UNIKA PRO 148

UNIKA PRO 148 is a professional single-channel active DI box designed primarily for electric guitar, bass, and other high-impedance instruments. It converts unbalanced signals into balanced low-impedance outputs for direct connection to mixers or preamps. Powered via +48V phantom power, it eliminates the need for batteries while ensuring consistent performance. With its custom isolation transformer and high input impedance, the PRO 148 delivers clean, dynamic sound with rich harmonics and minimal noise, making it ideal for live sound, studio recording, and fixed installations.
