Roland KC-990 Amplifier

A Stereo Amp Designed for Keyboard Dynamics

A good keyboard amplifier must respect the dynamics, touch, and stereo width of a digital piano while remaining clear with denser synth sounds. With dedicated speakers for lows and highs, this model offers stable projection, solid bass, and clear definition, useful for working on attack details as well as holding a band mix. The channels allow connecting multiple keyboards (or a keyboard and a module), plus an auxiliary source, then adjusting levels with a single gesture. The 3-band equalizer facilitates adaptation to the room, and the effects section adds value during rehearsals. The LINE OUT outputs and STEREO LINK function simplify sending signals to a mixer or expanding the system, while the headphone output helps monitor your settings without disturbing the environment.
