Omni Recording Microphone
Haunting accuracy. Stunning realism. 360° of sound.
Explore the Earthworks QTC40.
Legacy building sound.
The Earthworks QTC40 eliminates the gap between form and functionality, revealing levels of realism you didn’t think possible.
From the rich, mid lows to the crisp, airy highs, sacrifices in sound are a thing of the past with the QTC40 condenser.
Delivering sound so detailed and real, the QTC40 brings recordings to life and delivers a truly accurate snapshot of your sound.
Its 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 – 40kHz ruler-flat frequency response (with no frequencies exaggerated or attenuated) the result is a more accurate representation of the original sound. The QTC40 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 QTC40 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 QTC40 as close as you want to the sound source.
Ideal 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, and foley.
