Simply stunning.
Simplicity of design. Purity of sound. Robbie is Blue’s stellar Class A discrete tube microphone and instrument preamplifier. All of the technical quality and design innovation that goes into Blue's line of award-winning microphones has been engineered into making Robbie one of the finest tube preamps available today. With no ICs and only the highest-quality discrete components from input to output, Robbie is one of the quietest (-131 dB EIN @ 50 ?) and most detailed (THD 0.006%) preamps on this (or any other) planet. It features audiophile-grade ultra low noise metal film resistors and polystyrene capacitors, and provides the user with the best of both worlds: An electronically-balanced, fully discrete input stage, tube gain stage (ECC88 twin triode), and an electronically-balanced solid-state output stage. There is no switching crossover distortion anywhere in the completely balanced audio signal path. And if that’s not enough, Robbie achieves an amazing 34dB headroom before clipping! Robbie’s gorgeous design and ease of use will quickly make it one of the most valuable lifeforms in your studio.

Features:

  • Fully discrete Class-A signal path — completely balanced from input to output
  • Solid-state transformerless input stage coupled with twin triode (ECC88) vacuum tube gain stage insures ultra low noise (-131 dB), maximum detail and exceptionally musical harmonic saturation
  • Amazing 34 dB headroom before clipping
  • Front panel instrument input turns Robbie into a DI — will enhance any bass, electric guitar, synth or drum machine
  • A work of art that you’ll proudly display on top of your console or on your workstation
