Simplicity of design. Purity of sound. Meet Robbie, BLUE's 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 ohms) and most detailed (THD 0.006%) tube preamps available today. 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 and amazing 34dB headroom before clipping!

Elegance and simplicity are the driving forces behind BLUE's design philosophy. Robbie is no exception. The front panel features a single large backlit potentiometer (gain) and 1/4 hi-Z instrument input. On the back, you'll find the power cable input, power switch, balanced XLR mic input, balanced XLR line output, polarity switch, -20 dB pad, input selector switch (mic/instrument) and phantom power on/off.

Robbie's gorgeous design and ease of use will quickly make it one of the most valuable lifeforms in your studio.

  • Great Vocal Preamp!

This is a great Preamp for recording Vocals. To me it sounds like a preamp only ver. of a Avalon (and a lot less money) This unit adds a warm tone to your signal and keeps the recording crystal clear.
