The Roland MOBILE BA: A Portable & Battery-Powered Amp

Small and tough, this stereo amplifier supports all types of electronic instruments and audio devices, and can be used whenever, wherever. Whether hooking up microphones, electric and acoustic guitars, keyboards, drum machines, MP3 players, or virtually anything else you can think of, the MOBILE CUBE will have you rocking in no time.

Big Things In A Small Package
No larger than a briefcase, MOBILE CUBE is a dream come true for musicians on the go. Because it's battery-powered, it can be operated anywhere (but, you know, watch out for noise violations) — simply plug in, turn on, and start rocking out. Two 4" 2.5 W high-quality speakers offer stereo sound that seems to defy the MOBILE CUBE’s physical size.

Onboard Stereo Effects
The MOBILE CUBE boasts high-quality stereo reverb and chorus effects. You can add some fire to your guitar performance, sweeten up your vocals a bit, or simply immerse your mixes in a lush stereo sound field. Center Cancel is also available for diminishing the vocals in pre-recorded music — ideal for karaoke and play-along performance(s).

General Features

Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
