The carefully orchestrated union of these two elements is key to the unique response of the RNDI-S, delivering a powerful and vibrant direct sound capable of reproducing the full harmonic depth of basses, guitars, keyboards, acoustic instruments, professional line-level sources and consumer devices with a 3.5mm jack. \u003cbr\u003e\u003cbr\u003eWith portable, powerful, larger-than-life tone, the RNDI-S is ready to make your stereo or mono direct sources shine.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eThe Development of the RNDI\u003c\/b\u003e\u003cbr\u003eAfter coming into existence during an experimentation with new transformer designs, the RNDI was fine-tuned over a series of listening tests against the 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. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eActive + Passive: The Best of Both Worlds\u003c\/b\u003e\u003cbr\u003eThe RNDI-S and RNDI’s signature sound is the product both of new custom Rupert Neve-designed transformers and class-A biased, discrete FET amplifiers. The carefully orchestrated union of these two elements is key to their unique response.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTHE TRANSFORMERS\u003c\/b\u003e\u003cbr\u003eThe custom transformers provide superior passive isolation while adding musical harmonics and dimension to the sound. The low impedance, transformer-balanced output excels 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 unamplified signal may travel almost 100ft before hitting an amplifier. In other designs, these high-capacitance lines cause major reductions in high frequencies – not so with the RNDI.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTHE CLASS-A, DISCRETE FET AMPLIFIERS\u003c\/b\u003e\u003cbr\u003eThe class-A \u0026amp; discrete FET amplifier in the RNDI is powered by 48V phantom, and creates a very high impedance input of 2M Ohms that ensures consistent performance with a wide variety of instruments. 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, the overwhelming majority of harmonic content is 2nd order (octave) with some 3rd order present (fifth above octave). These musically relevant harmonics, present in subtle amounts, actually add to the richness of the original signal. And the discrete aspect of the RNDI design means there are no ICs or digital components that can have negative effects on the tone.\u003cbr\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eCustom Rupert Neve Designs transformers for rich, powerful tone\u003c\/li\u003e\n\u003cli\u003eExceptional performance with any instrument\u003c\/li\u003e\n\u003cli\u003eUnrivaled clarity from discrete FET amplifiers\u003c\/li\u003e\n\u003cli\u003eDrives long lines with minimal loss\u003c\/li\u003e\n\u003cli\u003eRugged steel frame built for life on the road\u003c\/li\u003e\n\u003cli\u003ePowered by dual 48V phantom power\u003c\/li\u003e\n\u003cli\u003eExcellent phase coherence at all frequencies\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eNOISE\u003c\/b\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eMeasured Output, un-weighted, 22 Hz - 22 kHz, source impedance 150 Ohm.\u003c\/li\u003e\n\u003cli\u003eBetter than -110 dBV\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cb\u003eINPUT IMPEDANCE\u003c\/b\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eInstrument Setting: 2.2 Meg Ohm\u003c\/li\u003e\n\u003cli\u003e3.5 mm Input: 95 Kilohm\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cb\u003eOUTPUT IMPEDANCE\u003c\/b\u003e\u003cbr\u003eLess than 40 Ohms\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFREQUENCY RESPONSE\u003c\/b\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e+\/- 0.25 dB from 30 Hz - 63 kHz\u003c\/li\u003e\n\u003cli\u003e+\/- 1 dB from 12.5 Hz - 120 kHz\u003c\/li\u003e\n\u003cli\u003e-3 dBu @ 5 kHz\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cb\u003eMAXIMUM INPUT LEVEL \u003c\/b\u003e\u003cbr\u003eInstrument = +20.5 dBu \u003cbr\u003e\u003cbr\u003e\u003cb\u003eMAXIMUM OUTPUT LEVEL \u003c\/b\u003e\u003cbr\u003e+11.5 dBu output at maximum input level\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTOTAL HARMONIC DISTORTION AND NOISE\u003c\/b\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e@ 1 kHz, -20 dBu Input Level, no load : 0.009% Typical (2nd and 3rd Harmonic)\u003c\/li\u003e\n\u003cli\u003e@ 1 kHz, +20 dBu Input Level, no load : 0.35% Typical (2nd and 3rd Harmonic)\u003c\/li\u003e\n\u003cli\u003e@ 20 Hz, -20 dBu Input Level, no load : 0.9% Typical (2nd and 3rd Harmonic)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cb\u003eCROSSTALK @ 10 kHz \u003c\/b\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eInstrument Input: -115 dB\u003c\/li\u003e\n\u003cli\u003e3.5 mm Input: -108 dB\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cb\u003ePOWER REQUIREMENTS\u003c\/b\u003e\u003cbr\u003ePhantom power, 4.5mA @ +48VDC\u003cbr\u003e\u003cbr\u003e\u003cb\u003eWEIGHT\u003c\/b\u003e\u003cbr\u003e1.5lbs\u003cbr\u003e\u003cbr\u003e\u003cb\u003eDIMENSIONS\u003c\/b\u003e\u003cbr\u003e7” long x 5”wide x 1.75” high\u003cbr\u003e\u003cbr\u003e\u003cb\u003eMOUNTING OPTION\u003c\/b\u003e\u003cbr\u003e19” Rack Shelf, 4 hole pattern (bottom of unit) for 6-32 machine screws","brand":"Rupert Neve Designs","offers":[{"title":"Default Title","offer_id":40078868185223,"sku":"RNEVERNDI-S-FBAU","price":9139.0,"currency_code":"MXN","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0343\/4368\/2183\/products\/rupert-neve-designs-pro-audio-interfaces-rupert-neve-designs-rndi-s-stereo-active-transformer-direct-interface-rneverndi-s-fbau-29586242830471.jpg?v=1661796143","url":"https:\/\/www.chicagomusicexchange.mom\/en-mx\/products\/rupert-neve-designs-rndi-s-stereo-active-transformer-1580849","provider":"Chicago Music Exchange","version":"1.0","type":"link"}
