Simplicity of design. Purity of sound. Introducing Robbie, Blue’snew Class-A discrete tube microphone and instrument preamplifier.All of the technical quality and design innovation that goes intoour line of award-winning microphones has been engineered intomaking Robbie one of the finest tube preamps available today.With no ICs and only the highest-quality discrete componentsfrom input to output, Robbie is one of the quietest (-131 dB EIN@ 50Ω) and most detailed (THD 0.006%) preamps on this (or anyother) planet. It features audiophile-grade ultra low noise metalfilm resistors and polystyrene capacitors, and provides the userwith the best of both worlds: An electronically-balanced, fully dis-crete input stage, tube gain stage (ECC88 twin triode), and anelectronically-balanced solid-state output stage. There is no switch-ing crossover distortion anywhere in the completely balancedaudio signal path. And if that’s not enough, Robbie achieves andamazing 34dB headroom before clipping! Robbie’s gorgeous designand ease of use will quickly make it one of the most valuable life-forms in your studio.
