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.

  • Compact and versatile keyboard amplifier with 150 watts of power
  • Redesigned power amp and universal power supply provide increased stability, improved bass reproduction, and reduced weight
  • Custom two-way speaker system with newly developed 12-inch woofer and horn tweeter
  • Onboard mixer with four stereo input channels, stereo auxiliary input, and master EQ with Shape switch
  • Output Select function on Channel 4 for monitoring click and guide tracks
  • XLR mic input, 1/4-inch line outputs, headphones output, and sub output
  • Chain another KC-400 with the Stereo Link function for more inputs and true stereo sound on stage
  • Metal jacks for increased durability
  • 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.

Heavy linen character, but a beautifully tailored suit!
Color: Beige, Size: 4, Color: Beige, Size: 4
This is a really nice linen suit! The jacket is beautifully made and well-tailored, with a fun speckled texture that has lots of pretty color variation (we ordered the beige). When I placed it side by side with a similar linen suit from another brand, the difference in the linen texture was really noticeable — this had a much stronger linen character that stands out! It has three useful pockets on the outside of the jacket, which is great for little hands. The only downside is that one of the inside pockets is just for show (faux), which was a bit surprising and somewhat disappointing for my little guy. The pants have pockets too, but they aren’t very deep — perfect for small treasures, but not much more. The pants are made from a lighter, thinner single-layer linen compared to the fully lined, double-layer jacket, which makes sense for comfort and easy movement. The pants didn’t come with a front crease ironed in, so you’ll want to press one yourself. The linen did pick up some creases from being folded in the package, but it doesn’t seem quite as wrinkly as some other linen fabrics I’ve tried. Still, like most linen clothes, especially for boys, the pants will need occasional ironing to keep them looking neat and crisp, especially after a day of play and general wear. The structured, lined jacket stays looking smoother and more put-together with less effort. It also came with a bow tie, a neck tie, and a tuxedo-style white shirt as extras. The ties aren’t great quality — they’d work fine for quick photos but probably won’t hold up to much actual wear. The formal white shirt feels a bit funny paired with the casual linen suit, but I don’t mind at all. We already have white shirts that we prefer, so we’ll use those instead. For us, the extras are really just bonus items we won’t plan on using. Overall, it’s a handsome little suit that’s perfect for special occasions like weddings, family photos, or holiday events. My kid looked adorable in it! The stronger linen texture on the jacket gives it a premium feel that I really like. Just be ready for a bit of extra care with the pants to keep everything sharp.

Great suit set
Color: Light Grey, Size: 4
It is incredibly attractive and includes everything a young child needs for a special occasion. The material is a 75% polyester and 25% linen blend, and the outer fabric feels remarkably smooth. Its unstructured design allows for an attractive, natural drape, and the blend conveniently allows for machine washing at home. As is typical with linen-based materials, the fabric can be naturally stiff and prone to wrinkling, so I recommend ironing or steaming it before use. The lightweight feel makes it an excellent choice for the spring, summer, and fall months. Overall, this suit offers exceptional value for the price.

Summer wedding kids suit
Color: Navy, Size: 10 Years, Color: Navy, Size: 10 Years
Bought this suit for my son in the 10 youth size and honestly was pleasantly surprised by the quality for the price. The navy color looks sharp and dressy without being too stiff or uncomfortable. The material has a little stretch, which helped it fit nicely and made it comfortable for him to move around in. The adjustable waist was a huge plus, especially for growing kids. It fit true to size overall, though the blazer sleeves were slightly long on my son. The pants had a nice slim look without being too tight. We paired it with white sneakers for a more modern look and it came out adorable. This would be perfect for weddings, graduations, concerts, communion, school events, or family photos. Overall, very happy with the purchase and would definitely buy again.

Very Modern Handsome Suit
Color: Grey, Size: 7 Years, Color: Grey, Size: 7 Years
This is an incredibly sharp looking suit for the little guy. Great price and features, too. I made a mistake in sizing up instead of down and first one was too sloppy on him and would need alterations. He is thin and very thin in the waist. There is a lot of adjustment with buttons in waistband and coat hides the bunching. This shirt and coat will easily take a fuller body than slim I believe. He loves posing in it and feels very classy. Best purchase for a formal suit that will last longer than most kids clothes size wise. Felt bad about returning but careful folding and packing got it good as new.
