The discrete, class-A circuit topology is built around Mr. Rupert Neve’s custom transformers, resulting in outstanding sonic performance and supremely natural sound from 5Hz all the way out to well beyond 90kHz. Each channel can handle input levels up to +21dBu (+31dBu 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.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eThe Eight Custom Transformers\u003c\/b\u003e\u003cbr\u003eThe RNDI-8’s custom-wound output transformers provide isolation while adding musical harmonics and dimension to the sound. The low impedance, transformer-balanced outputs excel at driving long cable runs, and the performance is consistent regardless of the connected equipment. This is important for both live and studio environments where the unamplified signal may travel 100ft or more before hitting an amplifier.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eThe Class-A, Discrete FET Input Amplifiers\u003c\/b\u003e\u003cbr\u003eThe class-A \u0026amp; discrete FET input amplifiers in the RNDI-8 are powered by 48V phantom and create a high impedance input of over 2M Ohms, ensuring consistent performance with a wide variety of instruments. The class-A design eliminates crossover distortion that can otherwise be added to the signal and introduce unwanted upper-order odd harmonics. With the RNDI-8, the harmonic content is derived from the octave (2nd order) and fifth above octave (3rd order) relative to the fundamental. 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-8’s design means there are no ICs or digital components to potentially cause negative effects on the tone.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eGroundbreaking Direct Tone\u003c\/b\u003e\u003cbr\u003eWhen class-A, discrete amplifiers meet Rupert’s custom transformers, magic happens. The RNDI-8 contains the unique components and design knowledge that makes it worthy of the Rupert Neve name.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eHuge Headroom\u003c\/b\u003e\u003cbr\u003eMaximum input level is a massive +21dBu, making the RNDI-8 capable of handling not only instruments but also professional line-level sources like interfaces and drum machines. With the addition of a -10dB pad, that number soars to +31dBu – more than enough for even the highest-output DJ mixers.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eRugged Solid Steel Frame\u003c\/b\u003e\u003cbr\u003eThe rugged steel 1U chassis features an industrial-grade powder coating and is built to withstand the severe stresses of life on the road.
