The Rupert Neve Designs RNDI Active Transformer Direct Interface is a professional-grade DI box designed to provide the full harmonic richness, warmth, and clarity that Rupert Neve is known for. Whether you’re tracking instruments in the studio or performing on stage, the RNDI delivers the highest-quality direct signal, making it an essential tool for musicians, engineers, and producers seeking premium sound from their instruments.

At the heart of the RNDI is a Rupert Neve custom transformer, which adds subtle harmonic saturation and warmth to your signal, making your instruments sound fuller and more musical. This transformer-based design ensures that even complex sources, like bass guitars and high-output instruments, are captured with pristine clarity and detail, while benefiting from the harmonic character that only Neve transformers can provide.

The high-headroom design of the RNDI allows it to handle powerful signals without distortion or unwanted coloration. This makes the RNDI ideal for a variety of instruments, from electric bass and guitar to keyboards, synthesizers, and line-level sources such as outboard gear. Whether you're driving it hard with an active bass or capturing the nuance of a vintage keyboard, the RNDI delivers an accurate, musical sound with incredible fidelity.

The balanced XLR output provides clean, noise-free signal transmission, ensuring that your audio remains pristine over long cable runs in both live and studio settings. This makes the RNDI perfect for direct connection to mixing consoles, preamps, or audio interfaces, whether you're in the studio recording a track or performing live on stage.

The RNDI is powered by 48V phantom power, allowing it to integrate seamlessly into any professional audio system without the need for external power supplies or batteries. Simply connect the RNDI to a phantom-powered input, and you're ready to go. This simple setup makes it easy to deploy the RNDI in any environment, from studios to concert venues, without complicated rigging or additional gear.

To ensure clean and interference-free sound in any environment, the RNDI features a ground lift switch, which helps eliminate hum caused by ground loops. This ensures your signal remains clear and free of unwanted noise, making it especially useful in live sound applications where electrical interference can be an issue.

The versatility of the RNDI makes it ideal for a wide range of applications. For electric guitars and basses, it provides a rich, natural DI tone that captures the full harmonic range of the instrument. For keyboards and synths, the RNDI delivers clean, full-bodied sound without distortion, even at high output levels. It also excels with line-level devices, ensuring that your outboard gear or playback sources sound as good as they can through any sound system.
