Earthworks has become the accepted standard for affordable, reliable reference and measurement microphones. These microphones are accurate in the time domain and frequency response. Earthworks measurement microphones are optimized for clean, very fast impulse performance to provide accurate wideband response. They have virtually no handling noise and are remarkably stable with respect to temperature and atmospheric conditions. Our M Series measurement microphones are used by SMAART™, MLSSA™, Spectrafoo™, TEF™ and RTA in addition to acoustic measurement systems manufactured by dbx, DEQX and others. All models are available in matched pairs.
The Quiet Time Coherent QTC30 has an excellent cost/performance ratio. With a frequency response to 30kHz and excellent impulse response, it will reproduce sounds with incredible detail that are true and life-like, making it an ideal and affordable choice for recording applications. Its small stainless steel body is 6.5 inches long and has no handling noise. Earthworks QTC30 is an extraordinarily accurate microphone. It provides that famous Earthworks Sound with lower self noise than was thought possible with such a small a diaphragm. The QTC30 delivers flat, extended Time Coherent response from below 6Hz to beyond 30kHz, typically within ±0.5dB from 20Hz-20kHz. More importantly, its impulse response is faster and cleaner than any other recording microphone except for the Earthworks QTC1. Its clean impulse performance allows the QTC30 to transduce wave forms exactly giving you a true and accurate representation of sonic events as they happen in the air. What this means for you is stunning, lifelike realism. It offers you the experience of being there.
The QTC30 is among the best possible choices for ambient room miking but it is also exquisite for close miking of quieter more delicate sources. This microphone is a very good choice for all applications where natural, uncolored pick up of sound is the desired result. The QTC30 effortlessly captures the full size and natural texture of many difficult and complex sources ranging from Location Recording of Classical, Jazz, Ethnic, Folk and Pop music to Percussion, Piano, Guitar, Upright Bass, Strings, Vocals, Brass, and Woodwinds. It is also useful for those applications when you want to capture natural sounds with the feeling of reality intact, like Sound Effect, Foley, ADR and sampling of any audio source.
