Description
The KC-400 Stereo Mixing 4-Channel Keyboard Amplifier from Roland features 150W output power, four line-input channels, a dedicated auxiliary input, and support for an XLR vocal mic. Paired with the built-in 12″ woofer and horn tweeter, the keyboard amplifier can be used by musicians and producers to amplify pianos, organs, synthesizers, rhythm machines, and other electronic instruments.
The KC-400’s cabinet is a twin bass-reflex design that provides extended low-frequency response without distortion. There is an auxiliary channel with 1/8″ and RCA inputs for connecting smartphones, music players, or other devices. Channel 1 also includes an XLR input, allowing you to plug in a vocal mic for even more versatility.
This keyboard amplifier integrates into many environments. A 1/4″ line output enables you to interface with PA systems, stage monitors, and recording devices. There’s also a sub-out jack for connecting to a powered subwoofer, with level tied to the amp’s master volume for one-touch control. Plugging into the phones jack across the top of the unit, will mute the onboard speakers. This is suitable for private practice sessions and checking sounds on stage with headphones.
