Flat Like No Other
With an extended 3Hz – 30kHz ruler-flat frequency response (with no frequencies exaggerated or attenuated) the result is a more accurate representation of the original sound.

Massive in Its Precision
With an SPL rating of 140dB the QTC30 has plenty of headroom, so there is no need to worry about the microphone distorting.
Professional products
designed with professionals in mind
In audio, our perception of what feels real and natural is incredibly sensitive to resolution in the time domain. In particular, the level of detail present in the initial transient is responsible for much of our sense of content, meaning, and frequency balance. This includes defining attributes like “timbre”, “texture”, and “air”. Earthworks’ blazingly fast technology ensures that every performance sounds like life
