The Alto Professional TRANSPORT 12 is a portable AC/battery-powered sound system. This compact, easily-transportable unit solves the problem of delivering true high-fidelity sound even when theres no access to AC power. TRANSPORT 12 accomplishes this by operating for up to 8 hours off its built-in rechargeable lithium ion battery, which provides an AC cord-free power supply for its internal 400-watt digital Class D amplifier.
