Designed as a special effects microphone for professional use,  the Bing Carbon Microphone adapts the technology of the telecommunications industry to provide a unique way of grabbing sounds.  It can be used to achieve a desirable "lo-fi" aesthetic or blended with a high fidelity sound to impart an interesting texture.  The sound of the mic can be described as a bandwidth limited, granulated distortion with rich harmonic overtones.  It achieves saturated and compressed distortion while imparting way less noise than high gain clipping distortion, making it a viable alternative to stomp boxes or plugin processing.  
To understand what makes the sound of a carbon microphone have interesting characteristics, it is important to consider how it converts the physical vibrations of the air that we perceive as sound into an electrical signal.  Source sound waves cause sympathetic vibrations of a diaphragm which applies a varying pressure to a capsule containing carbon granules.  The changing pressure causes the electrical resistance of the mass of granules to change.  Since a DC voltage is applied to the granules, their changing resistance modulates the current thereby creating an AC waveform or audio signal that is a mechanically distorted representation of the sound source.    

The Bing Carbon Microphone is now being shipped with an external power supply interface, much like a tube condenser microphone.  An included 4 pin XLR cable connects the microphone's output to the interface box to provide 5 volts bias voltage to the carbon transmitter.  This interface can be powered with a 9V battery or a wall wart power supply.  It contains a voltage regulator and a 150Ω microphone level output transformer, capable of driving long lines and microphone preamps via it's XLR output.   Please see the user manual PDF below for more information, and please contact if you have any questions!
