The MOBILE BA: Battery-Powered Stereo Amplifier from Roland delivers high-quality stereo sound with flexible connectivity. It features a 15-hour battery life on six AA batteries. It also features reverb/echo effects, vocal cancelation, and an automatic anti-feedback function.
The MOBILE BA has a dedicated 1/4" microphone input, left and right 1/4" line-level inputs, and both RCA and a stereo 1/8" PC/Audio input. Each channel has an independent volume control. The Mic Echo knob mixes reverb/echo effects into the microphone channel. The PC/Audio channel has a push-button for its Center Cancel effect, which nullifies center-panned vocal material, so you can practice singing. The Tone knob acts as a brightness control, adding presence as it's turned clockwise.
The MOBILE AC weighs less than 6 pounds, includes a carrying strap and can be mounted on a mic stand for elevated placement.
