Roland KC-990 Stereo Keyboard Amplifiers
The Roland KC-990 is a premium stereo mixing keyboard amplifier built to deliver powerful, full-range sound for demanding live performances and rehearsal environments. Driven by 320 watts of stereo power through a dual 12-inch woofer and twin horn tweeter configuration, it produces rich, detailed audio with deep lows and crisp highs that do justice to modern keyboards, digital pianos, and synthesizers.
The onboard four-channel stereo mixer makes the KC-990 a versatile hub for your entire rig, accepting multiple keyboards and a microphone simultaneously without the need for an external mixer. Built-in stereo effects including reverb, chorus, tremolo, and a rotary speaker simulation add polish to your sound, with optional footswitch control for hands-free operation during performance.
Comprehensive connectivity options include XLR and quarter-inch line outputs for sending signal to a PA system or recording interface, multiple auxiliary inputs for backing tracks, and a stereo link function that pairs two KC-990 units together for expanded input capacity and wider stereo coverage on larger stages. Built-in casters and side-mounted handles keep this road-ready amplifier easy to transport despite its substantial output.
