KC-990 Keyboard Amplifier
Worth It Every Time
For over two decades, keyboard players everywhere have relied on Roland’s KC amps for their powerful high-fidelity sound, onboard mixing features, versatile connectivity, and lasting durability. The latest generation carries on the time-honored KC benchmark of quality while offering new enhancements tuned for the needs of today’s working musicians. With a KC amp by your side, you’re in complete control of your stage rig, so you’ll always sound great and play your best. And that’s worth it every time.
The flagship KC-990 is a performance powerhouse filled with high-end features. Offering four onboard DSP effects, four stereo input channels, a stereo aux input, and support for an XLR vocal mic, it’s a great all-in-one solution for players with large keyboard setups and small groups performing with electronic instruments and backing tracks. The KC-990 delivers big, full sound for both stage monitoring and PA use, thanks to its stereo speaker configuration and 320 watts of total power. And with Stereo Link capability, you can seamlessly add a second KC-990 when you need more inputs and broader sound coverage.
- Flagship stereo keyboard amplifier with 320 watts of power

- Built-in effects: reverb, chorus, tremolo, and rotary
- Control rotary speed and effects on/off with optional external footswitches
- Flexible I/O with XLR mic input, stereo XLR and ¼-inch line outputs, headphones output, and more

Full-Range Stereo Sound for High-Impact Performances
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.
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-inch, RCA, and ¼-inch connections, and features a handy monitor function for working with guide tracks on stage.
Built-In Stereo Effects
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.
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 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.
Expand Your Setup with Stereo Link
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.

Keysound reviews
Yamaha Pre-Owned PSRSX900 Piano
The sales team are always helpful and give good advice. Their products are always tested before delivery. Keyboard delivery is always on time and at a date to suit my situation. The keyboard I received was preloved but in mint condition and is a joy to play. I look forward to dealing with keysound for future purposes.
Yamaha PSRE473 Keyboard
We had a long trip to Hinkley to See Steve and his wife at Keysound due to Lincoln having no keyboard shops. We were so pleased we did. They were both brilliant hosts for the time we was in the shop. There range of keyboards is excellent and they were demonstrated brilliantly by Steve who was inspirational and gave my son a real appreciation for what can be done. Many thanks
Yamaha Pre-Owned Tyros 5 XL Keyboard

Yamaha Genos 2XXL Keyboard
Excellent....above and beyond.
Yamaha Genos 2 Keyboard
From start to finish, my experience with Keysound was nothing short of exceptional. Delivery was easy, with my keyboard arriving as promised on time and in perfect condition. A good explanation of the Genos 2 was given to me on delivery and everything was setup ready to go. The USB they provided was helpful in exploring the capabilities of my new keyboard.
Any enquiries I had were met with prompt and friendly responses, and they went above and beyond to ensure that I had all the information I needed.
Overall, based on my experience, I would recommend Keysound for their combination of knowledge, reliability, and excellent customer service.

Cannot find fault on service and prices. Will never use any other dealer.
Yamaha CSP295-PE Piano
Keysound are the most knowledgeable And helpful people ever I cannot rate them high enough. Our Piano was delivered on time and the guys told me at the time that the packaging was damaged when they unpacked the piano they found it to be damaged and told me before I even seen it. I had the choice to send it back then or keep it until the replacement was found. I kept it within two weeks. I’ve got a Piano. First rate service all around. I would highly recommend them
Yamaha PSRSX600 Keyboard

Roland Fantom 06 Keyboard
I have purchased several keyboards from Keysound , and you always get a good service. You get a more personal experience, and they are always willing to take time to find you the best keyboard which suits your needs. After sales is also good, as they will help you with your new keyboard should you get stuck on anything.
Yamaha Pre-Owned Genos XL Keyboard
Nothing too much trouble and great after sales support and assistance.
Korg PA5X61 Keyboard
Great personalised friendly service, extremely knowledgeable of the products. I would recommend Keysound, especially to those who require additional support or aftercare with the products they purchase.
Casio CTX5000 Keyboard
Keysound were excellent. Other music shops take a generic approach about what people want and they have limited experience across multiple types of instruments. Keysound were interested in me and exacty what I wanted. They interpreted that and gave me invaluable advice. It was friendly, focused and specific. I would definitely recommend them and buy from then again. I also really like their view that buying a keyboard from them is just the start of the journey. They are there for in-person and online/on phone advice and help. I am extremely pleased with my purchase - which is not what I thought I'd be buying when I entered their shop.
Kawai CN301-B Piano
Very knowledgeable and helpful to make sure we got the correct piano for us
Yamaha Genos 2XL Keyboard
Steve and his staff were excellent. They spent a lot of time explaining and demonstrating various digital pianos and keyboards. After a few days deliberating I chose a different option to what I had set out to buy. The knowledge and service was second to none and inspired me to become a better player. I am very pleased with my purchase and looking forward to many hours of keyboard playing. Thank you
Roland HP702-CH Piano
I am so pleased I chose to visit Keysound Hinckley and purchase my new piano from them!!
I went in store to browse as I haven't bought a new piano in about 15 years, and the person who helped me (Sorry, I didn't get his name!) was so so helpful and knowledgable. I purchased my piano and within a week got the call to arrange delivery the following weekend!
The piano is amazing, but unfortunately has an issue with one of the keys. And rather than sending someone over to fix it, the manager called me yesterday to say they'll arrange for the piano to be replaced with a new one!! He said he would be happy if a brand new piano already had an issue, so he'd rather I have a brand new one. Honestly, couldn't ask for better service and nicer people :) Thank you so so much.
