Legendary tone, unquestionable reliability. Eight channels of the superb-sounding RNDI in one rack space.<\/strong><\/h4>\n

With over 25,000 channels shipped since its launch in 2015, the RNDI is firmly established as the direct interface of choice for many of the world\u2019s most discerning musicians and engineers. Its custom transformers and discrete FET amplifiers deliver a vibrancy and clarity that captures the full harmonic depth of any source, and its unquestionable reliability has led to its adoption by thousands of touring artists. <\/strong><\/p>\n

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\u2019t require extra work \u2013 it\u2019s just there.<\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n

The RNDI-8 consists of eight independent channels of RNDI Active Transformer Direct Interface<\/a> in a single rack space, providing instrument direct injection for electric guitar & bass, synthesizer, keyboard, piezo pickup, or any other instrument-level source.<\/p>\n

The discrete, class-A circuit topology is built around Mr. Rupert Neve\u2019s 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 typical 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\u2019 steel construction is designed for a lifetime of stage and studio use.<\/p>\n

Transformer + Discrete FET: The Best of Both Worlds<\/h4>\n

The RNDI-8\u2019s signature sound stems from the custom-designed transformers and class-A, discrete FET input amplifiers. The carefully designed union of these two elements is key to the RNDI-8\u2019s unique accuracy, tone, and response.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

THE EIGHT CUSTOM TRANSFORMERS<\/strong>
\nThe RNDI-8\u2019s 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.<\/p>\n

THE CLASS-A, DISCRETE FET INPUT AMPLIFIERS<\/strong>
\nThe class-A & 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\u2019s design means there are no ICs or digital components to potentially cause negative effects on the tone.<\/p>\n

Giant Headroom, Wide Bandwidth<\/h4>\n

The RNDI-8 has a uniquely wide bandwidth with a frequency response stretching from 5Hz all the way past 90kHz. However, measurements are only part of the equation: couple this extended bandwidth with the output transformer\u2019s harmonic enhancement and an absolutely thunderous low-end emerges, adding an unparalleled feeling of depth. All this happens without compromising any of the midrange richness or top-end sparkle that defines your instrument.<\/p>\n

Maximum input level is a massive +21dBu (typical), making the RNDI-8 capable of handling not only instruments but also professional line-level sources like interfaces and drum machines. And with the addition of a – 10dB pad, that number soars to +31dBu \u2013 more than enough for even the highest-output DJ mixers. This makes the RNDI-8 incredibly versatile, enhancing the sound of nearly any connected instrument or source.<\/p>\n

Two Distinct Ground Lift Options<\/h4>\n

Most direct interfaces include a ground lift switch at the output, and the RNDI-8 includes this standard DI \u2018lifting\u2019 option via eight individual \u2018Pin 1 Isolate\u2019 switches on the rear panel<\/strong>. Engaging this button will usually eliminate common sources of hum in the signal path.<\/p>\n

However, the RNDI-8 also includes eight ground lift buttons<\/strong> on the front panel which separate each channel\u2019s circuit ground from the chassis ground<\/strong>, providing another helpful option to detect and eliminate unwanted ground hum.<\/p>\n
