More Info

Up to 4-Channel Mixing

KC-series amplifiers feature a flexible mixing section designed with the performing musician in mind. Our flagship models feature up to four stereo inputs, and KC amps include a Microphone input and stereo Auxiliary input for connecting CD players.

Stereo Link Capabilities

The KC-550 and KC-350 include Roland’s Stereo Link feature for chaining two amplifiers. Using a single cable, you can connect two KC amps for true stereo sound while controlling them both from the amp nearest you on stage.

Subwoofer-Ready

Want more low end? Simply add an optional subwoofer like Roland’s new KCW-1. Connections are easy, thanks to the Subwoofer output found on all new KC amps. Now even the most affordable models can sound huge!

Made for the Road

KC amps are built for life on the road. All models have built-in handles for easier transportation (the KC-550 also includes casters) and a rugged design with heavy-duty carpeting, protective edges and an all-metal grille.
