The Z-Kick Series offers excellent “bang for buck” portable sound systems for instructors who need excellent, punchy sound on a budget. Just plug your iPod/Mp3 player into the built-in mixer with the included connector cable -and rock your class! Plug a wireless mic system into the mixer’s second channel for a complete –and ultra portable- group ex sound system. The Z-Kick comes in 3 sizes to accommodate every size class. And since these are ‘active’ speakers with built-in power amps, you can easily add more Z-Kicks for more sound.
