-C port charges a phone or tablet and handles firmware updates.
It sets up tall, with the 32-inch pole between sub and column, or short, with the column sitting directly on the sub for stages and risers. The whole system weighs 60.3 lb, and a tote for the column and pole is included.
