Roland KC-880 Stereo Keyboard Amplifier The KC-880 builds on the famous high-quality KC sound with a new stereo design, powered through a 320-watt stereo power amplifier, two 12-inch woofers and two horn tweeters. This design delivers the most accurate sonic representation of the performance, with wide, clear full-spectrum sound. New onboard stereo effects such as Tremolo, Rotary, and Reverb, give musicians a whole new range of keyboard and vocal performance possibilities. The new stereo Chorus effect also gives the KC-880 unprecedented spatial depth and detail. Flexible I/O options come standard on the KC-880. There are a total of five stereo input channels—four stereo instrument inputs, and an additional stereo AUX input with dedicated volume control to play external sources like rhythm machines, CD/MP3 players, or mixers. The KC-880 also includes XLR line outputs to a front-of-house mixer, stereo headphone output, and more. The Stereo Link function enables the chaining of two KC-880s for an expanded stereo stage sound.
