The RNDI-M brings the stunning tone & clarity of its award-winning counterparts to an even more compact and pedalboard-friendly format, with the exact same custom Rupert Neve Designs transformers and discrete FET input stage as the best-selling RNDI, RNDI-S and RNDI-8. By streamlining its feature set and housing the electronics in a rugged & more compact chassis, the RNDI-M fits neatly into any space and will allow even more musicians and engineers to tap into the uncompromised sonic power & vibrancy of a Rupert Neve Designs DI. Overview The RNDI-M provides instrument direct injection for electric guitar & basses, synthesizers, keyboards, piezo pickups, or any other instrument-level source. The discrete, Class-A circuit topology is built around Mr. Rupert Neve's custom transformers, resulting in outstanding sonic performance and strikingly natural sound from below 5Hz all the way up to well beyond 90kHz. It can handle input levels up to +20.5dBu, the low impedance, transformer-coupled output stage drives long lines with minimal loss, and the rugged steel chassis is designed for a lifetime of stage and studio use. Signature Sound The RNDI-M's signature sound is primarily the product of a custom Rupert Neve Designs transformer and a class-A, discrete FET input stage. The carefully orchestrated union of these two elements is key to the RNDI-M's unique accuracy, tone, and response. The Custom Transformer The RNDI-M's custom-wound output transformer provides exceptional passive isolation while adding musical harmonics and dimension to the sound. The low impedance, transformer-balanced output excels at driving long cable runs, and its performance is consistent regardless of the connected equipment. This is equally important for both live and studio environments where the audio signal may travel almost 100ft before hitting an amplifier. The Class-A, Discrete FET Amplifier The class-A, discrete FET input stage in the RNDI-M is powered by external +48V phantom with a high impedance input of 2.2 Megaohms that ensures consistent performance with a wide variety of instruments & other sources. The class-A design ensures that zero crossover distortion is added to the signal, which can add upper-order odd harmonics that are musically dissonant in nature. With the RNDI-M, the majority of harmonic content is a pleasing combination of 2nd order (octave) and 3rd order (fifth above octave). These musically relevant harmonics, present in subtle amounts, enhance the richness of the original signal and provide a distinctly musical response. Furthermore, the discrete aspect of the RNDI-M's design means there are no ICs or digital components that may cause negative effects on the tone. Wide Bandwidth, Giant Headroom The RNDI-M is flat within a quarter dB from 28 Hz to 60 kHz, +/-1 dB up to 90 kHz, with low frequency response all the way down below 5 Hz. However, measurements are only part of the equation: combine this extended bandwidth with the output transformer's harmonic enhancement, and a thunderous low-end emerges that feels an octave deeper than anything else without losing any midrange richness or top-end sparkle. The RNDI-M's uniquely high input headroom of +20.5 dBu is capable of handling not only instruments, but a wide variety of sources, such as synths, keyboards, drum machines and even pre-recorded material. This allows the RNDI-M to inject that coveted Rupert Neve Designs tone into a wide variety of sources.
