UNIKA PRO 248

UNIKA PRO 248 is a professional dual-channel active DI box designed for instruments like electric guitar, bass, keyboards, and line-level sources. It converts high-impedance unbalanced signals into low-impedance balanced outputs, making it ideal for direct connection to mixers or audio interfaces. Powered via +48V phantom power, it eliminates the need for batteries while delivering clean, dynamic sound with excellent noise isolation. Its custom isolation transformers and high input impedance ensure rich harmonics, clarity, and minimal interference, making it suitable for both live sound and studio applications.
