Earthworks QTC SeriesEarthworks 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.
