What We Think

The Earthworks QTC1 is all about one thing: absolute honesty.

This is a microphone designed to get out of the way and capture exactly what’s in front of it, with a level of speed and accuracy that’s hard to overstate. Transients are incredibly detailed, the frequency response is exceptionally flat, and the sense of realism it delivers can be almost startling—especially on acoustic instruments and natural spaces.

What makes the QTC1 special isn’t hype or coloration—it’s precision. You’re not getting added warmth or built-in character here. Instead, you’re getting a true representation of the source, which makes it an invaluable tool when transparency matters most. Whether you’re recording classical music, acoustic performances, percussion, or room ambience, it captures nuance in a way that feels immediate and lifelike.

That level of detail also makes it a powerful problem-solver. If something doesn’t sound right, the QTC1 will tell you—clearly. But when everything is dialed in, the results are incredibly rewarding.

For engineers who value accuracy, realism, and pristine capture, the Earthworks QTC1 is a microphone that consistently delivers exactly what you put in—nothing more, nothing less.

Manufacturer's Description from Earthworks

The Earthworks QTC1 Omnidirectional Condenser Microphone Stereo Pair is a game-changer for studio recording enthusiasts seeking unparalleled sound clarity and precision. With Earthworks' Quiet Time Coherent (QTC) technology, these mics are engineered to capture the subtle nuances of quiet audio sources like vocals, strings, and acoustic instruments without introducing noise. The omnidirectional polar pattern ensures an even capture across all angles, making it an ideal choice for drum overheads, orchestras, and choir recordings.

These microphones boast an impressive frequency range from 3 Hz to 40 kHz, offering a super-fast transient response that captures every sonic detail with accuracy and realism. This feature allows the mics to handle high sound pressure levels up to 142dB without distortion, ensuring your recordings remain clear and uncolored even in loud environments. The QTC1s are perfectly matched in sensitivity and frequency response, providing a coherent and balanced recording experience.

Their flat frequency response and fast impulse response make them an excellent tool for both professional studios and home recording setups that demand high definition and precise sound reproduction. Whether you're recording for sound design or live performances, the QTC1s deliver the tonal purity and low noise floor that audiophiles and professional musicians crave.

Key Features:

Matched pair of omnidirectional condenser microphones
Frequency response: 3 Hz to 40 kHz
Handles sound levels up to 142dB
Requires 48V Phantom Power
Extremely low noise floor
Ideal for capturing vocals, strings, choirs, and acoustic instruments
Fast transient response ensures minimal distortion

About Manufacturer

Earthworks was formed by David Blackmer, the inventor of dbx, to realize his vision of upgrading the entire audio chain to a new standard of sonic realism. David's goal of creating high definition tools with which to capture the sound and experience of "being there" is based upon a strong evidence that there is more to human hearing than the range of frequencies which can be heard as tones. We are convinced that audio equipment with extended frequency response and faster, cleaner time domain performance will yield more life-like results. Traditional audio methadology appears to be based on working around the limitations, imperfections, and personality quirks of the equipment, and calling the ones you like "assets". WE believe that any part of the audio chain can be improved to the point where the standard is so high that any product meeting it will be indistinguishable from any other product meeting the same standard, and that an audio system built to such standard can achieve sonic reality. This standard, for electronic equipment, is met by our Zero Distortion Technology. We support the concept of recording acoustic events accurately enough to capture the sound as it happened in the room. This approah allows you to make sonic coloration and texture choices later, when you can consider them carefully and still have recourse. Life-like accuracy is the best starting point for whatever unique coloration you may wish to add.
