RNDI-8
DI Box
From Rupert Neve Designs:
The RNDI-8 puts eight channels of this beloved circuit into a single rack space, making it the ideal solution for high-end stage rigs, studios, and synth enthusiasts. With the RNDI-8, stunning direct sound doesn’t require extra work – it’s just there.
The RNDI-8 consists of eight independent channels of RNDI Active Transformer Direct Interface in a single rack space, providing instrument direct injection for electric guitar & bass, synthesizer, keyboard, piezo pickup, or any other instrument-level source.
The discrete, class-A circuit topology is built around Mr. Rupert Neve’s custom output transformers, resulting in outstanding sonic performance and supremely natural sound from below 5Hz all the way up to well beyond 90kHz. Each channel can handle typical input levels up to +20.5 dBu (+30.5 dBu with the pad engaged), the low impedance transformer-coupled output drives long lines with minimal loss, and the rugged chassis’ steel construction is designed for a lifetime of stage and studio use.
