Independent shopping perspective
The Korena take
At 150 watts, the KC-400 is a four-channel keyboard amplifier with onboard mixing, a 12-inch woofer, and a separate tweeter. It accepts stereo keyboards and instruments, an XLR vocal mic, and auxiliary audio, then offers stereo line outputs for PA systems, stage monitors, or recording devices. Stereo Link lets two KC-400 units work together for stereo operation or added channels. A Sub Out supports a powered subwoofer, while the headphone jack covers silent practice and discreet monitoring.
