The KC-990 offers full-range stereo sound reproduction with 320 watts of power (160 watts x 2), two newly designed 12-inch speakers, and two custom horn tweeters. This allows the KC-990 to accurately reproduce the wide frequency range of 88-note stage pianos, organs, and synthesizers, as well as rhythm machines and other electronic instruments.
Roland’s most powerful KC amp is a complete stereo sound system in a single package, making it ideal for backline amplification, stage monitoring, and even main PA use. With four stereo line input channels available, you can connect keyboards, percussion pads, drum machines, and more. There’s also a dedicated auxiliary input to plug in a smartphone or music player for backing tracks. Channel 1 includes an XLR input too, allowing you to connect a vocal mic for even more versatility. The Aux In channel supports 1/8-inch, RCA, and ¼-inch connections, and features a handy monitor function for working with guide tracks on stage.
The KC-990 comes equipped with four different effects for sweetening your live sound. The chorus effect is derived from Roland’s world-famous JC-series amps, providing unmatched depth and dimension through the KC-990’s stereo speakers. The amp also includes tremolo and rotary effects that work great with organs and electric pianos, plus a lush stereo reverb for vocals and instruments. By connecting optional footswitches, you can turn the effects on/off and control rotary speed hands-free while performing.
With its rear-panel connectivity, the KC-990 integrates easily into any playing environment. Stereo line outputs are provided on both XLR and ¼-inch jacks, offering simultaneous connections for interfacing with PA systems, stage monitors, and recording devices. The XLR outputs also have a switchable ground lift, which eliminates hum that can sometimes occur when connecting to a main PA. There’s a headphones jack too, perfect for silent practice sessions and discrete monitoring of guide tracks and instruments on stage.
If you ever need to expand your inputs or sound coverage, the KC-990’s Stereo Link function makes it simple. First off, the number of available inputs doubles when you connect to the two stereo link jacks on a second KC-990. In addition, the left and right signals of connected instruments are split across the two amps, providing super-wide stereo dispersion for even more impressive sound.
