Quiet Time Coherent Series

For recording quieter sources such as vocals, strings, orchestras and choirs
The QTC Series (Quiet Time Coherent) is designed for recording quieter sources such as vocals, strings and distant miked orchestras or choirs. These low-noise omnis are also an excellent choice for drum overheads, close-miked wind and percussion instruments. 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. All models are available in matched pairs.
Omni – 6Hz to 30kHz. The QTC30 is an economical alternative to our popular QTC40 (same as the QTC1). Its 30kHz high frequency response and small size make it ideal for capturing high quality sound where space is a concern. The QTC30 is an excellent choice in cost vs. performance.
Omni – 4Hz to 40kHz. Our most popular microphone! The QTC40 (same as the QTC1) is the microphone of choice for demanding professionals in studio and remote recording. No serious recording studio or recordist should be without one.
Omni – 3Hz to 50kHz. The QTC50 is the microphone for those who demand the very best. It is ideal for digital recording with sample rates up to 192kHz, and even higher where every nuance of sound must be captured.

Matched pairs come in custom, handcrafted wooden boxes
QTC Series models are available in matched pairs or matched groups of any number.

"I use my QTC40s on every session. They are extremely musical, and balanced from top to bottom."
