In the Footsteps of the JDI, Radial DNA Within Reach
Designed as the most affordable option to the famous JDI, the Radial Pro DI retains the essentials that made the brand's reputation: reliability, musicality, and tolerance to high levels. It maintains a sleek design and ultra-compact format, perfectly suited for stages, project studios, and rental fleets where a serious DI without extras is required. A stereo version also exists under the name Pro D2, for dual-output sources.
Who Is It For and What Are Its Uses?
The Pro DI is suitable for bassists, keyboardists, and active acoustic guitarists seeking a clean and stable line to the console or interface. Ideal for both live and recording situations, it easily integrates on a pedalboard, in a backline rack, or in a flight case, establishing itself as a reliable "plug-and-play" tool for busy sound engineers and musicians.
Design and Features Serving the Sound
High-Performance Transformer
At the heart of the Pro DI, a custom Radial transformer ensures silent instrument-to-line conversion, excellent handling of powerful signals, and a smooth response from 20 Hz to 18.5 kHz. The sound remains natural, with defined lows and smooth highs, ideal for electroacoustic instruments and keyboards.
Protection and Reliability
Internal shielding limits electromagnetic interference, while the steel chassis protects connectors and switches. The non-slip pad contributes to mechanical and electrical isolation, enhancing durability on the road.
Simplified Use
The
-15 dB pad manages very hot sources, and the ground lift switch effectively eliminates ground loops. No power supply required: the passive topology guarantees instant and hassle-free operation.
