K2 – ?It cant be done?? Precision Variable Pattern Dual 1? Condenser Valve Microphone.
The R?DE K2 is the result of designing and building 1000?s of valve microphones. The
K2?s HF-1 capsule is the pinnacle of transducer technology. The sound quality combines
modern high-end specifications with the character and subtleties of the legendary 50?s mics.
Infinitely variable control of the K2?s polar patterns provides the freedom and flexibility to
excel in any recording situation. The K2 is another example of R?DE?s commitment to
building quality studio microphones to meet the exacting standards demanded by today?s
professionals.At the 2004 Frankfurt Music Messa, 56 of the most prestgious music industry
magazines voted the K2 the ?Best Studio Microphone of 2004?.
