Earthworks QTC Series Microphones   
QTC30, QTC40, QTC50

The QTC series (Quiet Time Coherent) is designed for recording quieter sources such as vocals, strings and distant miked orchestras or choirs. Earthworks’ reputation for realism is based on these distinctive omnis. Their degree of clarity is unparalleled. Our claim of Time Coherent Response means these models do not smear the time domain as most microphones do. Earthworks microphones have exceptional impulse response and diaphragm settling time. QTC microphones handle sound levels up to 142dB with no proximity effect or handling noise.

Earthworks QTC30 - Omni - 6Hz to 30kHz

Earthworks QTC40 - Omni - 4Hz to 40kHz  
Earthworks QTC40mp - QTC40 matched pair  

The QTC40 is the microphone of choice for demanding professionals in studio and remote recording. It 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.
