Multi Channel Keyboard Combo. Packed with many new design features, the KC-400 updates the previous-generation KC-350, a longtime players’ favorite. The power has been increased to 150 watts, and the two-way speaker system features a newly designed 12-inch custom woofer for improved sound quality. In addition, the power section has been completely redesigned for better stability, enhanced bass reproduction, and reduced weight. With the KC-400’s built-in mixer, you’re able to connect a variety of stereo keyboards and instruments, plus an XLR vocal mic. And via the Stereo Link function, you can easily chain a second KC-400 for more inputs and true stereo amplification on stage. Very Good Condition. w/manual
