The RNDI-S is an expanded, two-channel version of the best-selling Rupert Neve Designs RNDI, designed to deliver massive tone, clarity, and headroom for all instruments and stereo sources. Ideal for basses, guitars, keyboards, acoustic instruments, line-level signals, and consumer devices, the RNDI-S offers the legendary warmth and harmonic richness of Rupert Neve’s custom transformer and FET designs.
Key Features
-
Custom Rupert Neve Transformers: Provides rich, full-bodied tone and enhances harmonic content.
-
Discrete Class-A FET Amplifiers: Delivers unrivaled clarity, detail, and dynamics.
-
Exceptional Instrument Performance: Works flawlessly with electric bass, guitar, keyboards, and more.
-
Dual Hi-Z Inputs: Two unbalanced 1/4" inputs with parallel THRU jacks for versatile routing.
-
3.5mm Input: Accepts line-level or consumer device signals.
-
Input Select: Easily switch between 1/4" and 3.5mm sources.
-
48V Phantom Power LEDs & Ground Lifts: Supports active instruments and resolves ground-loop issues.
-
Transformer-Balanced XLR Outputs: Provides strong, clean signal to mixers, interfaces, or recording systems.
-
Phase-Coherent Signal: Maintains excellent phase integrity at all frequencies, even across long cable runs.
Why It Stands Out
The RNDI-S combines Rupert Neve’s legendary transformer tone with Class-A FET amplification, resulting in a direct box capable of capturing every nuance of your performance. Whether you’re recording, performing live, or sending stereo signals to a mixing console, the RNDI-S ensures your instruments sound vibrant, detailed, and full-bodied. Its versatile I/O and dual-channel design make it perfect for stereo instruments or multiple sources in a single, portable package.
