Roland KC-990 - stereo combo amplifier with effects for keyboards, with an output power of 320 W, offers four line input channels, a dedicated auxiliary input, and an XLR connector input for a vocal microphone. It is equipped with two 12" woofers and two tweeters. The amplifier can be used by musicians and producers to amplify pianos, organs, synthesizers, drum machines, and other electronic instruments.
The cabinet features a design that provides extended low-frequency response without distortion. There is an auxiliary channel with inputs equipped with 1/8" and RCA connectors for connecting external devices such as smartphones, music players, or other devices. Channel 1 also includes an XLR connector input, allowing you to connect a vocal microphone for greater versatility.
It offers a 1/4" jack output that allows you to connect to PA systems, stage monitors, and recording devices. Additionally, the stereo XLR outputs benefit from selectable ground lift, which eliminates background noise that may occur when connected to a PA system. Connecting to the headphone jack located on the top of the amplifier will mute the speakers, which is useful for quiet practice sessions and for checking sound on stage with headphones. Four wheels are also included to facilitate transport.
