This carefully designed combination is the key to the unparalleled performance of the RNDI-S, delivering a powerful and vibrant direct sound that captures the full harmonic depth of basses, guitars, acoustic instruments, pre-recorded material and even consumer devices via the 3.5mm stereo input jack.\u003c\/p\u003e\n\u003cp\u003eWith portable, powerful, larger-than-life tone, the RNDI-S is ready to make your stereo or mono direct sources shine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Development of the RNDI\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAfter coming into existence during an experimentation with new transformer designs, the RNDI was fine-tuned over a series of listening tests against the most popular high-end DIs available. It was in these tests where the RNDI always seemed to add another dimension to the sound and bring the instruments to life. The lows felt richer, deeper and fuller, and the highs had outstanding clarity without any added harshness.\u003c\/p\u003e\n\u003cp\u003eMost importantly, the design team noted:\u003c\/p\u003e\n\u003cp\u003e\"As musicians, the RNDI consistently stood out as the DI we wanted to play through.\"\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSignature Sound\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe signature sound of the RNDI-S is the result of new Rupert Neve-designed output transformers and class-A, discrete FET input stages. The carefully orchestrated union of these elements is key to the accuracy, tone and response of the RNDI-S.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTHE TRANSFORMERS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe custom output transformers provide exceptional isolation while introducing musical harmonics and dimension to the sound. The low impedance, transformer-balanced outputs excel at driving long cable runs, and performance is immensely consistent regardless of the connected equipment. This is very important for both live and studio environments where the audio signal may travel over 100ft before hitting an amplifier.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTHE CLASS-A, DISCRETE FET AMPLIFIERS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe class-A, discrete FET input stage in the RNDI-S is powered by 48V phantom, providing a high impedance input of 2.2M Ohms that ensures consistent performance with a wide variety of instruments. The class-A design introduces no crossover distortion to the signal, which can add upper-order odd harmonics that are musically dissonant in nature. With the RNDI-S, 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. And the discrete nature of the RNDI-S design means there are no ICs or digital components that can have negative effects on the tone.\u003c\/p\u003e\n\u003ch2\u003eCONTROLS \u0026amp; I\/O\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2x 1\/4\" INPUTS\u003c\/strong\u003e\u003cbr\u003eHi-Z unbalanced inputs with 2.2M Ohms input impedance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2x 1\/4\" THRU JACKS\u003c\/strong\u003e\u003cbr\u003eParallel 1\/4\" jacks used to send signal to an amp or speaker.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3.5MM INPUT\u003c\/strong\u003e\u003cbr\u003eStereo unbalanced input with 95 kOhm input impedance.
