Built for mixing engineers, synth enthusiasts, and touring musicians, this stereo DI captures the full harmonic depth of basses, guitars, keyboards, and consumer devices. Whether in the studio or on the road, the RNDI-S ensures your mono and stereo sources deliver a \"record-ready\" sound from the very first note.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"1103\" height=\"621\" src=\"https:\/\/www.youtube.com\/embed\/CTgWjE7GJVI\" title=\"Quick Start: RNDI-S Stereo Active Transformer Direct Interface\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSignature Neve Transformer Warmth\u003c\/strong\u003e\u003cbr\u003eAt the heart of the RNDI-S are two custom Rupert Neve-designed output transformers that introduce musical harmonics and dimension while providing exceptional passive isolation. These transformers allow you to drive long cable runs—often exceeding 30 metres—with minimal signal loss or high-frequency degradation, ensuring consistent performance in both live and studio environments.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDiscrete Class-A FET Precision\u003c\/strong\u003e\u003cbr\u003eThe active circuitry features a discrete, Class-A FET input stage powered by standard 48V phantom power. This high-impedance design (2.2M Ohms) prevents loading on passive pickups, delivering a transparent signal free from the crossover distortion commonly found in integrated circuits or digital components. The result is a bold, vibrant tone with rich low-end and sweet highs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVersatile Connectivity for Modern Workflows\u003c\/strong\u003e\u003cbr\u003eSpecifically designed to accommodate the needs of modern performers, the RNDI-S includes a dedicated 3.5mm stereo input for seamless integration with mobile devices, laptops, and tablets.
