The Rupert Neve Designs RNDI Active Transformer Direct Interface provides powerful and vibrant direct sound capable of reproducing the full harmonic depth of basses, guitars, acoustic instruments, and professional line level sources.
With portable, powerful, larger-than-life tone for your instrument signals and amplifier signals, the Rupert Neve Designs RNDI is truly the first standalone DI worthy of the Rupert Neve name. The 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 the RNDI’s unique response.
The 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, however the output stage of the RNDI unrivaled at handling long runs with minimal losses.
In instrument mode, the RNDI’s high input headroom of +21.5dBU is capable of handling not only instruments, but professional, line level sources like interfaces, CD players and drum machines without a pad. This allows the RNDI to serve as a way to “Re-Preamp” any previously recorded track using your interface and a desired pre-amp. To do this, simply connect a channel output of the interface to the input of the RNDI and connect the RNDI’s output to the preamp and engage 48V. By “Re-Preamping” you can apply the tone of another preamp to the source and more accurately automate or control the drive level on the preamp.
In speaker mode, the RNDI can handle the screaming output of a 1000-watt power amplifier (92 Vrms or 266Vp-p) to capture the full tone of the instrument, preamplifier, EQ, inserts, and the amplifier’s output stages before it hits the speakers. This technique allows the engineer to avoid any bleed in a live environment and any unwanted tone added by the speaker cabinet or microphone. When used with modern speaker emulation plug-ins, this technique allows the engineer to take advantage of the flexibility of digital modeling, and the superior non-linear response of an actual analogue amplifier.
