User manual BLUE MICROPHONES ROBBIE

[. . . ] 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 our design philosophy. [. . . ] Any signal fed to the MIC input will appear at the LINE output when the MIC/INST selector switch is in its normal (out) position. OPERATIONS Line Out The balanced XLR male jack is for connection to your +4dBm balanced line-level input device with a XLR microphone cable such as the Blue Kiwi, Cranberry or Blueberry. Robbie's nominal operating level is 0dB = 1. 228V. Robbie's line output is wired pin 2 hot. Polarity (Ø) The SPST switch labeled Ø/REV reverses the signal polarity at a point immediately before the active input stage. When in its normal (out) position, the input signal passes unaffected. When depressed (in), the polarity is reversed. Pad The SPST switch labeled 0 dB/-20dB activates Robbie's pre-attenuation circuit. When in it's normal (out) position, input signal passes unaffected. When depressed (in) the input signal is attenuated by ­20dB to accommodate high-spl sources. Mic/Inst The SPST switch labeled MIC/INST determines which of Robbie's two inputs feeds the LINE output. When in its normal position (out), the input signal to the rear-panel XLR MIC input will appear at the LINE output. When depressed, (in), the input signal to the 1/4 Hi-Z front-panel input appears at the LINE output. +48V The SPST switch labeled +48V activates Robbie's phantom power circuit. When in its normal position (out), phantom power is OFF. When depressed (in), phantom power is ON. Most condenser microphones require phantom power as well as some active dynamic and ribbon microphones. The Blue Ball microphone is a good example of this. Check your microphone's specifications to determine whether it needs power. If it does not, be sure Robbie's phantom power circuit is OFF. Though most modern microphones of various designs are fairly robust, application of phantom power to a device not designed for it could result in permanent damage.
