Rupert Neve Designs RNDI-SThe Rupert Neve Designs RNDI S is a stereo version of the RNDI Active transformer direct box, known for its high headroom and larger than life tone. The Rupert Neve Designs RNDI S uses a Class A design with a custom transformer and discrete FET amplifiers that delivers an extended frequency response between below 10Hz all the way above 100kHz. This results in a full and deep sound with right tones and musical harmonics without sacrificing clarity.
