The Z111 is a high-performance passive direct injection box designed for professional touring and studio environments. It features a specialized light-shielded transformer design intended to provide superior frequency response and high-end openness. The unit is optimized for splitting instrument signals between an amplifier and a mixing console or DAW without signal degradation. Built with a focus on "Swedish design" principles, it emphasizes a clean signal path and the use of high-quality components. Its passive circuitry requires no external power, making it a reliable tool for eliminating impedance mismatches.
