■MOBILE CUBE is a battery-powered stereo mobile amplifier with custom 2.5 W + 2.5 W speakers. It has a wide range and a sound that transcends class, yet it has a compact design that makes it easy to carry around. It can be used not only for practice/rehearsal in the dressing room or in the car before the stage, but also for a small monitor on the live stage, a simple PA with a microphone or audio device connected, and a wide range of other applications unimaginable from a small body.

■MOBILE CUBE is equipped with a variety of input systems to accommodate various applications. Various devices, such as instruments, recorders, microphones, and digital audio players, can be directly connected for playback.
Instrument inputs support stereo inputs. Stereo sources such as keyboards and recorders are also beautifully monitored. It also supports guitar input, so you can connect acoustic and electric guitars directly and play them. In addition, the MOBILE CUBE also features a separate microphone input. You can mix instruments and microphones and output them at the same time, so you can also do keyboard/guitar and vocal singing.
And the stereo AUX in, ideal for connecting digital audio players and PCs, has two lines: an RCA pin and a mini stereo jack. You can play vocals and instruments while the song plays.
■MOBILE CUBE also supports battery power for use in places where power is difficult to obtain. High efficiency amplifiers allow up to 15 hours of continuous use with 6 AA alkaline batteries, even at full power. Of course, you can also drive it with an AC adapter (PSB -100: sold separately).
■Attachable to 3/8, 5/8 inch diameter stands
