Up to 8 hours operating time are guaranteed, using the built-in rechargeable lithium ion battery.

A ¼-inch output also lets you daisy-chain additional Transport 12s to cover an even larger area with powerful, great sound.


''We know there's a critical need for true high-fidelity, high-output sound in situations where there's no access to AC power. Until the Transport 12, there simply wasn't an adequate AC cable-free solution to this product. The Transport 12 solves it and has the operational flexibility and adaptability that makes it perfect in almost any circumstance''. - said Dustin Plumb, Product Manager for Alto Professional.
