Many mics are too bright - they don't use the intended HF de-emphasis circuit (*partial list below) Do you have mics that are too bright or harsh? Learn why- and what to do about it... Sibilance, excessive brightness or harshness in many mics is caused by a K67-type capsule being used without the special circuitry it needs. The Neumann K67 capsule was designed with a built-in high frequency response peak. The response peak was then de-emphasized in the U 67 and U 87 by special circuits. This design created an acoustic pre-emphasis / electronic de-emphasis system offering headroom extension, sibilance reduction and control over timbre balance.
