RNDI

DI Box

From Rupert Neve Designs:

The RNDI contains a custom Rupert Neve-designed output transformer and class-A, discrete FET input stage. This carefully designed combination is the key to the RNDI’s unparalleled performance, delivering a powerful and vibrant direct sound that captures the full harmonic depth of basses, guitars, acoustic instruments, and even pre-recorded material.

With portable, powerful, larger-than-life tone for a variety of instrument and amplifier signals, the RNDI is truly the first stand-alone DI worthy of the Rupert Neve name.

After 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.
