Overview:
Providing remarkable low-end for the KC12 active 3-way column loudspeaker system, the QSC KSC12S is a 12" subwoofer module with a 3000W amplifier and a full complement of digital signal processing. The rear panel offers two combo XLR-1/4" inputs and a stereo 3.5mm TRS aux input.
There are three physical gain knobs and a multifunction digital display for controlling loudspeaker functions. Integrated Bluetooth allows for True Wireless Stereo (TWS) for easily pairing music sources for both left and right speakers wirelessly.
