Revered for its smooth and airy frequency response, if there were ever a microphone that was the epitome of classic, high-fidelity sound, it would be the C12. While it is a fantastic choice for all instruments, the C12 lends itself exceptionally well to drum overheads, acoustic guitar, and vocals. Its silky top end provides plenty of air without sounding harsh or artificial. Its midrange speaks clearly and articulately, capturing the source with a natural presence. Its low end is tight and focused, perfectly balanced with the rest of the frequency range. The TELEFUNKEN C12 builds upon the original design with the implementation of cathode self-biasing operation, a quieter and more consistent configuration than the initial fixed-bias configuration.
