Here's the details from Alesis...
The TransActive Solo is a complete, battery-powered PA system in a single, portable cabinet musicians can carry in one hand. It has inputs for all kinds of instruments, a dock for iPod, a built-in amplifier and a two-way loudspeaker for complete sound reinforcement. Performers can play small gigs with just one speaker box thanks to the TransActive Solo's built-in carry handle for easy transport to and from the show.
Musicians can connect their guitar, microphone and other instruments directly to the TransActive Solo's input section. It supplies a combination XLR â€“ 1/4-inch input for microphones, additional 1/4-inch inputs that support both guitars and line-level instruments, and RCA inputs for drum machines, samplers and other line-level audio devices. With TransActive Solo's built-in dock, performers can dock their iPod and use it as a backing track or interlude-music source.
Users can take the TransActive Solo with them for remote gigs such as street performances or parties without a wall power source, thanks to the built-in rechargeable battery. The system can deliver up to 12 hours of cordless amplification without a charge, or run limitlessly on wall power. The TransActive Solo has a built-in amplifier for high efficiency and all-in-one performance. Its large speaker delivers excellent low end and powerful, crisp highs.
