A 3U box takes three slices; half-rack gear pairs two units side by side in one.; it lives on a belt or in a pocket, one per performer, every show. Its metal construction is a meaningful detail — bodypacks take real abuse on stage, and plastic housings tend to show it faster. At $549, it sits in the working-professional middle ground: serious enough for touring use, accessible enough for a band making their first real IEM investment.
