The KC-600 Stereo Mixing 4-Channel Keyboard Amplifier from Roland is a combo amplifier intended for musicians and producers to amplify pianos, organs, synthesizers, rhythm machines, and other electronic instruments. It features four inputs with channel 1 supporting 1/4' and a 3-pin XLR balanced mic input, channels 2 and 3 with 1/4' connectors, and channel 4 with 1/4' and dedicated RCA and 3.5mm auxiliary inputs for smartphones, music players, or other devices. Balanced XLR and 1/4' stereo line outputs enable you to interface with PA systems, stage monitors, and recording devices. Plugging into the phones jack, located on the back of the unit, will mute the onboard speakers, making it suitable for private practice sessions and checking sounds on stage with headphones.

The KC-600's cabinet features a twin bass-reflex design, providing extended low-frequency response without distortion. The highly efficient 200W amplifier powers the 15' woofer and horn tweeter, which provide full-range audio powerful enough to ensure the entire audience can hear your performance. 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. Four caster wheels for transport are also included.
