Radial Pro48 | Compact Active Direct Injection Box

The Radial Pro48 is a compact, high-performance active direct injection (DI) box designed to cater to the demands of today's high-output musical instruments. With its groundbreaking 48V phantom-powered internal switching power supply, the Pro48 offers enhanced dynamic range and headroom, producing a smoother, more linear response that extends from 20Hz to well beyond 40kHz. This innovative technology ensures a natural and uncolored signal, often outperforming DI boxes that cost significantly more. Whether you're using battery-powered active basses or acoustic guitars, the Pro48 handles high output without distortion, making it an exceptional addition to any musician's gear.

Constructed to endure the rigors of the road, the Pro48 boasts a robust 14-gauge steel chassis. Its unique book-end design provides a protective shield around switches and connectors, while the internal I-beam construction safeguards the PC board from stress and potential damage to solder joints. Additionally, the full-bottom no-slip pad not only enhances mechanical isolation but also offers electrical insulation, thereby extending the lifespan of the Pro48. Combining stellar sonic performance with an affordable price tag, the Radial Pro48 sets a new standard in the realm of active DI boxes, delivering exceptional value and performance in one compact unit.
