The Radial J48 is a professional-grade active DI box designed to deliver clean, full-bandwidth audio from high-output instruments such as active acoustic guitars, basses with onboard preamps, keyboards, and electronic instruments. Powered by 48V phantom power (with 9V battery fallback), it converts unbalanced high-impedance signals into balanced low-impedance mic-level signals with exceptional clarity, low noise, and zero coloration.
