Looking to capture delicate sound sources, acoustic ensembles, and room ambience with extreme realism and ultra-wide bandwidth? The Earthworks QTC40 (Quiet Time Coherent) is a premier 40kHz omnidirectional condenser microphone designed for critical studio recording and high-resolution sound capture.
Experience breathtaking acoustic realism, ultra-low self-noise, and an astounding 40kHz ultrasonic frequency reach with the Earthworks QTC40 40kHz Omnidirectional Condenser Microphone. As part of Earthworks' esteemed Quiet Time-Coherent (QTC) series, this high-definition free-field microphone is meticulously engineered to capture the most delicate sources, subtle room acoustics, and intricate micro-dynamics with absolute transparency.
Why Choose the Earthworks QTC40?
Capturing extremely quiet sounds or complex acoustic environments often introduces unwanted self-noise or high-frequency smearing with conventional microphones. The Earthworks QTC40 overcomes these barriers by combining a near-perfect omnidirectional polar pattern with an ultra-fast impulse response and an expanded linear frequency range reaching up to 40kHz. It preserves the true physical character, depth, and air of a performance space without artificial coloration or phase anomalies.
