The Roland Roland KC-400 Stereo Mixing Keyboard Amplifier allows for 4 channels of stereo inputs to be mixed together and then sent out as a single clear stereo signal whilst benefiting from projection and monitoring of your instruments and audio at close range. With a 150-watt amplifier, 3-band EQ and rock-solid build quality, the KC-400 has a lot to boast about.

4 channel mixer and mic input

Although thought of as a keyboard amp, a key feature of this KC series amp is the on-board 4-channel stereo-capable mixer and the varied connectivity which it offers. The first channel has dual use as either a XLR microphone input or line level 1/4" jack inputs. Channels 2 and 3 and 4 all offer 1/4" jack connectivity, great for connecting your keyboards to, although they could also be used for any other instruments with a line-level output.

Each of the 4 stereo capable channels has their own level control on the top of the amp, meaning you can set up the perfect mix easily. On top of this there's a pair of RCA connectors which are a great fit when connecting playback equipment such as smartphones or MP3 players, a useful feature for both practice and performance.

150 watts of power

The KC-400 is a solid middleweight of the KC family, offering an impressive 150 watts of power. This may not be the most powerful keyboard amplifier on the market, but it wasn't designed to be. This level of output is great as a studio practice amp, for powerful on stage re-enforcement during gigs or as a dedicated amplifier at medium-sized venues.

External speakers and sub connectivity

For the rare times when you do need more power Roland have added a pair of great breakout options. The line out connection is a fairly standard feature, but an appreciated one none-the-less. You could use this 1/4" jack output to easily give a sound engineer a feed of everything that you're sending to the KC-400. The subwoofer out is a bit more of a unique feature, letting you connect the amp directly to a compatible subwoofer to add some real depth to your output. Want to shape your sound even further? There's a dedicated 3-band EQ to do just that.

The KC-400 will make an excellent workhorse in the studio and on the stage and reinforce your sound with astonishing detail and a good amount of power. If you need heavyweight sound that you can carry around with the option of mixing stereo signals and sending to front of house, the KC-400 is your amplifier.
