The Quiet Time Coherent QTC40 (same as QTC1) has been called “the most accurate recording microphone available.” For classical location recording a matched pair will provide spectacular results. It is ideal for quieter, more detailed sources and doesn’t have most of the problems and limitations generally associated with competitive microphones. Its impulse response and diaphragm settling time is exceptional. Its sound is uncolored and it has no handling noise. The QTC40 will change the way you think about microphones.
