Roland KC-80 50W 3-Channel Keyboard Amplifier

The Roland KC-80 is a 50-watt portable keyboard amplifier that combines professional-grade sound with true portability. Its custom two-way speaker system — a 10-inch (25 cm) woofer paired with a dedicated tweeter in a twin bass-reflex cabinet — delivers full-range audio reproduction that accurately conveys the tonal character of stage pianos, synthesizers, and organs in rehearsal rooms, small stages, and recording environments.

Three input channels provide flexible connectivity: Channel 1 accepts both a balanced XLR signal (switchable mic/line from –50 to –20 dBu) and a 1/4-inch phone input, while Channels 2 and 3 offer additional 1/4-inch line inputs — all with individual level controls. A dedicated auxiliary input (RCA phono + 1/8-inch stereo) handles backing tracks and secondary audio sources. Two-band EQ (LOW and HIGH knobs) and master volume complete the control surface.

The KC-80 provides a 1/4-inch LINE OUT (+4 dBu), a 1/4-inch SUB OUT (+4 dBu) for connecting a powered subwoofer, and a TRS headphone jack (1/4-inch, mono signal) for private monitoring. Metal jacks throughout provide reliable, road-ready durability. The optional ST-A95 speaker stand raises the KC-80 to ear level for better sound dispersion on stage.
