Full-Range Stereo Sound for High-Impact Performances

The KC-990 offers full-range stereo sound reproduction with 320 watts of power (180 watts x 2), two newly designed 12" speakers, and two custom horn tweeters. The cabinet features Roland’s patented twin bass-reflex design, which delivers extended low-frequency response without distortion. 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.

Onboard Mixing for Big Rigs and Full Groups

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", RCA, and 1/4" connections, and features a handy monitor function for working with guide tracks on stage.

Built-In Stereo Effects

The KC-900 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.

Versatile Connectivity for Performing, Recording, and Practice

With its rear-panel connectivity, the KC-990 integrates easily into any playing environment. Stereo line outputs are provided on both XLR and 1/4" inch jacks, offering simultaneous connections for interfacing with PA systems, stage monitors, and recording devices.

"This amp rules over all other keyboard amps"
Overall: 5 out of 5 stars
Verified Customer zZounds has verified that this reviewer made a purchase from us.
After doing an extended amount of research and testing amps at my local music stores. I came across this one and it’s the flagship of all flagships. The effects are clear and very functional. The tweeters deliver ear piercing highs and the subs deliver beautiful mids and house rattling Lows. No loud overtones and at very high volumes no distortion whatsoever. I’ve only had mine turned up to 80% so don’t know exactly where the cut off is it as far as no distortion but that was way too loud for me. I played through it at our church running my keyboard through it and I’ve only played it at the church at 35% and it’s more than enough and our church is quite large can seat 100 plus. Also with the band I’m in every time I put low in frequencies through it the bass player gives me this look of yeah that amp rocks dude. You will not be disappointed so if you’ve been thinking about it do it.
