Like all members of the CUBE family, the CM-30 is a breeze to transport. From gig to gig, session to session, this amp travels light and performs big. It's built to withstand the rigors of the road, thanks to its metal grill cover and protective corner covers. While the CM-30 is well suited for home studio and monitoring applications, it can be used for live monitoring onstage. Each CM-30 is equipped with three input channels, with one XLR input for mic/line, and two additional Aux inputs that support RCA pin (L, R) and stereo mini-phone connectors. So with one CM-30 you get four stereo inputs and one mono input. The Stereo Link function allows two CM-30s to be linked for true stereo output, which enables a total of eight stereo inputs, and two mono mic/line ins. The CM-30 offers more than enough inputs to simultaneously connect a microphone, a keyboard, a rhythm machine, and a CD player, or to function as a mini PA rig.
