The 1A soloist system is the perfect first-time audio system for marching band programs looking to amplify a soloist or duet for the first time. This system consists of a microphone, small format mixer with built-in effects, a single active (powered) full-range loudspeaker, and everything needed to connect it all together. 
 
The entire rig fits on a single all-terrain field cart, including the available portable power stations by EcoFlow. While the compact size and ease-of-use is designed to be approachable and "entry-level" for any team of band directors, the individual components are rugged and built for the long haul. 
 
For larger groups already using a bigger speaker system, the 1A Soloist System can be used on-field for localizing the sound of featured soloists; a use-case that makes great use of the available portable power station options, which eliminate the need for power extension cables.
