Rupert Neves RNDI-S is a portable, rugged and active stereo DI speaker, whose special sound owes it to the combination of specially manufactured Neve transformers and discrete, Class-A FET amplifiers. The interaction of the components is the key to a powerful direct sound that reproduces the full harmonic depth and dynamics of basses, guitars, keyboards, acoustic instruments, professional line level and consumer devices. Whether stereo or mono source: The RNDI-S DI box makes every signal shine.
