On the top panel, there is a new and innovative loop indicator, which consists of a 24-segment LED laid out in a circular pattern. You can quickly and easily determine the current status of the Rec/Overdub/Play modes. With a maximum 12 minutes of stereo recording time, the RC-1 is capable of capturing any extended performance that you can create or imagine. The stereo in/out jacks can be used with stereo effects and amplifiers. Additionally, they allow you to connect stereo instruments, such as synthesizers. Other convenient features include battery and AC power, as well as flexible external footswitching capabilities. The RC-1 is an especially great partner to start enjoying looping.Please message us if you have any questions.
