Radial Engineering Pro48 Active Direct Box for Instrument and Line-Level Signal Conversion with Low-Noise Headroom Performance

The Radial Engineering Pro48 is a high-performance active direct box designed for converting instrument and line-level signals into clean, balanced outputs for professional audio systems. Engineered for acoustic guitar, bass, keyboards, and other electronic instruments, it delivers exceptional clarity, high headroom, and ultra-low noise performance in both live and studio environments.

Powered via 48V phantom power, the Pro48 eliminates the need for batteries while maintaining consistent, reliable operation. Its advanced active circuitry is optimized for high signal integrity, ensuring that the natural tone and dynamics of the instrument are preserved even over long cable runs.

The Pro48 is particularly well-suited for instruments with passive pickups, offering improved impedance matching that results in tighter low end, smoother highs, and reduced signal loss. A built-in low-noise design helps prevent distortion and interference, making it ideal for demanding stage and recording applications.

Housed in a rugged steel enclosure, the Pro48 is built to withstand heavy touring use while maintaining consistent professional performance.
