The Earthworks QTC30 Omnidirectional Microphone is a 30kHz low noise omni mic designed for recording quiet sources. Delivering sound so detailed and real, the QTC30 brings recordings to life and delivers a truly accurate snapshot of your sound.

The Earthworks QTC30 Omnidirectional Microphone's near-perfect omnidirectional polar pattern is uniform across all specified frequencies, letting the microphone capture rich and consistent detail at any position around the capsule. With an extended 3Hz – 30kHz ruler-flat frequency response (with no frequencies exaggerated or attenuated) the result is a more accurate representation of the original sound.

The Earthworks QTC30 is time coherent, precisely capturing high and low frequency sounds with no phase errors, which will smear transients and create other time related distortions. With an SPL rating of 140dB the Earthworks QTC30 has plenty of headroom, so there is no need to worry about the microphone distorting. And there is no proximity effect, you can get the Earthworks QTC30 as close as you want to the sound source.

Ideal for for recording quieter sources such as vocals, strings and distant miked orchestras or choirs, the Earthworks QTC30 low noise omni is also an excellent choice for drum overheads, close-miked wind and percussion instruments, and foley.

What We Think

If we had to sum up the Earthworks QTC30 in one word, it would be pristine. While using it in the studio, the first thing that hits you is just how real everything sounds. There’s an openness and clarity to the QTC30 that feels effortless, paired with a full-range, natural response that captures sources exactly as they are — no hype, no smoothing, just honest sound. We’ve had great results putting the QTC30 on just about anything. Drum overheads and drum room? Huge and detailed. Acoustic guitar and other stringed instruments? Clear, balanced, and beautifully natural. Woodwinds, piano, choir — it just keeps delivering. The omni pattern adds a sense of space and realism that’s hard to fake, and it’s honestly a little mind-blowing how much detail and range Earthworks gets out of such a small capsule. They’ve been doing this from the very beginning, and the QTC30 is another great example of why their microphones are trusted whenever realism truly matters.
