Roland KC990 Stereo Mixing Keyboard Amplifier

Roland’s KC-990 stands as the pinnacle of keyboard amplification, combining over two decades of proven KC series heritage with cutting-edge enhancements for today’s professional musicians. This powerhouse delivers 320 watts of stereo sound through dual 12-inch speakers and custom horn tweeters, ensuring accurate reproduction across the full frequency spectrum of 88-note stage pianos, organs, synthesisers, and electronic instruments. The KC-990 functions as a complete stereo sound system, making it perfect for backline amplification, stage monitoring, or even main PA applications.

Connectivity options are comprehensive, featuring four stereo line input channels for keyboards, percussion pads, and drum machines, plus a dedicated auxiliary input supporting smartphones and music players for backing tracks. Channel 1 includes an XLR input for vocal microphones, whilst the Aux In channel accommodates 1/8-inch, RCA, and ¼-inch connections with a monitor function for guide tracks. Built-in effects include Roland’s legendary JC-series chorus, tremolo and rotary effects ideal for organs and electric pianos, plus stereo reverb for vocals and instruments, all controllable via optional footswitches.

Professional integration is seamless thanks to rear-panel stereo line outputs on both XLR and ¼-inch jacks, enabling simultaneous connections to PA systems, monitors, and recording equipment. The XLR outputs feature switchable ground lift to eliminate potential hum issues, whilst a headphones jack provides silent practice and discrete monitoring capabilities. The innovative Stereo Link function allows connection to a second KC-990, doubling available inputs and creating super-wide stereo dispersion by splitting left and right signals across both amplifiers for truly impressive sound coverage.
