KC-400 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.
Packed with many new design features, the KC-400 updates the previous-generation KC-350, a longtime players’ favorite. The power has been increased to 150 watts, and the two-way speaker system features a newly designed 12-inch custom woofer for improved sound quality. In addition, the power section has been completely redesigned for better stability, enhanced bass reproduction, and reduced weight. With the KC-400’s built-in mixer, you’re able to connect a variety of stereo keyboards and instruments, plus an XLR vocal mic. And via the Stereo Link function, you can easily chain a second KC-400 for more inputs and true stereo amplification on stage.

Full-Range Sound for Keyboards and Electronic Musical Instruments
The KC-400 offers powerful, punchy sound and full-range audio reproduction in a compact amp with 150 watts of power. The cabinet features Roland’s patented twin bass-reflex design, providing extended low-frequency response without distortion. Paired with the newly redesigned power section, the KC-400 delivers even better bass performance for amplifying 88-note stage pianos, organs, and synthesizers, plus rhythm machines and other electronic instruments. An added benefit of the efficient new power section is reduced weight, making the KC-400 easier to carry from gig to gig.
Onboard Stereo Mixing
Via the KC-400’s four line input channels, 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. The line and aux inputs support stereo connections, allowing you to send stereo sound to a PA or recording device, and also amplify in stereo when connecting a second KC-400 through Stereo Link. Channel 1 includes an XLR input too, letting you plug in a vocal mic for even more versatility. And with the convenient Output Select function on Channel 4, there’s lots of flexibility for monitoring click and guide tracks while performing.
Versatile Connectivity for Performing, Recording, and Practice
With its easy-access connectivity, the KC-400 integrates into any playing environment. Stereo line outputs are provided on 1/4-inch jacks for interfacing with PA systems, stage monitors, and recording devices. There’s also a Sub Out jack for connecting to a powered subwoofer, with level conveniently tied to the amp’s master volume for one-touch control. The KC-400 has a headphones jack as well, perfect for silent practice sessions and discrete stage monitoring.
Expand Your Setup with Stereo Link
If you ever want to expand your inputs or monitor in stereo, the KC-400’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-400. In addition, the left and right signals of connected stereo instruments are split across the two amps, allowing you to bring a studio-like monitoring experience to your stage performance setup.

Keysound reviews
Roland FP30XP-B Piano
The service couldn’t have been better. I told Steve my budget, he gave me his opinion, I tried several pianos within my budget and way above it and was able to make my decision easily. There was only useful help and advice at hand - no pushiness! Thank you.
Korg PA5X61 Keyboard
Excellent service from Steve who showed me what the keyboard would do. The shop is much easier to get to and has a large carpark.
Yamaha Refurbished P525B Piano
Couldn't have been more helpful particularly as I was buying this piano without trying it or seeing it. I was able to part exchange my old keyboard and this too was hassle free - it was collected at the same time as the new piano was delivered. Great service from a great company with very helpful staff.
Yamaha Pre-Owned DGX670-B Piano
The guys at Keysound really have great knowledge. It's obvious they enjoy their work which means I enjoyed being in the store.
Enthusiastic people really do up the level of service.
Roland HP704-DR Piano
The service at Keysound is second to none, and the expertise of Steve, the manager, is outstanding! Although I am a retired piano teacher, I learnt so much about digital pianos in the couple of hours I spent at Keysound. The technology has advanced so far since I bought my last Roland, 20 years ago, that I would have been lost without Steve’s guidance. Every aspect of my purchase at Keysound, including delivery and installation, was made so easy by Steve and his staff. I cannot fault this wonderful company!

The staff are friendly, and listen to you to establish your needs and wants, budget and prefernces.
Yamaha Pre-Owned PSRSX900 Keyboard
Exelent workstation, sounds are exelent, great value for money.
I am still exploring the many features of this keyboard (probably take me a while), only downside for me was the owners manual half english half french but no problem full english owners manual on Yamaha's web site along with many other downloads and video guides on many of the features.
sales person at keysound very helpfull, I would recomend this keboard/workstation for anyone wanting to play/record or sequence their own music, guitar/mic inputs for live sounds makes it easy to create songs with vocal backing for singer all on the keyboard/workstation if you want to without computer sequencers.
Casio Pre-Owned CDP120 Piano
Wonderful service at Keysound, friendly, very helpful, knowledgeable and always a smile to welcome you. Nothing is to much trouble.
Yamaha PSRSX920 Keyboard

Yamaha CLP825-R Piano
Keysound are an amazing, predominantly family business based in Hinckley. they have a wide range of upright and digital pianos and keyboards from many different brands
The staff are so friendly and helpful yet there is no pressure when you visit and I had plenty of time to look around and ask questions. Steve was incredibly knowledgeable and talked me through all the various features of the digital piano I wanted to buy. Delivery was prompt and the delivery men were pleasant, helpful and left no mess. I wasn't charged any extra for setting up the piano ( another store had quoted e £250 for this!)
The after service is fabulous too. I went back into store once the piano had been delivered and Ria went through any questions and showed me how to use the smart pianist app, also loading more songs onto this to help me with practicing
I was encouraged to contact them if I have any more issues or need to discuss anything
I would highly recommend Keysound if you're looking to buy any piano or keyboard, for the wide range of choice, the expertise of the staff and the lovely welcoming environment

Understood me and my requirements. They took time to allow me to play as many pianos as I needed before making my choice. Informative, friendly service to give me confidence to make the right choice for me. Delivery was outstanding
Kawai CN301-B Piano
Our musician visited the shop in Hinkley and was impressed with the service, that is why we chose to purchase from Key Sound even though we could have bought it cheaper elsewhere.
Yamaha PSRSX920 Keyboard
The service from Keysound was nothing short of perfect from start to finish. Purchasing was made easy with an excellent price for my PSR SX900. Delivery was very quick and the collection of my keyboard to be sent to Keysound was also very quick and efficient.
Excellent all round service from start to finish.
