Radial Engineering Pro48 Active Direct Box with 48V Phantom Power
Product Introduction
The Radial Engineering Pro48 is a high-performance active direct box designed for professional live sound, stage performances, worship venues, recording studios, and AV applications. Powered by 48V phantom power, the Pro48 delivers exceptional signal handling, increased headroom, and superior audio quality for both active and passive instruments.
Engineered with an innovative internal switching power supply, the Pro48 provides greater dynamic range and lower distortion than conventional active DI boxes. Whether you're connecting an acoustic guitar, active bass, keyboard, or other line-level instruments, the Pro48 ensures clean, natural, and transparent sound reproduction.
Product Description
Professional musicians and audio engineers require a direct box that can accurately capture instrument signals without coloration, distortion, or signal degradation. The Radial Pro48 is specifically designed to meet these demands.
Unlike standard active DI boxes, the Pro48 incorporates a sophisticated internal switching power supply that dramatically increases headroom while maintaining ultra-low distortion. This advanced design allows the Pro48 to handle high-output active bass guitars, acoustic instruments with onboard preamps, keyboards, and other powerful audio sources that may overload conventional DI boxes.
With a smooth and linear frequency response extending from 20Hz to beyond 40kHz, the Pro48 faithfully preserves every detail of your instrument's natural tone. The result is a balanced, noise-free signal that is ideal for front-of-house systems, stage monitoring, digital mixers, recording interfaces, and broadcast environments.
Built to Radial's renowned professional standards, the Pro48 combines exceptional sonic performance with rugged steel construction for years of reliable service on stage and in the studio.
