Audio-Technica AT4040 Large-Diaphragm Cardioid Condenser Microphone

A blending of technical precision and artistic inspiration, the AT4040 is a side-address cardioid condenser microphone that features an advanced large diaphragm that's tensioned specifically to provide smooth and natural sonic reproduction. It offers remarkably low noise, wide dynamic range, and high-SPL (sound pressure level)-handling capability, making it a versatile addition to any mic locker. Its ultra-consistency means it excels in a variety of situations, both live and in the studio, and its symmetrical, transformerless low-noise circuitry delivers exceptional transient response and clean output signals for transparent reproduction of even the most problematic instruments and sound effects.

Its design includes visual and functional elements that enhance its pro-level bona fides, including a precision-machined, nickel-plated brass acoustic element baffle that provides superior element stability and optimal sensitivity. The open acoustical environment of its symmetrical housing minimizes unwanted internal reflections, and the surface-mount electronics meet Audio-Technica’s rigorous consistency and reliability standards.
