Audio Technica AT4040

AT4040 Features:

1. Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity.
2. Technically advanced large diaphragm tensioned specifically to provide smooth, natural sonic characteristics.
3. Externally polarized (DC bias) true condenser design.
4. Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections.
5. Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of highspeed transients.
6. State-of-the-art surface-mount electronics ensure compliance with AT’s stringent consistency and reliability standards.
