Rupert Neve RNDI-S Stereo Active Transformer Direct Interface

An expanded two-channel version of Rupert Neve's best-selling RNDI, providing massive tone and headroom for all of your instruments and stereo sources.

The RNDI-S signature sound is the product of custom Rupert Neve Designs transformers and class-A biased, discrete FET amplifiers. 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. With portable, powerful, larger-than-life tone, the RNDI-S is ready to make your stereo or mono direct sources shine.

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 their unique response.
