By combining the KX12 with active K-array subwoofers, three portable systems are created, which differ in size of the subwoofers and number of KX12 units used. With powered subwoofers that maintain the same digital editing features of all K-array active subwoofers, the KRX systems feature an integrated touch screen, providing intuitive control over the main DSP functions, such as input/output levels, signal routing, offset delays for subwoofer and mid-high speaker output (up to 12 ms each) and overall system delays (up to 330 ms). All DSP functions, including EQ, can also be controlled remotely via software through USB or RS485 (3 pin XLR). With the K-dante accessory, the systems can be used in a Dante network. The KRX402 is the middle range system that delivers more pressure and a more extended bass response than the smaller KRX202. The stereo system is comprised of two KX12 speakers paired with one 21” KMT21 subwoofer by means of an extendable pole and proper joining and stacking hardware per side. Possible applications are DJ use, clubs and anywhere a lot of pressure is needed close to the speakers.
